		<h2 id="sirius6.3.0">Changes in Sirius 6.3.0</h2>
		<h3 id="DeveloperVisibleChanges">Developer-Visible Changes</h3>
		<h4 id="Changesinorg.eclipse.sirius">Changes in  
			<code>org.eclipse.sirius</code>
		</h4>
		<ul>
			<li><span class="label label-success">Added</span> A new EAttribute 
				<code>changeId</code> has been added in 
				<code>DRepresentationDescriptor</code>. It allows to know if two 
				<code>DRepresentation</code>(each associated to one DRepresentationDescriptor) are the same and have the exact same content. It can be useful to not load the representation if not needed. The methods 
				<code>updateChangeId(DRepresentationDescriptor)</code> and 
				<code>areRepresentationIdentical(DRepresentationDescriptor, DRepresentationDescriptor)</code> have been added in 
				<code>org.eclipse.sirius.business.api.helper.RepresentationHelper</code> to get change id information and to update it if needed in DRepresentationDescriptor.
			</li>
		</ul>
		<p>In case of migration the method 
			<code>org.eclipse.sirius.business.api.migration.AbstractRepresentationsFileMigrationParticipant.updateChangeId(DAnalysis, DRepresentation)</code> is available to update change id. New migration participants created after this Sirius version must update the change id of the DRepresentationDescriptor of the DRepresentation they change. The API to do that is described in MigrationParticpant 
			<a href="developer/extensions-provide_migrate_contribution.html#MigrationParticipantsImplem">documentation:</a> .
		</p>
		<ul>
			<li><span class="label label-success">Added</span>The method 
				<code>org.eclipse.sirius.business.api.query.DViewQuery.getLoadedRepresentationsDescriptors()</code> has been added and allows to retrieve all loaded 
				<code>DRepresentationDescriptor</code> in a 
				<code>DView</code>.
			</li>
		</ul>
		<ul>
			<li><span class="label label-info">Modified</span>The method 
				<code>org.eclipse.sirius.business.api.dialect.AbstractRepresentationDialectServices.copyRepresentation(DRepresentation, String, Session, IProgressMonitor)</code> has its first parameter changed from 
				<code>DRepresentation</code> to 
				<code>DRepresentationDescriptor</code>. Also the constructor of 
				<code>org.eclipse.sirius.business.api.dialect.command.CopyRepresentationCommand</code> has been modified. Its parameter 
				<code>Collection&lt;DRepresentation&gt; representations</code> has been replaced by 
				<code>Collection&lt;DRepresentationDescriptor&gt; representationDescriptors</code>. Theses changes were made  to be able to copy the name that is now only in 
				<code>DRepresentationDescriptor</code>.
			</li>
		</ul>
		<ul>
			<li><span class="label label-danger">Removed</span> In 
				<code>org.eclipse.sirius.business.api.session.CustomDataConstants</code>, the constants 
				<code>DREPRESENTATION</code> and 
				<code>DREPRESENTATION_DESCRIPTOR</code> has been removed because they are not available anymore in custom data.
			</li>
		</ul>
		<h2 id="sirius6.2.2">Changes in Sirius 6.2.2</h2>
		<p>There are no user-visible changes in Sirius 6.2.2 compared to 6.2.1. The only changes are internal and related either to the build process or to the automated tests.</p>
		<h2 id="sirius6.2.1">Changes in Sirius 6.2.1</h2>
		<h3 id="DeveloperVisibleChanges2">Developer-Visible Changes</h3>
		<h4 id="Changesinorg.eclipse.sirius2">Changes in  
			<code>org.eclipse.sirius</code>
		</h4>
		<ul>
			<li><span class="label label-success">Added</span> Added a constructor 
				<code>org.eclipse.sirius.business.api.query.DRepresentationQuery.DRepresentationQuery(DRepresentation, Session)</code> to compute queries directly from the given session instead of computing it.
			</li>
			<li><span class="label label-success">Added</span> In 
				<code>viewpoint.ecore</code>, the 
				<code>UIState</code> class has a new 
				<code>subDiagramDecorationDescriptors</code> attribute. It is used as a cache to speed up sub diagram decorations computing.
			</li>
			<li><span class="label label-success">Added</span> It is now possible to consider that some specific graphical changes need a refresh of the representation. Before Sirius 6.1.3, only semantic changes triggers a refresh. Now you can use 
				<code>RefreshHelper.registerImpactingNotification(Predicate&lt;Notification&gt;)</code> to consider a specific graphical changes. An example is the possibility to launch a refresh when the region container is collapsed or expanded. See 
				<a href="developer/trigger-refresh-graphical-changes.html">Trigger a Sirius refresh on specific graphical changes</a> in the developer documentation for more details.
			</li>
			<li><span class="label label-success">Added</span> The method 
				<code>org.eclipse.sirius.tools.api.ui.RefreshHelper.isAutoRefresh()</code> has been added to know if Sirius is in automatic refresh mode or in manual mode.
			</li>
			<li><span class="label label-success">Added</span> The methods 
				<code>org.eclipse.sirius.tools.api.ui.RefreshHelper.registerImpactingNotification(Predicate&lt;Notification&gt;)</code> and 
				<code>org.eclipse.sirius.tools.api.ui.RefreshHelper.unregisterImpactingNotification(Predicate&lt;Notification&gt;)</code> have been added to allow to consider some graphical modifications as requiring a refresh. By default, only semantic changes are considered as requiring a refresh.  
			</li>
			<li><span class="label label-danger">Removed</span> The 
				<code>org.eclipse.sirius.business.api.helper.task.NotificationTask</code> class has been removed. It was not used anywhere.
			</li>
		</ul>
		<h4 id="Changesinorg.eclipse.sirius.diagram.ui">Changes in  
			<code>org.eclipse.sirius.diagram.ui</code>
		</h4>
		<ul>
			<li><span class="label label-info">Modified</span> The 
				<code>org.eclipse.sirius.diagram.ui.business.api.image.ImageSelector.IMAGES_RESOURCE_NAME</code> constant has been deprecated. It was present in the initial commit of Sirius but has never been used in its open source components.
			</li>
		</ul>
		<h4 id="Changesinorg.eclipse.sirius.tests.swtbot.support">Changes in  
			<code>org.eclipse.sirius.tests.swtbot.support</code>
		</h4>
		<ul>
			<li><span class="label label-success">Added</span>  The methods 
				<code>org.eclipse.sirius.tests.swtbot.support.api.widget.SWTBotSiriusFigureCanvas.mouseMoveLeftClick(int, int, boolean, int[])</code>,

			<li><span class="label label-success">Added</span>  The method 
				<code>org.eclipse.sirius.tests.swtbot.support.api.editor.SWTBotSiriusHelper.selectPropertyTabItem(String, SWTBot)</code> has been added. It allows to look for property tab from a given bot. The bot corresponding to the property view should be given otherwise the search could fail starting from Eclipse 2019-06.
			</li>
		</ul>
		<ul>
			<li><span class="label label-success">Added</span>The method 
				<code>org.eclipse.sirius.tests.swtbot.support.api.editor.SWTBotSiriusHelper.getShellBot(String)</code> has been added and allows to retrieve a bot related to a shell with the given label.
			</li>

		<h3 id="UserVisibleChanges">User-Visible Changes</h3>
		<ul>
			<li><span class="label label-success">Added</span> On sequence diagrams, it is now possible to remove vertical blank spaces on standard edition mode by dragging the mouse from bottom to top anywhere in the canvas with the Ctrl+Shift keys pressed. This 
				<a href="user/sequences/Sequence%20Diagrams.html#remove_vertical_blank_space">feature</a> was here since version 6.0.0 but was only accessible through the ruler.
			</li>
		</ul>
		<h3 id="SpecifierVisibleChanges">Specifier-Visible Changes</h3>
		<ul>
			<li><span class="label label-success">Added</span> It is now possible to add action/group in the &#8220;New&#8221; contextual menu of diagram elements. This menu was missed in Sirius 6.1.0. It is now documented in the 
				<a href="specifier/diagrams/Diagrams.html#group">corresponding documentation</a> .
			</li>
		</ul>
		<h3 id="DeveloperVisibleChanges3">Developer-Visible Changes</h3>
		<h4 id="Changesinorg.eclipse.sirius.common">Changes in 
			<code>org.eclipse.sirius.common</code>
		</h4>
		<ul>
			<li><span class="label label-success">Added</span> A new interface 
				<code>org.eclipse.sirius.common.tools.api.interpreter.IConverter</code> has been added: it encapsulates the coercion rules used to convert raw results returned by interpreted expressions into the types expected by Sirius (depending on the context of use of the expression).
			</li>
			<li><span class="label label-success">Added</span> In interface 
				<code>org.eclipse.sirius.common.tools.api.interpreter.IInterpreter</code>, a new method 
				<code>getConverter()</code> has been added to obtain the 
				<code>IConverter</code> for a given interpreter.
			</li>
			<li><span class="label label-success">Added</span> A new class 
				<code>org.eclipse.sirius.common.tools.api.interpreter.EvaluationResult</code> has been added. It serves as a default implementation of 
				<code>IEvaluationResult</code>. It provides static factory methods for common cases (successful evaluation or failure).
			</li>
			<li><span class="label label-info">Modified</span> In 
				<code>org.eclipse.sirius.common.tools.api.interpreter.TypeName</code>, the methods 
				<code>getJavaClass()</code> and 
				<code>getPackagePrefix()</code> which used to return a 
				<code>org.eclipse.sirius.ext.base.Option&lt;T&gt;</code> now return standard 
				<code>java.util.Optional&lt;T&gt;</code> instead.
			</li>
			<li><span class="label label-info">Modified</span> In 
				<code>org.eclipse.sirius.common.tools.api.profiler.ProfilerTaskRegistry</code>, the method 
				<code>get(String)</code> which used to return a 
				<code>org.eclipse.sirius.ext.base.Option&lt;T&gt;</code> now return standard 
				<code>java.util.Optional&lt;T&gt;</code> instead.

				<code>getAdapter(Class&lt;?&gt;)</code> which used to return a 
				<code>org.eclipse.sirius.ext.base.Option&lt;T&gt;</code> now return standard

				<code>java.util.Optional&lt;T&gt;</code> instead.
			</li>
			<li><span class="label label-info">Modified</span> In 
				<code>org.eclipse.sirius.common.tools.api.util.ReflectionHelper</code>, all the following methods which used to return a 
				<code>org.eclipse.sirius.ext.base.Option&lt;T&gt;</code> now return standard 
				<code>java.util.Optional&lt;T&gt;</code> instead: 
				<code>setConstructorVisibleWithoutException(Class&lt;? extends Object&gt;, Class&lt;?&gt;...)</code>

		<ul>
			<li><span class="label label-info">Modified</span> The interface 
				<code>org.eclipse.sirius.common.tools.api.interpreter.IInterpreterWithDiagnostic.IEvaluationResult</code> has been promoted as a top-level type as 
				<code>org.eclipse.sirius.common.tools.api.interpreter.IEvaluationResult</code>. In the process it has gained several methods to check for success and coerce the raw evaluation result into any of the types that are used by Sirius (depending on the usage context).

				<code>org.eclipse.sirius.common.tools.api.interpreter.IInterpreter</code> (and all its implementations shipped with Sirius), the methods 
				<code>addVariableStatusListener()</code> and 
				<code>removeVariableStatusListener()</code> have been removed, along with the corresponding type 
				<code>org.eclipse.sirius.common.tools.api.interpreter.IVariableStatusListener</code>. These correspond to obsolete and unused mechanisms.
			</li>
			<li><span class="label label-danger">Removed</span> The 
				<code>interface org.eclipse.sirius.common.tools.api.interpreter.IInterpreterWithDiagnostic</code> has been removed. The single method it defined, 
				<code>evaluateExpression()</code>, is now implemented directly by the main

If at least one label is detected as &#8220;corrupted label&#8221;, the layout is also potentially corrupted (nodes, children of the diagram, with x or y coordinate very big). In this case, the concerned nodes are moved near 5000 (or -5000) as new coordinate. A message is added in this case: 
				<em>Some nodes have also been moved as the layout of this diagram is corrupted. A Reset Origin and/or manual layout is probably needed for this diagram.</em> The rules applied to detect a corrupted label are the following:
				<ul>
					<li>If the label is less than 250 pixels away from the reference point on its corresponding edge, the label is not considered as distant.</li>
					<li>If the label is more than 1000 pixels away from the reference point on its corresponding edge, the label is considered as distant.</li>

		<ul>
			<li><span class="label label-success">Added</span> 
				<code>org.eclipse.sirius.common.tools.api.util.LazyCrossReferencer.setEObjectToBeIgnored(Predicate&lt;EObject&gt;)</code> has  been added to filter inverse references to prevent some references resolution.
			</li>
			<li><span class="label label-info">Modified</span> 
				<code>org.eclipse.sirius.common.tools.api.util.WorkspaceUtil.getFilesFromWorkspace(Collection&lt;IProject&gt;, String)</code> signature has been modified in

		</h4>
		<ul>
			<li><span class="label label-success">Added</span> A new query has been added in 
				<code>org.eclipse.sirius.diagram.business.api.query.DDiagramQuery</code>. This query, 
				<code>getAllActivatedLayers</code>, returns all the activated layers (transient or not) of the given diagram. It should replace 
				<code>DDiagram.getActivatedLayers</code> in several cases if you directly use it.
			</li>
		</ul>
		<h4 id="Changesinorg.eclipse.sirius.diagram.ui7">Changes in 
			<code>org.eclipse.sirius.diagram.ui</code>
		</h4>
		<ul>
			<li><span class="label label-success">Added</span> Three new preferences have been added to 
				<code>org.eclipse.sirius.diagram.ui.tools.api.preferences.SiriusDiagramUiPreferencesKeys</code>: 
				<code>PREF_SCALE_DIAGRAMS_ON_EXPORT</code>, 
				<code>PREF_MAXIMUM_EXPORT_BUFFER_SIZE</code>, 
				<code>PREF_MAXIMUM_EXPORT_BUFFER_SIZE_WINDOWS</code>. They are used to control the auto-scaling behavior when exporting diagrams. Refer to the JavaDoc for the details.
			</li>
			<li><span class="label label-success">Added</span> In 
				<code>org.eclipse.sirius.diagram.ui.tools.api.part.DiagramEditPartService</code>, two new methods have been added:
				<ul>
					<li>
						<code>setAllowDownScaling(boolean)</code>: when auto-scaling is enabled (which is controlled by the already existing 
						<code>setAutoScalingEnabled()</code>), this is used to control if down-scaling is allowed or not. 
					</li>
					<li>
						<code>getScalingFactor()</code>: after the export has been performed, this can be used to obtain the scaling factor that was effectively used.
					</li>
				</ul>
			</li>
			<li><span class="label label-success">Added</span> The class 
				<code>org.eclipse.sirius.diagram.ui.business.api.DiagramExportResult</code> has been added, which inherits from 
				<code>ExportResult</code>. It is returned by the 
				<code>DialectManager.exportWithResult()</code> methods when the representation exported is a diagram, and in addition to the information provided by 
				<code>ExportResult</code> gives access to the scaling factor that was used when exporting the diagram.
			</li>
			<li><span class="label label-success">Added</span> The new preference 
				<code>org.eclipse.sirius.diagram.ui.tools.api.preferences.SiriusDiagramUiPreferencesKeys.PREF_SHOW_SYNCHRONIZE_STATUS_DECORATOR</code> has been added to say if the 
				<a href="user/diagrams/Diagrams.html#synchronized_diagram">synchronize status</a> decorator must be shown or not.
			</li>
			<li><span class="label label-success">Added</span> A new method 
				<code>checkShapesIntersect()</code> has been added in 
				<code>org.eclipse.sirius.diagram.ui.business.api.query.ConnectionEditPartQuery</code> to check if source and target of the connection intersect (only intersect &#8211; not one contained in another).
			</li>
		</ul>
		<h4 id="Changesinorg.eclipse.sirius.ext.emf.edit">Changes in 
			<code>org.eclipse.sirius.ext.emf.edit</code>
		</h4>
		<ul>
			<li><span class="label label-info">Modified</span> 
				<code>org.eclipse.sirius.ext.emf.edit.EditingDomainServices</code> does not use 
				<code>Collection</code> anymore as return type or parameter type in its services. 
				<code>java.util.Collection</code> has been replaced by 
				<code>java.util.List</code>. As mentioned in the 
				<a href="./specifier/general/Writing_Queries.html#service_methods">specifier documentation</a>, it is recommended to use List or Set instead of Collection in java services signature.
			</li>
		</ul>
		<h4 id="Changesinorg.eclipse.sirius.ui4">Changes in 
			<code>org.eclipse.sirius.ui</code>
		</h4>
		<ul>
			<li><span class="label label-success">Added</span> In 
				<code>org.eclipse.sirius.ui.tools.api.dialogs.AbstractExportRepresentationsAsImagesDialog</code> a new method 
				<code>isAutoScaleDiagram()</code> has been added to indicate (once the dialog has been closed) if the user has requested to enable auto-scaling on diagram export. 
			</li>
			<li><span class="label label-success">Added</span> In 
				<code>org.eclipse.sirius.ui.tools.api.actions.export.ExportAction</code>, a new method 
				<code>setAutoScaleDiagram(boolean)</code> to ask for automatic scaling of diagrams on export.
			</li>
			<li><span class="label label-success">Added</span> In 
				<code>org.eclipse.sirius.ui.business.api.dialect.DialectUIServices</code>, two new methods 
				<code>exportWithResult()</code> have been added. They are equivalent to the existing 
				<code>export()</code> methods (which return 
				<code>void</code>) except that they return an instance of the new type 
				<code>org.eclipse.sirius.ui.business.api.dialect.ExportResult</code>. This gives access to the list of all the actual files produced by the export operation. Note that in the case of the diagram dialect, 
				<code>exportWithResult()</code> actually returns a more specific 
				<code>DiagramExportResult</code> with additional diagram-specific information.
			</li>
			<li><span class="label label-success">Added</span> The type 
				<code>org.eclipse.sirius.ui.business.api.dialect.ExportFormat</code> has a new attribute representing the scaling policy to use for diagram. It is defined by a new enumerated type 
				<code>ExportFormat.ScalingPolicy</code> which can have four different values: 
				<code>WORKSPACE_DEFAULT</code>, 
				<code>AUTO_SCALING</code>, 
				<code>NO_SCALING</code>, 
				<code>AUTO_SCALING_IF_LARGER</code>. Refer to the JavaDoc for details on their meanings.
			</li>
			<li><span class="label label-success">Added</span> 
				<code>org.eclipse.sirius.ui.tools.api.wizards.CreateEMFModelWizard</code> is a new wizard that can be invoked to create instances of any metamodel. It will ask the end-user for a metamodel (
				<code>EPackage</code>), a concrete type to instanciate as root element, and finally the local path of the file to create. See the class Javadoc for sample usage. Note that the first two pages of the wizard (EPackage and root type selection) can be customized through the 
				<code>org.eclipse.sirius.common.package_meta_data</code> extension point to provide user-oriented name and documentation for an EPackage, and to suggest specific EClasses as good root candidates.
			</li>
			<li><span class="label label-success">Added</span> 
				<code>org.eclipse.sirius.ui.tools.api.command.AbstractSWTCallback.shouldDeleteRepresentation(Set&lt;DRepresentationDescriptor&gt;)</code> default implementation has been added to prompt the confirm dialog.
			</li>
			<li><span class="label label-success">Added</span> 
				<code>org.eclipse.sirius.ui.business.api.session.SessionEditorInput.SessionEditorInput(URI, URI, String, Session)</code> has been added to provide the 
				<code>DRepresentationDescriptor</code> URI to retrieve the 
				<code>DRepresentation</code> from the 
				<code>DRepresentationDescriptor.getRepresentation()</code> method instead of performing a direct load.
			</li>
			<li><span class="label label-info">Modified</span> The org.eclipse.sirius.ui.tools.api.assist.TextContentProposalProvider.getSelectedElement() method is now protected instead of private to let sub-classes retrieving the selected element.</li>

		<h4 id="Changesinorg.eclipse.sirius.ui.editor2">Changes in 
			<code>org.eclipse.sirius.ui.editor</code>
		</h4>
		<ul>
			<li><span class="label label-success">Added</span> New classes have been added in package 
				<code>org.eclipse.sirius.ui.editor.api.pages</code>. They are the following: 
				<code>AbstractSessionEditorPage</code>, 
				<code>PageProvider</code>, 
				<code>PageUpdateCOmmand</code>, 
				<code>PositioningKind</code>, 
				<code>PageUpdateCommandFactory</code>. These classes allow to provide custom pages to session editor instances.
			</li>
			<li><span class="label label-success">Added</span> An extension point 
				<code>org.eclipse.sirius.ui.editor.sessionEditorPageProvider</code> has been added to allow custom page providing for session editor instances.
