<td class="content">Renaming the Graphiti project from
modeling.gmp.graphiti to modeling.graphiti has been finalized. The
rename was needed because of the elimination of all container
projects in the modeling project. For Graphiti the former container
project GMP has been deleted; Graphiti is now i direct subproject of
the modeling main project. This change affected the name of the Git
repository, Wiki locations, build job names and our Bugzilla
component. For details see the bug.</td>

412858 </a></td>
<td class="content">An error in the update feature handling has
been found that can only be fixed in a potentially incompatible way.
In some situations the method <i>canUpdate</i> was not consulted
before calling the method <i>updateNeeded</i>. In order not to break
any existing tools relying on the current erroneous behavior, only a
first step to fix this bug was undertaken. From now on a Eclipse
error log entry will be written whenever a tool returns false on <i>canUpdate</i>
but returns a <i>true</i> update reason for calling <i>updateNeeded</i>.
This allows tool to continue to use their current implementation
until the actual bug in the Graphiti framework will be fixed in the
next development cycle for Eclipse Mars (probably Graphiti 0.12.0).
More detail on the fix and the error message can be found in the
linked Bugzilla (the fix is described in <a
href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=412858#c3">comment
3</a>, the error message in <a

angle is more precise</a></td>
<td class="content">The <i>angle</i> attribute that was used for
rotation of text graphics algorithms was stored as an integer which
lead to rounding issues and imprecise rendering. The <i>angle</i>
attribute has been deprecated and replaced by a <i>rotation</i>
attribute of type double. The framework internally cares about
compatibility with old diagrams by reading the old <i>angel</i>
attribute and storing it in the <i>rotation</i> attribute. Both <i>getAngle()</i>
and <i>getRotation()</i> methods on the graphics algorithms return
the value of the <i>rotation</i> field (in case of <i>getAngle()</i>
rounded to integer).

<td class="content">Clients are now more flexible in how they
can influence the update behavior by overriding <i>DefaultUpdateBehavior</i>:
the update adapter caring about updating to new file contents can
now be changed by clients. Also two bugs in the registration of the
update adapter (duplicate registration for initial resources) and
only reacting to the deletion of the first diagram in a resource to
close the editor were fixed.

functionality is not available. The contributor tried to add the
Graphiti save as image menu entry right after the Eclipse export
entry which caused an <i>IllegalArgumentException</i> in case it was
not available. The situation is now checked and the entry is only
added in case we find the location. Clients may override the new
method <i>addSaveAsImageEntryToMenu()</i> to define their own
location for the menu entry.
