h1. Release Notes for Sirius

{toc:style=disc|minLevel=2|maxLevel=3} 

This document contains the release notes for recent major releases of Sirius. See also "the release notes from previous versions":Release_Notes_Previous.html for details about older releases.

h2(#sirius5.0.0M7). Changes in Sirius 5.0.0M7

h3. User-Visible Changes

* <span class="label label-success">Added</span> An experimental mode to serialize representations in a different file is available with system property @createRepresentationInSeparateResource=true@. That means all new representations will be saved, by default, in a separate file with *.srm extension.

* <span class="label label-info">Modified</span> The label alignment of Notes from the Palette has been modified from Juno to Luna or newer versions of Eclipse. The label alignment changed from TOP & CENTER to MIDDLE & LEFT. The initial alignment (TOP & CENTER) has been restored.


h3. Specifier-Visible Changes

* <span class="label label-info">Modified</span> The transient layer has been introduced in Sirius 5.0. (Refer to "Sirius Specifier":specifier/diagrams/Diagrams.html#Transientlayer and "Sirius User":user/diagrams/Diagrams.html#transientLayer documentation in Diagram chapter). Transient layer is an additional layer containing only decorations or tools. If you have such layer in your VSM, users may encounter some unexpected behaviors. If the layer is not _active by default_ then it will not be applied when opening your diagram even if it was activated before. If the layer is _active by default_ then it will be automatically applied when opening your diagram. We consider this behavior as a known limitation and an enhancement may be done in a further release. In the meantime, there is a workaround which consists to add a fake mapping (that is any mapping with its fields empty) so that the layer will not be considered as transient.

h3. Developer-Visible Changes

h4. Add @org.eclipse.sirius.ui.editor@

This plugin provides a session editor showing loaded models, representations and viewpoint activation status of the session. It has functionalities allowing to change the viewpoint activation status, to create/remove representations or to load unload external models. The graphical block showing loaded models is integrated with CNF. You can provide content extension to its viewer by using an id matching the pattern @org.eclipse.sirius.ui.editor.graphicalcomponents.semanticModelsViewer.contentExtension.*@. You also can provide action extension by using an id matching the pattern @org.eclipse.sirius.ui.editor.graphicalcomponents.semanticModelsViewer.actionExtension.*@. The extension will be selectable/unselectable by using a @Customize View@ button on the models block header.

h4. Changes in @org.eclipse.sirius.ui@

* <span class="label label-success">Added</span> An interface @org.eclipse.sirius.ui.business.api.editor.ISiriusEditor@ has been added to gather @org.eclipse.sirius.ui.editor.SessionEditor@ and @org.eclipse.sirius.ui.business.api.dialect.DialectEditor@ under the same abstraction. It allows to provide @org.eclipse.sirius.ui.business.api.session.IEditingSession@ saving functionalities for session editor or any new editor that is not a dialect editor. 

* <span class="label label-success">Added</span> A method @getSiriusEditors()@  has been added to interface @org.eclipse.sirius.ui.business.api.session.IEditingSession@. It allows to retrieve all @org.eclipse.sirius.ui.business.api.editor.ISiriusEditor@ that are registered in the session.

* <span class="label label-info">Modified</span> The method @attachEditor(DialectEditor)@ from the interface @org.eclipse.sirius.ui.business.api.session.IEditingSession@ has its parameter type modified from @DialectEditor@ to the new abstraction @ISiriusEditor@ to provide saving capabilities with other editors than the dialect ones.

* <span class="label label-info">Modified</span> The method @detachEditor(DialectEditor)@ from the interface @org.eclipse.sirius.ui.business.api.session.IEditingSession@ has its parameter type modified from @DialectEditor@ to the new abstraction @ISiriusEditor@ to provide saving capabilities with other editors than the dialect ones.

* <span class="label label-info">Modified</span> The method @detachEditor(DialectEditor, boolean)@ from the interface @org.eclipse.sirius.ui.business.api.session.IEditingSession@ has its first parameter type modified from @DialectEditor@ to the new abstraction @ISiriusEditor@ to provide saving capabilities with other editors than the dialect ones.

* <span class="label label-success">Added</span> Two new methods have been added to the interface @org.eclipse.sirius.ui.business.api.viewpoint.ViewpointSelection.Callback@: @selectViewpoint(Viewpoint, Session, boolean, Set<Viewpoint>, IProgressMonitor)@ and @deselectViewpoint(Viewpoint, Session, Set<Viewpoint>, IProgressMonitor)@. These methods add a new parameter that is a set of viewpoints compared to the same methods without these parameters. These set contains all viewpoints that will be deactivated/activated in addition of the one that is asked to be deactivated/activated. It allows the callback implementation to better handle viewpoint dependencies interaction by being able to know if missing dependencies will be activated or deactivated.

h4. Changes in @org.eclipse.sirius@ 

* <span class="label label-success">Added</span> The method @org.eclipse.sirius.business.api.dialect.DialectServices.canCreate(EObject, RepresentationDescription, boolean)@ has been added to better control the checks done by already existing @org.eclipse.sirius.business.api.dialect.DialectServices.canCreate(EObject, RepresentationDescription)@ method. The new boolean allow to deactivate the check verifying that the viewpoint of the given description must be activated so the method can return true.
* <span class="label label-success">Added</span> The @org.eclipse.sirius.viewpoint.description.DAnnotation.references@ feature has been added. It allows to have some information without having to search them into the entire model of the Sirius session. Ideally only elements from semantic resources of the session should be referenced or else it may broke the session behavior either because resolving too soon EObject in the session or because adding a resource that is not known by Sirius session.
* <span class="label label-success">Added</span> @org.eclipse.sirius.business.api.query.EObjectQuery.getImpactedRepDescriptorFromDAnnotationData()@ method has been added to help retrieve the @DRepresentationDescriptors@ which owned @DAnnotation@ are referencing a given @EObject@ with @DAnnotation.references@.
* <span class="label label-success">Added</span> @org.eclipse.sirius.viewpoint.DRepresentationDescriptor#repPath@ attribute has been added to hold the representation path since the @org.eclipse.sirius.viewpoint.DRepresentationDescriptor#representation@ feature is derived. This attribute is not intended to be modified by client. You should use @org.eclipse.sirius.viewpoint.DRepresentationDescriptor.setRepresentation(DRepresentation)@ or @org.eclipse.sirius.viewpoint.DRepresentationDescriptor.updateRepresentation(DRepresentation)@ instead.
* <span class="label label-success">Added</span> @org.eclipse.sirius.viewpoint.DRepresentationDescriptor.updateRepresentation(DRepresentation)@ has been added to update the repPath attribute according to the given representation. This method is intended to be called if the representation instance is still the same but requires to recompute the repPath.
* <span class="label label-success">Added</span> @org.eclipse.sirius.business.api.query.FileQuery.isSrmFile()@ has been added to indicate if the file extension is dedicated to a file containing representations.
* <span class="label label-success">Added</span> @org.eclipse.sirius.dRepresentationLocationRule@ extension point has been added to customize the resource location of new representations. See "Provide representation location rule (experimental)":extensions-provide_representation_location_rule.html for more details.
* <span class="label label-success">Added</span> @org.eclipse.sirius.business.api.session.danalysis.DRepresentationLocationRule@ interface has been added to provide a customized rule to the @org.eclipse.sirius.dRepresentationLocationRule@ extension point.
* <span class="label label-success">Added</span> @org.eclipse.sirius.business.api.helper.SiriusUtil.REPRESENTATION_FILE_EXTENSION@ constant has been added to reference the new *.srm extension.
* <span class="label label-success">Added</span> @org.eclipse.sirius.business.api.session.Session.getSrmResources()@ has been added to provide the list of representation resources (serialized as *.srm files by default).
* <span class="label label-success">Added</span> @org.eclipse.sirius.business.api.query.ResourceQuery.isAirdOrSrmResource()@ has been added to know whether the resource is a srm resource (@org.eclipse.sirius.business.api.query.ResourceQuery.isSrmResource()@) or an aird resource.
* <span class="label label-success">Added</span> @org.eclipse.sirius.business.api.query.ResourceQuery.isSrmResource()@ has been added to know whether the resource contains a @DRepresentation@ as root element.
* <span class="label label-success">Added</span> @org.eclipse.sirius.diagram.ui.tools.api.migration.DiagramCrossReferencer.DiagramCrossReferencer(Collection<Resource>)@ constructor has been added to compute the cross references on a list of resources.
* <span class="label label-info">Modified</span> @org.eclipse.sirius.viewpoint.DRepresentationDescriptor#representation@ feature is now derived, transient and volatile. The representation is compute by using the @org.eclipse.sirius.viewpoint.DRepresentationDescriptor#repPath@ attribute.

h4. Changes in @org.eclipse.sirius.common@ 

* <span class="label label-success">Added</span> @org.eclipse.sirius.common.tools.api.util.SiriusCrossReferenceAdapterImpl.setFeatureToBeCrossReferencedWhiteList(Collection<EReference>)@ to set a white list of references that must be referenced even if the reference is derived.
* <span class="label label-success">Added</span> @org.eclipse.sirius.common.tools.api.util.SiriusCrossReferenceAdapterImpl.isIncluded(EReference)@ has been overridden to consider features in the white list.
* <span class="label label-success">Added</span> A new extension point, @org.eclipse.sirius.common.package_meta_data@ has been added. It can be used to associate user-oriented meta-data to Ecore metamodels, identified by their @nsURI@: a user-oriented name/label (as opposed to the technical nsURI), a (short) description/documentation, and a list of suggested EClasses defined in the EPackage that are good candidates as root model elements.

h4. Changes in @org.eclipse.sirius.common.ui@ 

* <span class="label label-danger">Removed</span> The @org.eclipse.sirius.common.ui.tools.api.dialog.FeatureEditorDialog@ class has been removed; use the @org.eclipse.emf.edit.ui.celleditor.FeatureEditorDialog@ equivalent provided by EMF directly instead.

h4. Changes in @org.eclipse.sirius.diagram.ui@

* <span class="label label-success">Added</span> Constants @org.eclipse.sirius.diagram.ui.business.api.query.ViewQuery.SPECIFIC_STYLES@ & @org.eclipse.sirius.diagram.ui.business.api.query.ViewQuery.VERTICAL_ALIGNMENT@ have been added to retrieve the initial label alignment of Notes from the Palette (see "user-visible changes":Release_Notes.html#UserVisibleChanges ). Currently the vertical alignment can not be changed (potential new feature later).
* <span class="label label-info">Moved</span> The methods of interface @org.eclipse.sirius.diagram.ui.tools.api.format.SiriusFormatDataManagerWithMapping@ that are @getFormatData(FormatDataKey, RepresentationElementMapping)@ and @addFormatData(FormatDataKey, RepresentationElementMapping, AbstractFormatData)@ have been moved into the interface @org.eclipse.sirius.diagram.ui.tools.api.format.SiriusFormatDataManager@ to reduce interface numbers for less complexity.
* <span class="label label-danger">Removed</span> The methods @getFormatData(FormatDataKey key)@ and @addFormatData(FormatDataKey key, AbstractFormatData formatData)@ have been removed from interface @org.eclipse.sirius.diagram.ui.tools.api.format.SiriusFormatDataManager@ because they were deprecated.
* <span class="label label-danger">Removed</span> The interface @org.eclipse.sirius.diagram.ui.tools.api.format.SiriusFormatDataManagerWithMapping@ has been removed because all its methods have been moved into interface @org.eclipse.sirius.diagram.ui.tools.api.format.SiriusFormatDataManager@

h4. Changes in @org.eclipse.sirius.table@

* <span class="label label-danger">Removed</span> The @DTableElementSynchronizer@ _EClass_ has been removed from the table meta-model. It only defined _EOperations_ and has been replaced with an equivalent (internal) plain Java class.

h4. Changes in @org.eclipse.sirius.ui@

* <span class="label label-danger">Removed</span> The old _Model Request Interpreter_ view is not available anymore. It is superseded by the _Interpreter_ view, which comes from the Acceleo project but does not actually depend on Acceleo or AQL and can be installed separately (using the feature @org.eclipse.acceleo.ui.interpreter@, which is available directly from the Sirius update-sites). The corresponding interface @org.eclipse.sirius.ui.tools.api.views.interpreterview.InterpreterView@ has been removed. Technically, the implementation code for the old _Model Request Interpreter_ view is still present if needed during the transition, but not exposed or used anywhere. It will be removed in a future version. 

h4. Changes in @org.eclipse.sirius.tests.swtbot.support@

* <span class="label label-success">Added</span> The method @getTreeItem(SWTBotTreeItem[], String, boolean, boolean)@ has been added in @org.eclipse.sirius.tests.swtbot.support.utils@ to retrieve recursively a @SWTBotTreeItem@ in a @SWTBotTreeItem@ array. Compared to @getTreeItem(SWTBotTreeItem[], String)@, it adds the capability to control if the search must be done on enabled items or enabled and disabled items and if the tree must be expanded during the search to check non displayed items.


h2(#sirius5.0.0M6). Changes in Sirius 5.0.0M6

h3. User-Visible Changes

* <span class="label label-success">Added</span> An new _session editor_ is available on _.aird_ files. It provides an alternative, form-based GUI to visualize and manipulate sirius sessions which is not tied to the Modeling perspective or Model Explorer view. Sirius 5.0M6 includes a work-in-progress version of this new feature to encourage early community "feedback":https://wiki.eclipse.org/Sirius/SessionEditor. That version should be considered in alpha state in terms of stability an UI polish. By default, the new editor will automatically open when a session is opened, but this behavior can be disabled via a new preference in the _Sirius_ category.
* <span class="label label-info">Modified</span> The export diagram as images actions are now adapting the output resolution based on the diagram size, this leads to better resolution for small to medium diagrams (and also bigger file) and to an operation which is no longer failing with out of memory errors in case of very big diagrams.
* <span class="label label-info">Modified</span>The "straighten to" actions previously had a limitation concerning overlap detection. This is no longer the case. The previous known limitation was removed from the documentation (__In case of multi-selection, the overlap check is done in the current context of existing border nodes and not in the context of location of border nodes after each straighten edges.__).
* <span class="label label-info">Modified</span>Decorators on diagram elements are drawn over all figures. If there is an overlap between a decorator of a figure A and another figure B that is over figure A, when user clicks on the decorator, the figure B is now selected (before it was the parent figure A).

* <span class="label label-success">Added</span> It is now possible to create one or multiple pre-configured widget(s) in a group if its domain class and if the meta-models of the properties view containing it have been specified.
* <span class="label label-success">Added</span> Property Views definitions now support extending and overriding Properties View Descriptions without modifying the original. See "the documentation":specifier/properties/Properties_View_Description.html#extensibility_features for details.
* <span class="label label-info">Modified</span> The tab used to configure the metamodels used by the Properties view description is now using the same interface as the metamodels tab used to configure the representations.
* <span class="label label-info">Modified</span> The @package::Class@ syntax for domain classes and type names in the VSM is now fully supported and the new default. It means this syntax is interpreted by Sirius and completion is provided for it when the first @:@ character is entered. The legacy syntax @package.Class@ is still supported for compatibility.

h4. Changes in @org.eclipse.sirius@

* <span class="label label-info">Modified</span> The @org.eclipse.sirius.business.api.query.DViewQuery.getAllContentInRepresentations(Predicate<? super EObject>)@ now takes a @java.util.Predicate@ (from Java 8) as argument instead of a @com.google.common.base.Predicate@.
* <span class="label label-info">Modified</span> The extension point @org.eclipse.sirius.ui.modelingprojectresourcelistener@ is no longer expected to be used. It is an internal extension point. Clients using this extension point to ignore some files as potential semantic models must now use the extension point @org.eclipse.sirius.resourceStrategy@. This extension point existed before Sirius 5.0.0 but was not API. It becomes API with Sirius 5.0.0, see the "developer documentation":developer/extensions-provide_resource_strategy.html for more details.
** If you used to override protected methods @boolean isPotentialSemanticResource(IFile)@ and @boolean isLoadableModel(IFile, Session)@ of class @org.eclipse.sirius.ui.tools.api.views.modelexplorerview.resourcelistener.DefaultModelingProjectResourceListener@, you can now create a @resourceStrategy@ of type @org.eclipse.sirius.business.api.resource.strategy.ResourceStrategy.ResourceStrategyType.SEMANTIC_RESOURCE@ and respectively override @boolean isPotentialSemanticResource(URI)@ and @boolean isLoadableModel(URI,Session)@. As a reminder, to get an URI from an IFile, you can use: @URI.createPlatformResourceURI(iFile.getFullPath().toString(), true)@. And to get an IFile from an URI, you can use: @ResourcesPlugin.getWorkspace().getRoot().getFile(new Path(uri.toPlatformString(true)))@.
** If you used to override protected methods @boolean isRepresentationsModel(IFile)@ and @boolean isVsmModel(IFile)@ of class @org.eclipse.sirius.ui.tools.api.views.modelexplorerview.resourcelistener.DefaultModelingProjectResourceListener@, they no longer exist. They correspond to core API and is not supposed to be overridden. They are accessible through API @org.eclipse.sirius.business.api.query.FileQuery.FileQuery(IFile)@.
** All necessary classes for extension point @org.eclipse.sirius.resourceStrategy@ are now APIs:
*** @org.eclipse.sirius.business.api.resource.strategy.ResourceStrategyRegistry@: Registry to have access to all overridable services through a @ResourceStrategy@
*** @org.eclipse.sirius.business.api.resource.strategy.ResourceStrategy@: Interface implemented by all resource strategies
*** @org.eclipse.sirius.business.api.resource.strategy.AbstractResourceStrategyImpl@: Default implementation of above interface. All resource strategies contributed with the extension need to extend it.
*** @org.eclipse.sirius.business.api.resource.strategy.LegacyReleaseResourceStrategyImpl@ (previously named @DefaultResourceStrategyImpl@): A resource strategy with the code used before the optimization concerning the @org.eclipse.sirius.business.api.resource.strategy.ResourceStrategy.ResourceStrategyType.RELEASE_RESOURCE_AT_RESOURCESET_DISPOSE@. It is not used but can be quickly contributed by someone that want the previous behavior (before Sirius 4.0.0 M6).
* <span class="label label-danger">Removed</span> The already deprecated constructor of @org.eclipse.sirius.business.api.control.SiriusUncontrolCommand@ with signature @SiriusUncontrolCommand(EObject, boolean, IProgressMonitor)@ has been removed; instead, use the alternate constructor with an additional explicit @boolean shouldEndBySaving@ parameter (set it to @true@ to obtain the same behavior as the removed constructor).
* <span class="label label-danger">Removed</span> In @org.eclipse.sirius.business.api.dialect.DialectServices@, methods @canCreateIdentifier@ and @createIdentifier@ have been removed.
* <span class="label label-danger">Removed</span> The @org.eclipse.sirius.business.api.dialect.identifier@ package and all its content (@AbstractRepresentationElementIdentifier@ and @RepresentationElementIdentifier@) have been removed.

h4. Changes in @org.eclipse.sirius.ui@

* <span class="label label-success">Added</span> The method @org.eclipse.sirius.ui.business.api.dialect.DialectUIServices.refreshEditor(DialectEditor, IProgressMonitor)@ has been added to allow specifiers to do a full refresh of its dialect editor easily.
* <span class="label label-info">Modified</span> The method @org.eclipse.sirius.ui.tools.api.assist.TextContentProposalProvider.getContentContext(String, int)@ has been made protected instead of private to allow to use it for sub types.
* <span class="label label-info">Modified</span> The method @org.eclipse.sirius.ui.tools.api.assist.TextContentProposalProvider.removeDuplicatedProposals(List<ContentProposal>)@ has been made protected instead of private to allow to use it in sub types.
* <span class="label label-success">Added</span> The method @org.eclipse.sirius.ui.tools.api.color.VisualBindingManager.getDefaultFontWithRuntimeSizeAndFromLabelFormat(List<FontFormat>)@ has been added to allow to retrieve a font using the given format and the default Sirius font (arial) and the runtime height.
* <span class="label label-success">Added</span> The method @org.eclipse.sirius.ui.tools.api.color.VisualBindingManager.getFontFromNameAndLabelFormatAndWithDefaultSize(List<FontFormat>, String)@ has been added to allow to retrieve a font using the given format and the given font name and the runtime height.
* <span class="label label-info">Modified</span> The method @org.eclipse.sirius.ui.tools.api.project.ModelingProjectManager.createLocalRepresentationsFile(IProject, IProgressMonitor)@ has its return type changed from @void@ to @Session@ to allow callers to have access to the newly created session directly.
* <span class="label label-success">Added</span> The method @org.eclipse.sirius.ui.tools.api.wizards.page.ViewpointsSelectionWizardPage.setBrowserMinWidth(int)@ has been added to allow modification of the minimum width (with default value "0") of the browser part of the viewpoint selection wizard.
* <span class="label label-success">Added</span> The method @org.eclipse.sirius.ui.tools.api.wizards.page.ViewpointsSelectionWizardPage.setColumnWidthEquality(boolean)@ has been added to allow modification of column width equality (with default value "false") of the root composite of the viewpoint selection wizard.

* <span class="label label-success">Added</span> The method @org.eclipse.sirius.ui.tools.api.dialogs.AbstractExportRepresentationsAsImagesDialog.isExportDecorations()@ has been added to know if decorations are displayed in the exported image.


h4. Changes in @org.eclipse.sirius.diagram@

* <span class="label label-info">Moved</span> The method @org.eclipse.sirius.diagram.business.api.refresh.IRefreshOverride.aroundRefresh(DDiagram)@ has been moved to @org.eclipse.sirius.diagram.business.api.refresh.IRefreshExtension@ to unify methods handling refresh extension under one interface. 
* <span class="label label-info">Modified</span> The method @org.eclipse.sirius.diagram.business.api.refresh.IRefreshExtension.aroundRefresh(DDiagram)@ has been modified with a default behavior that is the one before introduction of the method to avoid breaking compatibility.
* <span class="label label-danger">Removed</span> The interface @org.eclipse.sirius.diagram.business.api.refresh.IRefreshOverride@ has been removed because its only method has been moved into @org.eclipse.sirius.diagram.business.api.refresh.IRefreshExtension@ interface
* <span class="label label-danger">Removed</span> The @org.eclipse.sirius.diagram.business.internal.dialect.identifier@ package and all its content (@DiagramIdenttifier@, @NodeIdentifier@, @EdgeIdentifier@, @NodeContainerIdentifier@, and @NodeStyleIdentifier@) have been removed.

h4. Changes in @org.eclipse.sirius.diagram.ui@

* <span class="label label-success">Added</span> The class @org.eclipse.sirius.diagram.ui.graphical.edit.policies.SiriusDecoratorEditPolicy@ has been added to improve the behavior of decorator selection.
* <span class="label label-success">Added</span> A new decoration mechanism has been implemented. Now, Sirius uses a single @IDecorator@ to decorate EditPart in diagram. That allows Sirius to manage the relative positioning between decorations.
** <span class="label label-success">Added</span> @org.eclipse.sirius.diagram.ui.tools.api.decoration.SiriusDecorationDescriptorProvider@ represents a provider able to give the decoration descriptors. @org.eclipse.sirius.diagram.ui.tools.api.decoration.AbstractSiriusDecorationDescriptorProvider@ is an abstract class that can be inherited to implement @SiriusDecorationDescriptorProvider@.
** <span class="label label-success">Added</span> @org.eclipse.sirius.diagram.ui.tools.api.decoration.DecorationDescriptor@ is a simple POJO that contains information needed to display decoration.
** <span class="label label-success">Added</span> @org.eclipse.sirius.diagram.ui.tools.api.decoration.SiriusDecorationProviderRegistry@ allows to register and get @SiriusDecorationDescriptorProvider@.
** <span class="label label-danger">Removed</span> @org.eclipse.sirius.diagram.ui.tools.api.decoration.AbstractSiriusDecorator@ is removed because now useless.
* <span class="label label-success">Added</span> The preference @SiriusDiagramUiPreferencesKeys.PREF_AUTHORIZE_DECORATION_OVERLAP@ has been added in @org.eclipse.sirius.diagram.ui.tools.api.preferences.SiriusDiagramUiPreferencesKeys@. If true, the overlap is authorized between decoration group on diagram element.
** <span class="label label-success">Added</span> The class @org.eclipse.sirius.diagram.ui.provider.DiagramUIPlugin.Implementation.DynamicDiagramUIPreferences@ and the method @org.eclipse.sirius.diagram.ui.provider.DiagramUIPlugin.Implementation.getDynamicPreferences()@ have been added to have good performances in getting the preference value.
* <span class="label label-info">Modified</span> The preference @SiriusDiagramUiPreferencesKeys.PREF_PRINT_DECORATION@ has been added in @org.eclipse.sirius.diagram.ui.tools.api.preferences.SiriusDiagramUiPreferencesKeys@. If true, the decorations of the diagram elements of a diagram will be printed, when printing a diagram.
* <span class="label label-info">Modified</span> The @org.eclipse.sirius.diagram.ui.tools.api.part.DiagramEditPartService.DiagramEditPartService@ class which can be used to export diagrams as images is now automatically adapting the output resolution for raster image based on maximum buffer size specified through the @plugin.propeties@ file of the @org.eclipse.sirius.diagram.ui@ plugin. This leads to a noticeable increase of the export image size (you can expect a 10 factor on small diagrams) and the method will no longer fail with OutOfMemory errors as bigger diagrams will lead to a lower output resolution. Implementers using this class can override the @DiagramEditPartService.getMaximumTotalSize()@ method to return their own limit or @DiagramEditPartService.getExportResolutionFactor(DiagramEditPart, SiriusDiagramImageGenerator)@ and return @1.0@ to get back to the previous behavior.
* <span class="label label-info">Moved</span> The methods of interface @org.eclipse.sirius.diagram.ui.tools.api.format.SiriusFormatDataManagerWithMapping@ that are @getFormatData(FormatDataKey, RepresentationElementMapping)@ and @addFormatData(FormatDataKey, RepresentationElementMapping, AbstractFormatData)@ have been moved into the interface @org.eclipse.sirius.diagram.ui.tools.api.format.SiriusFormatDataManager@ to reduce interface numbers for less complexity.
* <span class="label label-danger">Removed</span> The methods @getFormatData(FormatDataKey key)@ and @addFormatData(FormatDataKey key, AbstractFormatData formatData)@ have been removed from interface @org.eclipse.sirius.diagram.ui.tools.api.format.SiriusFormatDataManager@ because they were deprecated.
* <span class="label label-danger">Removed</span> The interface @org.eclipse.sirius.diagram.ui.tools.api.format.SiriusFormatDataManagerWithMapping@ has been removed because all its methods have been moved into interface @org.eclipse.sirius.diagram.ui.tools.api.format.SiriusFormatDataManager@

h4. Changes in @org.eclipse.sirius.tree.ui@

* <span class="label label-success">Added</span> The enum class for Sirius tree preferences @org.eclipse.sirius.tree.ui.tools.api.preferences.SiriusTreeUiPreferencesKeys@ has been added with the enum value @SiriusTreeUiPreferencesKeys.PREF_ALWAYS_USE_STANDARD_FONT_SIZE@. This enum value is the preference when true allowing to use runtime font height when displaying Sirius tree editor's items instead of the one specified in the VSM.

h4. Changes in @org.eclipse.sirius.properties.core@

* <span class="label label-success">Added</span> The class @org.eclipse.sirius.properties.core.internal.converter.ViewDescriptionConverter@ has been moved as an API to @org.eclipse.sirius.properties.core.api.ViewDescriptionConverter@.
* <span class="label label-success">Added</span> The classes necessary to support the preprocessing of the odesign for the inheritance in its Properties parts are available in the API package @org.eclipse.sirius.properties.core.api@.
* <span class="label label-success">Added</span> The class @org.eclipse.sirius.properties.core.internal.SiriusInterpreter@ has been moved as an API to @org.eclipse.sirius.properties.core.api.SiriusInterpreter@. This class could be used by those who want to create custom model operations using the Properties framework.
* <span class="label label-success">Added</span> The class @org.eclipse.sirius.properties.core.api.SiriusDomainClassTester@ has been added as an API for those who want to create custom model operations using the Properties framework.

h4. Changes in @org.eclipse.sirius.ui.properties@

* <span class="label label-info">Modified</span> All the content related to the IDescriptionConverter and ILinkResolver has been moved from the plugin org.eclipse.sirius.ui.properties to the newly created plugin org.eclipse.sirius.properties.core. It includes all the APIs and both extension points.

h4. Changes in @org.eclipse.sirius.editor.properties@

* <span class="label label-info">Modified</span> In the package @org.eclipse.sirius.editor.properties.sections.description.representationdescription@ the class @RepresentationDescriptionMetamodelsUpdater@ has been replaced by @DescriptionMetamodelsUpdater@ which can now be used with any EObject with a many-valued EReference to EPackages. The behavior of the class @RepresentationDescriptionMetamodelPropertySectionSpec@ has been transfered to an abstract class independent of @RepresentationDescription@ named @AbstractMetamodelPropertySectionSpec@. Those classes are now used for the edition of the metamodels of both the Properties view description and the various representations.
 

h4. Changes in @org.eclipse.sirius.ui@

* <span class="label label-success">Added</span> @org.eclipse.sirius.ui.business.api.dialect.DialectUIServices.export(DRepresentation, Session, IPath, ExportFormat, IProgressMonitor, boolean)@ method has been added. Compared to the previous method signature, the boolean parameter @exportDecorations@ has been added to allow to choose if the diagram element decorations will be exported or not.
* <span class="label label-info">Modified</span> The boolean parameter @exportDecorations@ has been added to @org.eclipse.sirius.ui.tools.api.actions.export.ExportAction.ExportAction(Session, Collection<DRepresentation>, IPath, ImageFileFormat, boolean, boolean)@ constructor. It allows to choose if the diagram element decorations will be exported or not.

h4. Changes in @org.eclipse.sirius.diagram@

* <span class="label label-success">Added</span> 
The utility class @org.eclipse.sirius.diagram.business.api.helper.decoration.DecorationHelper@ has been added. It provides @updateDecorations(List<Layer>)@ and @updateAllDecorations@ methods that allow to update only decorations in a diagram.

h4. Changes in @org.eclipse.sirius.tests.junit.support@

* <span class="label label-success">Added</span> The utility method @org.eclipse.sirius.tests.support.api.TestsUtil.setTargetPlatform()@ has been added to allow to load a PDE target platform according to all known OSGi bundles. It is useful to compile a plug-in in the execution runtime of the tests.
* <span class="label label-success">Added</span> The utility class @org.eclipse.sirius.tests.support.api.OpenedSessionsCondition@ has been extracted from a junit test to be used by multiple junit tests. It allows to wait until a session is in opened state.

h4. Changes in @org.eclipse.sirius.tests.swtbot.support@

* <span class="label label-success">Added</span> A new utility method @org.eclipse.sirius.tests.swtbot.support.api.editor.SWTBotSiriusDiagramEditor.dragCentered(String, Class<? extends EditPart>, int, int)@ improving the dragCentered method by adding the aimed Class in parameter.
* <span class="label label-info">Modified</span> A new AtomicBoolean parameter has been added to the utility method @mouseDragWithKey(int, int, int, int, int)@ in classes @org.eclipse.sirius.tests.swtbot.support.api.editor.SWTBotSiriusDiagramEditor@, @org.eclipse.sirius.tests.swtbot.support.api.editor.SWTBotSiriusGefViewer@ and @org.eclipse.sirius.tests.swtbot.support.api.widget.SWTBotSiriusFigureCanvas@. This allows to correctly wait the end of the drag'n'drop.
** Sample of code to use:
pre.. final AtomicBoolean dragFinished = new AtomicBoolean(false);
editor.dragWithKey(start.x, start.y, endpoint.x, endpoint.y, SWT.F3, dragFinished);
// Wait that the drag is done (the async Runnable simulating the
// drag)
bot.waitUntil(new ICondition() {
    @Override
    public boolean test() throws Exception {
        return dragFinished.get();
    }

    @Override
    public void init(SWTBot bot) {
    }

    @Override
    public String getFailureMessage() {
        return "The drag'n'drop operation has not finished.";
    }
});
// Wait that the figures are redrawn. In a fast environment, figures
// are not really redrawn and the rest of the test is not reliable.
SWTBotUtils.waitAllUiEvents();


h2(#sirius4.1.2). Changes in Sirius 4.1.2

h3. User-Visible Changes

* <span class="label label-success">Added</span> 
A new preference named _Maximum size of tabs name_ is available in the Sirius Properties View preference page. This preference is used to shorten the tabs names when the default rules are used to render the properties view.
!./images/PreferencePageMaxTabName.png! 

h3. Developer-Visible Changes

* <span class="label label-success">Added</span> @org.eclipse.sirius.diagram.ui.tools.api.format.SiriusFormatDataManagerWithMapping@ class has been added to handle copy/paste format with mapping information when an element target of a format pasting has many source diagram format corresponding to its key. In this case, we use the mapping information to get the more precise data format. And if no result matched, then we return the first found by using the key.

* <span class="label label-success">Added</span> @org.eclipse.sirius.diagram.ui.tools.api.format.SiriusFormatDataManagerWithMapping.getFormatData(FormatDataKey, RepresentationElementMapping)@ method has been added to retrieve during format pasting the data format corresponding to the given key and mapping when more than one result correspond to the key. If no result matches the mapping, then the first result found by using the key is returned.

* <span class="label label-success">Added</span> @org.eclipse.sirius.diagram.ui.tools.api.format.SiriusFormatDataManagerWithMapping.addFormatData(FormatDataKey, RepresentationElementMapping, AbstractFormatData)@ method has been added to allow data format manager to register data format with mapping information when copying format.

* <span class="label label-success">Deprecated</span>
@org.eclipse.sirius.diagram.ui.tools.api.format.SiriusFormatDataManager.getFormatData(FormatDataKey)@ It is replaced by @org.eclipse.sirius.diagram.ui.tools.api.format.SiriusFormatDataManagerWithMapping.getFormatData(FormatDataKey, RepresentationElementMapping)@ to better handle copy/paste format cases.

* <span class="label label-success">Deprecated</span>
@org.eclipse.sirius.diagram.ui.tools.api.format.SiriusFormatDataManager.addFormatData(FormatDataKey, AbstractFormatData)@ It is replaced by @org.eclipse.sirius.diagram.ui.tools.api.format.SiriusFormatDataManagerWithMapping.addFormatData(FormatDataKey, RepresentationElementMapping, AbstractFormatData)@ to better handle copy/paste format cases.

h2(#sirius4.1.1). Changes in Sirius 4.1.1

h3. User-Visible Changes

* <span class="label label-info">Modified</span>The "straighten to" actions were previously disabled when an edge is connected to border nodes that have several edges. It is now allowed.

h3. Developer-Visible Changes

* <span class="label label-success">Added</span> @org.eclipse.sirius.table.business.api.helper.TableHelper.getEStructuralFeature(DLine, DColumn)@ method has been added to retrieve the EStructuralFeature associated to a table column.

h2(#sirius4.1.0). Changes in Sirius 4.1.0

h3. User-Visible Changes

* <span class="label label-success">Added</span> Copy/Paste Layout has been completed with Copy/Paste Style and Copy/Paste Format. _Paste Format_ is equivalent to paste _Layout_ and _Style_ action. See chapter "_Copy/paste of format_":./user/diagrams/Diagrams.html#copy_paste_format in _User Manual_ for more details.
* <span class="label label-success">Added</span> The "snap to shape":./user/diagrams/Diagrams.html#snap_to_shapes feature is now available on border nodes.
* <span class="label label-success">Added</span> It is now possible to display an attachment link between an edge and its labels when label or edge is selected. This is not the default behavior but it can be activated by a preference in _Sirius/Sirius Diagram/Connections_ preference page. See chapter "_Display attachment link between edge and its labels_":./user/diagrams/Diagrams.html#edge_label_attachment in _User Manual_ for more details.
* <span class="label label-success">Added</span> It is now possible to straighten an edge to top, bottom, left or right. These actions are available on edge contextual menu _Layout/Straighten_. See chapter "_Straighten an edge_":./user/diagrams/Diagrams.html#straighten_an_edge in _User Manual_ for more details.
* <span class="label label-success">Added</span> It is now possible to disable the _Default_ and _Semantic_ properties tabs (visible when selecting and element from the _Model Explorer_ or from a Sirius editor, respectively) when using modelers which provide fully-functional replacements defined directly with Sirius. This is controled in the new _Sirius > Sirius Properties View_ preference page.
* <span class="label label-success">Added</span> Sirius-defined properties view are now enabled for semantic elements selected directly from inside the _Model Explorer_ (as long as the selected element is from inside an open Sirius session/project). Previously only elements selected from inside a Sirius editor were supported.
* <span class="label label-info">Modified</span> In the Sirius-provided _Properties View_, the edition of a text field is only taken into account when pressing _Enter_ or leaving the field. Previously it was triggered asynchronously after a small delay without activity, which could be confusing.
* <span class="label label-info">Modified</span> When trying to open a session which holds a representation resource or a VSP which was saved using a more recent version of Sirius than the one you are using, the session will be automatically closed displaying an error message. You can overload this behavior by providing you own implementation of @UICallBack@ in which you can have an UI feedback letting you choose if you want to open the session anyway. Warning: if you choose to proceed, there is no guarantee that the resulting session will be usable. It may even lead to data loss or corruption; use at your own risk.
If a viewpoint has been defined with a more recent version of Sirius than the one you are using, the @ViewpointRegistry@ will not register it and a warning is logged in the error log view to inform the user.
* <span class="label label-info">Modified</span> The "move edge group":./user/diagrams/Diagrams.html#move_edge_group feature now also work for a selection of edge group.
* <span class="label label-info">Modified</span> In a diagram editor, the zoom with mouse wheel is now zooming on mouse location instead of center of the editor. See "user documentation":./user/diagrams/Diagrams.html#zooming_diagram_id .
* <span class="label label-info">Modified</span> The direct edit on a Note or Text is now accessible by a slow double click like any other diagram element.
* <span class="label label-info">Modified</span> The shortcut _Ctrl+&_, for "_Reset Origin_":./user/diagrams/Diagrams.html#reset_origin action, has been replaced by _Ctrl+HOME_.

h3. Specifier-Visible Changes

* <span class="label label-success">Added</span> It is now possible to inline a copy of the default Properties Views model inside the VSM. This is a copy of the model Sirius would use if no _Properties View Description_ was specified. It can be used as a starting point for manual customization, or as a complement for elements for which you do not provide any custom rules. 
* <span class="label label-success">Added</span> In the definition of the Properties view, hyperlink and label widgets can now have widget actions.
* <span class="label label-success">Added</span> Hyperlink and label widgets now have a @displayExpression@, if blank the result of the value expression will be used after a call to the method @java.lang.Object#toString()@.
* <span class="label label-success">Added</span> Hyperlink and label widgets now support optional associated actions (visible as buttons on the right of the widget).
* <span class="label label-success">Added</span> A new widget named List with the same behavior as the multiple reference widget.
* <span class="label label-success">Added</span> _Page_ and _Group_ descriptions in _Properties View_ models now support a @preconditionExpression@, which behaves in the same way as preconditions for mappings on representation descriptions.
* <span class="label label-info">Modified</span> The rules concerning the layout of compartments have been changed/completed. You can have a look at the "dedicated chapter":specifier/diagrams/Diagrams.html#compartments_layout in the specifier documentation for more details.
* <span class="label label-info">Modified</span> In the VSM editor, all dialogs which ask for selecting elements from the VSM will now show the fully qualified path of each element, instead of just their name, to allow distinguishing elements with the same name appearing in different places.
* <span class="label label-info">Modified</span> The properties @fontSize@ and @labelFontSize@ have been renamed into @fontSizeExpression@ and @labelFontSizeExpression@ since both of them were already treated as expression.
* <span class="label label-info">Modified</span> In the VSM editor, the _Identifier_ attribute of many _Prroperties View_ related elements has been moved into the _Advanced_ tab and renamed _Extension Id_, as it is not actually required on common use cases but only for extensibility purposes.
* <span class="label label-info">Modified</span> The property @Domain Class Expression@ in @DynamicMappingFor@ elements (in properties views definitions) has been renamed into @Iterable Expression@.
* <span class="label label-info">Modified</span> The _Properties View_ widget which was named _Reference_ in Sirius 4.0 has been renamed as _List_, as it corresponds to an arbitrary list of elements with customizable buttons for acting on them. A new _Reference_ widget was added for handling plain _EReference_ edition with minimal configuration needed.
* <span class="label label-info">Modified</span> When opening a VSM, the editor now automatically expands the first few levels to immediatly reveal the interesting elements (representation descriptions).
* <span class="label label-warning">Deprecated</span> The extension point @org.eclipse.sirius.diagram.ui.layoutDataManager@ is deprecated. It is replaced by the new extension point @org.eclipse.sirius.diagram.ui.formatDataManager@. The deprecated extension point will be removed in the next 5.0 Sirius major release. Several classes associated with this deprecated extension point are also deprecated (see Developer-Visible Changes for details).

h3. Developer-Visible Changes

* <span class="label label-success">Added</span> As the first step to save the DRepresentation in its own resource, @org.eclipse.sirius.viewpoint.DView.getOwnedRepresentationDescriptors()@ has been added as a wrapper of the @DRepresentation@. The @DRepresentationDescriptor@ is contained by the @DView@ and the @DRepresentationDescriptor@ have a reference to the @DRepresentation@. In this step, the main impact is that the Sirius common navigator does not display the @DRepresentation@ anymore but the @DRepresentationDescriptor@ instead. All the actions and commands are then based on @DRepresentationDescriptor@.
* <span class="label label-success">Added</span> As the second step to save the DRepresentation in its own resource, @org.eclipse.sirius.viewpoint.DView.getOwnedRepresentations()@ has been removed. The @DRepresentation@ is now created as root element of the representations resource. The main impact is on the core of Sirius but also potentially on client Sirius customization. Each peace of code that makes the supposition that the @DView@ is the container of the @DRepresentation@ must be reworked. The code using methods in the following list may be concerned by the rework:
** @EObject.eContainer()@. If the object is a @DRepresentation@, its container is now null.
** @EcoreUtil.getRootContainer(xxx)@. The root container of a DDiagramElement is the @DRepresentation@ and not the @DAnalysis@ any more.
** @EcoreUtil.isAncestor(xxx)@. the @DView@ is not an ancestor of a @DRepresentation@ (or its content) anymore.
* <span class="label label-success">Added</span> As a developer, the followings utility methods will help you to migrate your code following the second step described above:
** @org.eclipse.sirius.business.api.query.DViewQuery.getLoadedRepresentations()@ replaces the removed @DView.getOwnedRepresentations()@ method. It provides all the loaded representations holds by a @DView@. In this step, all that representations are always loaded as they are into the .aird resource.
** @org.eclipse.sirius.business.api.query.DViewQuery.getAllContentInRepresentations(final Predicate<? super EObject>)@ provides the content of a @DView@ according to a predicate.
** @org.eclipse.sirius.business.api.query.DRepresentationQuery.getRepresentationDescriptor()@ provides the @DRepresentationDescriptor@ which references the @DRepresentation@.
** @org.eclipse.sirius.business.api.query.EObjectQuery.getDAnalysis()@ allows to retrieve a DAnalysis from a @DRepresentationElement@

h4. Changes in @org.eclipse.sirius@

* <span class="label label-success">Added</span> A new extension point named @org.eclipse.sirius.interpretedExpressionQueryProvider@ (with the associated new interface @org.eclipse.sirius.business.api.dialect.description.IInterpretedExpressionQueryProvider@) allows external contribution of @IInterpretedExpressionQuery@ specific to some particular expression occurrences in the VSM. This is used in particular for VSM extensions which do not fit well into the hard-coded assumptions about @IInterpretedExpressionQuery@. In Sirius 4.1, this is used to add completion and validation support for expressions used in properties views descriptions.
* <span class="label label-success">Added</span> @org.eclipse.sirius.business.api.migration.AirdResourceVersionMismatchException@ exception has been added to cancel Sirius session opening due to an .aird version mismatch, i.e. when one the of the loaded Representation resources is coming from a newer Sirius release.
* <span class="label label-success">Added</span> @org.eclipse.sirius.viewpoint.DView.getOwnedRepresentationDescriptors()@ has been added as the first step to save the DRepresentation in its own resource. In this step, the DRepresentationDescriptor life cycle is the same as the associated DRepresentation.
** @org.eclipse.sirius.business.api.dialect.command.RenameRepresentationCommand@
** @org.eclipse.sirius.business.api.dialect.command.DeleteRepresentationCommand@
** @org.eclipse.sirius.business.api.dialect.command.MoveRepresentationCommand@
** @org.eclipse.sirius.business.api.dialect.command.CopyRepresentationCommand@
* <span class="label label-success">Added</span> @getAvailableRepresentationDescriptions(Collection<Viewpoint>, EObject)@, @getAllRepresentationDescriptors(Session )@, @getRepresentationDescriptors(EObject, Session)@ and @getRepresentationDescriptors(RepresentationDescription, Session )@ have been added in @org.eclipse.sirius.business.api.dialect.DialectServices@ and implemented in @org.eclipse.sirius.business.api.dialect.AbstractRepresentationDialectServices@. These methods are used, instead of their equivalent with DRepresentation, for every functionality which relies on @DRepresentationDescriptor@ instead of @DRepresentation@ such as actions, wizards or views.
* <span class="label label-success">Added</span> @org.eclipse.sirius.business.api.dialect.AbstractRepresentationDialectServices.isSupported(DRepresentationDescriptor)@ has been added because actions, wizards or views that were related to @DRepresentation@ are now related to @DRepresentationDescriptor@.
* <span class="label label-success">Added</span> @org.eclipse.sirius.ui.business.api.dialect.DialectUIServices.canHandle(DRepresentationDescriptor)@ has been added because actions, wizards or views that were related to @DRepresentation@ are now related to @DRepresentationDescriptor@.
* <span class="label label-success">Added</span> @org.eclipse.sirius.ui.business.api.dialect.DialectUIManager.canExport(DRepresentationDescriptor, ExportFormat)@ has been added because actions, wizards or views that were related to @DRepresentation@ are now related to @DRepresentationDescriptor@.
* <span class="label label-success">Added</span> @org.eclipse.sirius.business.api.query.DRepresentationQuery.getRepresentationDescriptor()@ has been added to retrieve the @DRepresentationDescriptor@ that references the @DRepresentation@.
* <span class="label label-success">Added</span> @org.eclipse.sirius.business.api.session.CustomDataConstants.DREPRESENTATION_DESCRIPTOR_FROM_DESCRIPTION@ and @org.eclipse.sirius.business.api.session.CustomDataConstants.DREPRESENTATION_DESCRIPTOR@ have been added. They are used to get or put @DRepresentationDescriptor@ in the model managed by the @Session@ through the @org.eclipse.sirius.business.api.session.SessionService.putCustomData(String, EObject, EObject)@ and @SessionService.getCustomData(String, EObject)@ methods.
* <span class="label label-success">Added</span> @org.eclipse.sirius.business.api.query.EObjectQuery.getDAnalysis()@ has been added to retrieve a DAnalysis from a @DRepresentationElement@
* <span class="label label-info">Modified</span> @org.eclipse.sirius.business.api.session.danalysis.DAnalysisSessionHelper.findContainerForAddedRepresentation(DAnalysis, DRepresentation)@ has been changed to @findDViewForRepresentationDescription(DAnalysis , final RepresentationDescription)@ because that API was previously badly defined.
* <span class="label label-info">Modified</span> @org.eclipse.sirius.business.api.dialect.DialectServices.deleteRepresentation(DRepresentation, Session)@ has been changed to @deleteRepresentation(DRepresentationDescriptor, Session)@ because now the @DRepresentationDescriptor@ is the entry point to delete the @DRepresentation@ and itself.
* <span class="label label-info">Modified</span> @DRepresentationDescriptor@ is now the entry point to move, control or uncontrol a @DRepresentation@ instead of the @DRepresentation@ itself. Accordingly, the return type or parameter of the followings have changed to switch from @DRepresentation@ to @DRepresentationDescriptor@
** constructors of @org.eclipse.sirius.business.api.control.SiriusControlCommand@
** the constructor @org.eclipse.sirius.business.api.dialect.command.MoveRepresentationCommand.MoveRepresentationCommand(Session, DAnalysis, Collection<DRepresentationDescriptor>)@
** the method @org.eclipse.sirius.business.api.session.danalysis.DAnalysisSession.moveRepresentation(DAnalysis, DRepresentationDescriptor)@
* <span class="label label-info">Modified</span> @org.eclipse.sirius.business.api.session.danalysis.DAnalysisSessionHelper.updateModelsReferences(DView)@ has replaced @updateModelsReferences(DAnalysis, Iterator<DSemanticDecorator>)@ because it is more suited to the client needs.

h2(#sirius4.0.0). Changes in Sirius 4.0.0

h3. User-Visible Changes

* <span class="label label-success">Added</span> The user can now filter elements according to a Typed variable (String, Integer, EEnum or any EDataType). If a user applies a filter containing Typed Variables, a dialog is displayed to allow user entering the Typed Variable values. That values can be used as variables in the Condition Expression of the Variable Filter.
* <span class="label label-success">Added</span> When the diagram is larger than the editor, you can move it in all directions pressing the middle-button and dragging the mouse (keeping the button pressed).
* <span class="label label-info">Modified</span> Now if an object is locked and cannot be modified according to @IPermissionAuthority@, the properties view will not be editable if this locked object is selected from the Model Explorer view.
* <span class="label label-info">Modified</span> When trying to reconnect an edge end on another edge, the edge is now highlighted only if a reconnect tool is found (the precondition of the tool is not tested here).
* <span class="label label-info">Modified</span> List items now have the same margin whichever their parent is a simple list or a compartmentalized list. The margin in compartmentalized list was incorrectly set to 0 pixel.
* <span class="label label-info">Modified</span> The wizard to ask the new representation name has been changed. These concerns the title of the wizard and the input label. Example with a new Entities diagram for EcoreTools:
!images/representationNameWizardChange.png!
* <span class="label label-info">Modified</span> The export of diagram as image handles the gradient color for container background for BMP, JPG, PNG and SVG formats. Before, it only works for JPG format.
* <span class="label label-info">Modified</span> The <img src="images/ApplyAppearanceProperties.png" style="box-shadow:none;display:inline;margin:0px;padding:0px;"/> @Apply Appearance Properties@ action has been modified to use the last selected element as base style instead of the first one.

h3. Specifier-Visible Changes

* <span class="label label-success">Added</span> Sirius 4.0 introduces *experimental* support for specifying the properties views of your modelers directly from inside the VSM. This feature uses the same dynamic approach as for specifying diagrams, tables and trees, with a very flexible configuration language and no code generation involved (including live preview of any change). As of Sirius 4.0, this feature should be considered in an experimental state with details subject to changes until Sirius 4.1, and is not installed by default. To install it, make sure either "the Eclipse Neon repositry":http://download.eclipse.org/releases/neon or the "Sirius 4.0":http://download.eclipse.org/sirius/updates/releases/4.0.0/neon and "EEF 1.6":http://download.eclipse.org/modeling/emft/eef/updates/releases/1.6.0 repositories are available, and then to install the following features (from in the _Modeling_ category of Neon, or _Sirius Experimental Features_ of the Sirius repository ):
** _Sirius Properties Views - Runtime Support_ (@org.eclipse.sirius.properties.feature.feature.group@): needed at runtime for deployed modelers which have properties views defined in their specification.
** _Sirius Properties Views - Specifier Support_ (@org.eclipse.sirius.specifier.properties.feature.feature.group@): provides support for editing the configuration model directly inside the VSM editor and the specifier documentation.
Once this is done, you can find the actual documentation in the _Sirius Specifier Manual_, under the "_Properties View_":specifier/properties/Properties_View_Description.html section.
* <span class="label label-success">Added</span> All static strings defined in the VSMs which are visible to the end-user of the modeler, like viewpoint and tools names, can now be internationalized. Simply replace the name with a translation key reference of the form @%myUniqueKey@ in the VSM, and define the value in the _Viewpoint Specification Project_'s @plugin.properties@ (for the default value), or @plugin_XX.properties@ for locale @XX@. The underlying mechanism is the same as for Eclipse/OSGi plug-ins, so translations can even be contributed by physically separate plug-in fragments. See "the corresponding section":specifier/general/Specifying_Viewpoints.html#translatable_messages in the documentation for more details.
* <span class="label label-success">Added</span> It is possible to create "Typed Variable":specifier/diagrams/Diagrams.html#filter_with_typed_variable under Variable Filter.
* <span class="label label-success">Added</span> A new class @org.eclipse.sirius.ext.emf.edit.EditingDomainServices@ (from plug-in @org.eclipse.sirius.ext.emf.edit@) has been added with a complete set of service methods to leverage most of the features of the "EMF Edit" framework, for example the various _Item Providers_ associated to semantic elements. See "the documentation":specifier/general/Writing_Queries.html#editing_domain_services for details.
* <span class="label label-success">Added</span> The specifier can now restrict the border node authorized sides. This new option is available in the advanced tab of the border node style. See the "specifier documentation":specifier/diagrams/Diagrams.html#authorizedsides for more details.
* <span class="label label-info">Modified</span> The use of type literals in operations like @filter()@ or @oclIsKindOf()@ requires to explicitly add the domain meta-models plug-ins to the dependencies of the _Viewpoint Specification Project_. The documentation has been modified to recommend this.
* <span class="label label-info">Modified</span> *Warning*: Before this version, a style customization of an @EEnum@ attribute, like @labelFormat@, worked with a value expression using a Java service returning a @EEnumLiteral@. It is now forbidden. You must return an @Enumerator@. The documentation about "Styles Customization":specifier/diagrams/Diagrams.html#enum_customization now details this case.
* <span class="label label-info">Modified</span> The @BorderSizeComputationExpression@ migration has been corrected to recursively handle the sub container mappings. VSM created or migrated with Sirius 3.1.0, 3.1.1 or 3.1.2 might require a manual modification for the style descriptions of sub container mappings with border size computation equals to 0 as we cannot determine if they were added (or updated) after or before the migration: starting with Sirius 3.1.0, no border will be displayed for a 0 pixel value whereas with older version container always had at least a 1 pixel border.
* <span class="label label-info">Modified</span> The variable under VariableFilter, previously named "Variable", is renamed to "Select Model Element Variable". It is functionally equivalent.

h3. Developer-Visible Changes

* <span class="label label-success">Added</span> It is now possible to provide a full customized tab-bar by implementing the @ITabbarContributor@ through the @org.eclipse.sirius.diagram.ui.tabbarContributor@ extension-point. See the "developer documentation":developer/extensions-provide_tabbar_extensions.html#contributeFullTabbar for more details.
* <span class="label label-success">Added</span> It is now possible to provide new shapes for basic shape styles through the @org.eclipse.sirius.diagram.bundledImageShape@ extension-point. See the "developer documentation":developer/extensions-provide_custom_bundled_image_shape.html for more details.

This method now uses the description name as title for the wizard. This new method has been implemented by @org.eclipse.sirius.ui.tools.api.command.AbstractSWTCallback@ and @org.eclipse.sirius.tools.api.command.ui.NoUICallback@.
* <span class="label label-success">Added</span> @org.eclipse.sirius.ui.tools.api.project.ModelingProjectManager.loadAndOpenRepresentationsFile(URI, boolean)@ has been added to specify if job used to open a session must be considered as launched by the user or not, because by default with @ModelingProjectManager.loadAndOpenRepresentationsFile(URI)@ the job was not considered as launched by the user.

* <span class="label label-info">Modified</span> @org.eclipse.sirius.business.api.modelingproject.ModelingProject.getMainRepresentationsFileURI()@ methods no more update workspace resource about markers, now this must be done in caller on IllegalArgumentException catch in a workspace aware operation.
* <span class="label label-info">Modified</span> @org.eclipse.sirius.business.api.dialect.command.RefreshRepresentationsCommand.canExecute()@ now returns false if a @DRepresentation@ cannot be refreshed, by calling @DialectManager.canRefresh(DRepresentation)@.
* <span class="label label-info">Modified</span> Several methods of @org.eclipse.sirius.business.api.session.danalysis.DAnalysisSessionHelper@ now return a @fr.obeo.dsl.viewpoint.DView@ instead of a @fr.obeo.dsl.viewpoint.DRepresentationContainer@: * @findContainer(EObject, Viewpoint, Collection<DAnalysis>, DAnalysisSelector)@,
** @findContainerForAddedRepresentation(EObject, Viewpoint, Collection<DAnalysis>, DAnalysisSelector, DRepresentation)@,

h4. Changes in @org.eclipse.sirius.diagram.ui@

* <span class="label label-success">Added</span> A new system property named @org.eclipse.sirius.diagram.ui.svg.maxCacheSizeMB@ has been added. It can be used to tweak the maximum size (in megabytes) of pre-rendered SVG images to keep in cache. The default is 50, corresponding to 50MB of bitmaps of 4 8-bit channels. Increasing the limit can improve performance when using diagrams with a lot of SVG images, at the cost of increased memory usage.

* <span class="label label-danger">Removed</span> The @org.eclipse.sirius.ui@, and thus the whole @org.eclipse.sirius.runtime@ feature no longer depends on the JDT (technically the dependency towards @org.eclipse.jdt.core@ has been removed). If you need the JDT Core in your environment, you will need to add the dependency explicitly. The Sirius specification environment (@org.eclipse.sirius.editor@) still depends on PDE (and thus indirectly the JDT too).

h4. Changes in @org.eclipse.sirius.tests.junit.support@

* <span class="label label-success">Added</span> The class @org.eclipse.sirius.tests.support.api.DefaultTestMemento@ has been created. It help to simulate a real @IMemento@ for editor restoration.
* <span class="label label-success">Added</span> The method @SiriusTestCase.initViewpoint(String, Session, boolean)@ has been added to allow viewpoint activation without creating representations.
* <span class="label label-success">Added</span> The methods @initLoggers()@ and @disposeLoggers()@ of class @org.eclipse.sirius.tests.support.api.SiriusTestCase@ have now a protected visibility (instead of private) to allow subclasses to use this logger without all the @genericSetUp@ behavior.
* <span class="label label-warning">Deprecated</span> The method @SiriusTestCase.initViewpoint(String, Session, EObject)@ has been deprecated because the last parameter is useless to activate a viewpoint.

h4. Changes in @org.eclipse.sirius.tests.swtbot.support@

* <span class="label label-success">Added</span> The method @getTreeItem(final SWTBotTreeItem[], final String)@ has been added in @org.eclipse.sirius.tests.swtbot.support.utils@ to retrieve recursively a @SWTBotTreeItem@ in a @SWTBotTreeItem@ array.

* <span class="label label-info">Modified</span> A second @String@ parameter has been added to the method @org.eclipse.sirius.tests.swtbot.support.api.business.UILocalSession.newDiagramRepresentation(String, String)@. This parameter is the label of the representation description. It is necessary since the change of the wizard to ask the new representation name (see User-Visible Changes for detail).
* <span class="label label-info">Modified</span> A third @String@ parameter has been added to the constructor of @org.eclipse.sirius.tests.swtbot.support.api.business.UINewRepresentationBuilder@ for the same above reasons.
 
h4. Changes in @org.eclipse.sirius.common.xtext@

* <span class="label label-info">Modified</span> The dependency from @org.eclipse.sirius.common.xtext@ to the JDT plug-in @org.eclipse.jdt.core@ is now optional. If you need the JDT Core in your environment, you will need to add the dependency explicitly. The Sirius specification environment (@org.eclipse.sirius.editor@) still depends on PDE (and thus indirectly the JDT too).

* <span class="label label-success">Added</span> The method @bindCompletionProcessor(AbstractPropertySection, IAssistContentProvider, Text)@ has been added to the class @org.eclipse.sirius.editor.tools.api.assist.TypeContentProposalProvider@ to allow to bind a specific IAssistContentProvider to the text.

h2(#sirius3.1.0). Changes in Sirius 3.1.0

h3. User-Visible Changes

* <span class="label label-success">Added</span> A new feature allows to snap to all shapes (instead of just to snap to sibling shapes). The <kdb>F4</kdb> shortcut key activates this mode when you resize a node, move a node or move a bendpoint of an edge, see "the documentation":./user/diagrams/Diagrams.html#snap_to_shapes for details.
* <span class="label label-success">Added</span> A new feature allows to move the edge group (Edge, Label, Border Nodes) if the <kdb>F3</kdb> shortcut is pressed during the edge moving/dragging. This feature is only available for the case of edges with border node as source and target. See "documentation":./user/diagrams/Diagrams.html#move_edge_group for more details.
* <span class="label label-success">Added</span> The label of edges now stays as much as possible near the edge when it is moved.
Sample before Sirius 3.1:
!images/edgeLabelMoveBeforeSirius3.1.gif! 
Same sample since Sirius 3.1:
!images/edgeLabelMoveAfterSirius3.1.gif!
* <span class="label label-success">Added</span> It is now possible to collapse compartments using the handle visible on the following illustrations. The handle's position varies depending on the label alignment to avoid overlapping (depending on the list elements alignment for a list with an hidden label).
!images/compartments_collapse.png! 
!images/compartments_collapse2.png!
* <span class="label label-info">Modified</span> The _Snap to Grid_ and _Snap to Shapes_ features are now automatically disabled on Sequence diagrams. As indicated "in the user documentation":./user/sequences/Sequence%20Diagrams.html#introduction, to work correctly, Sirius sequence diagrams must have a tight control on where the graphical elements are placed on the diagram and on their synchronization with the underlying semantic model. Previously, the user had to explicitely disable the snap features.
* <span class="label label-info">Modified</span> The _Link with Editor_ behavior has changed. The link with editor was previously unidirectional from the Common Navigator (Model Explorer view or Project view) toward the active representation. Now, when selecting one or several elements in the representation, the corresponding semantic elements are selected in the Common Navigator.
* <span class="label label-info">Modified</span> The _Arrange Linked Bordered Nodes_ tabbar action has been renamed to _Arrange Linked Border Nodes_ as it is border nodes which are layouted and not bordered nodes.

h3. Specifier-Visible Changes

* <span class="label label-info">Modified</span> The _Acceleo Query Language_ (AQL) interpreter has been improved. AQL, and its support in Sirius, is no longer considered experimental, and instead is now the recommended query language to use for new VSMs. Improvements mostly concern better completion and validation, and more precise error reporting. In particular AQL expressions will now be able to display warnings and errors in the Interpreter view. The message displayed in the Interpreter view after an evaluation has also been improved to display the qualified name of the type of the value computed (@ePackageName::eClassName@). The improvements realized can be viewed by clicking on the image below (click to zoom).
!images/improvedsiriusinterpreter_thumbnail.png!:images/improvedsiriusinterpreter.png
* <span class="label label-info">Modified</span> Related to the previous point, the projects created by the _Viewpoint Specification Project_ wizard are now configured to use AQL by default (instead of Acceleo 3/MTL before). They depend on @org.eclipse.sirius.common.acceleo.aql@ instead of @org.eclipse.sirius.common.acceleo.mtl@, and do not have the Acceleo nature anymore (it is not needed by AQL). If you want to use another language in your queries, make sure you set the appropriate dependencies so that the Sirius support for that language will be present at runtime to interpret the queries.
* <span class="label label-info">Modified</span> The support for containers with vertical or horizontal _compartments_ on diagrams was introduced in Sirius 3.0.0 as an experimental feature. Several improvements and corrections have been done around the behaviors of this feature which is no longer considered experimental. Validation rules and tooltips in the VSM editor are here to help the specifier create a consistent mapping structure.
* <span class="label label-info">Modified</span> <span class="label label-info">Experimental</span> New, experimental support for recursive _compartments_ on diagrams: the _children presentation_ property of a _Container Mapping_, which is defined as a _compartment_ (its parent _ContainerMapping_ has a _VerticalStack_ or _HorizontalStack_ _children presentation_), can now also be set to _Vertical Stack_ and _Horizontal Stack_. It allows to define complex stacks of _compartments_ mixing both stack directions. While working reliably, this support is marked experimental in Sirius 3.1.0 as there are still some behaviors which do not behave as expected. If you make use of this feature, be aware that some details may still change in future releases, including 3.1.x maintenance releases.
* <span class="label label-info">Modified</span> You now really have the capability to set the @BorderSizeComputationExpression@ as 0 for style of @ContainerMapping@. Before Sirius 3.1.0, a size of 0 was interpreted as 1 at runtime. For compatibility reason, all existing @BorderSizeComputationExpression@ equals to 0 for style of @ContainerMapping@ are automatically set to 1 (ditto for results of this expression in representations file for container elements). For @ContainerMapping@, the default value of @BorderSizeComputationExpression@ for new style is now 1, except for _Worskpace Image_ where the value is 0.
* <span class="label label-info">Modified</span> The delete command availability computation has been changed. In case of a delete tool, the availability is now computed considering first the precondition of the tool and then the delete authorisation (using @IPermissionAuthority@) of the potential to delete objects. This is the reverse order of what was done before, and can have performance impacts if the precondition is slow. The specifier will to take care to ensure a good performance for the precondition expression of the delete tool.

h3. Developer-Visible Changes

h4. Partial support for internationalization

Sirius 3.1 introduces partial support for internationalization: all literal strings from the runtime part of Sirius are now externalized and can be localized by third parties by providing the appropriate "language packs" as OSGi fragments. Note that this does not concern the VSM editor's UI, the VSMs themselves, or the parts of the UI inherited from Eclipse/EMF/GEF/GMF and other libraries and frameworks used by Sirius.

Some API changes were required to enable this. While technically breaking changes if interpreting strictly the OSGi versioning rules, the major version number of the impacted bundles was not incremented as the changes only concern classes that should not impact the vast majority of users. Most breaking changes concern the plug-in/activator classes from each bundle. They are:
* <span class="label label-success">Added</span>@org.eclipse.sirius.diagram.layoutdata.LayoutDataPlugin@, a subclass of @org.eclipse.emf.common.EMFPlugin@ has been added. The corresponding OSGi bundle activator is the internal class @LayoutDataPlugin.Implementation@.

* <span class="label label-success">Added</span> The method @invokeMethodWithoutException@ has been added in class @org.eclipse.sirius.common.tools.api.util.ReflectionHelper@ to call a private method. This method returns true (and not the result of the method) if it is called without exception. It returns false otherwise. Warning: This method must be used carefully.

* <span class="label label-success">Added</span> The new interface @org.eclipse.sirius.common.tools.api.interpreter.IInterpreterWithDiagnostic@ has been added. It allows an interpreter to evaluate an expression and return not only the result of the evaluation but also a diagnostic.
* <span class="label label-success">Added</span> The new class @org.eclipse.sirius.common.tools.api.contentassist.ContentProposalWithReplacement@ has been added. It allows interpreters to provide proposals for the code completion which can replace an existing part of the expression used. This behavior can be used if the user has started to type a value that would be returned by the code completion. For example, if the user types @aql:self.na@ and if he selects the content proposal @name@, it can replace the existing part of the expression @na@ to write @aql:self.name@ instead of just appending @name@ to create @aql:self.naname@.
* <span class="label label-success">Added</span> The new class @org.eclipse.sirius.common.tools.api.contentassist.ContentProposalBuilder@ used to build the content proposals with their various parameters more easily.

* <span class="label label-info">Modified</span> @org.eclipse.sirius.tools.api.command.DCommand@ no longer inherits from @IUndoableCommand@ since undo/redo is managed by EMF Transaction.
* <span class="label label-warning">Deprecated</span> @org.eclipse.sirius.business.api.componentization.ViewpointRegistryImpl.addSiriusFileCollector()@ method has been deprecated as it is about @ViewpointFileCollector@ and not @SiriusFileCollector@.
