−
**<code>attributeChanged()</code> Anything that needs to be saved must be in attribute form and passed to this method.

Utility method createTextField() handles this call. 
+
−
** <code>createLabel()</code> Utility method  added. It will put an '*' at the front of the label if the attribute has been modified. Eventually this will be applied upon editing but currently only happens after re-freshing or re-opening the editor.
+
−
** <code>SECTION_NAME</code> is an enum that holds default titles for the default sections. To override these default titles, set the appropriate (SECTION_NAME, new name) in <code>alternateSectionLabels</code> on <code>AbstractRepositoryTaskEditor</code>.

General

Mylyn follows the Eclipse conventions for version numbering and guarantees binary backwards compatibility for minor releases. Internals are binary backwards compatible between service releases.

API enhancements can be tracked by searching the source code for the corresponding @since JavaDoc tags or by querying for bugs that have [api] in their summary.

Changes in 3.22

  • Connectors that do not provide a task key no longer have their task ID automatically used as the key. Connectors that rely on this behaviour should explicitly set the task key to the ID. This change actually occurred in Mylyn 3.21 but was not added to this page until the 3.22 release.

Changes in 3.20

  • AbstractTaskListMigrator and its related extension point have been deprecated. Contributed migrators will no longer be applied when loading the Task List (bug 493037).

Changes in 3.12

Changes in 3.11

Changes in 3.10

None.

Porting from 3.8 to 3.9

Mylyn Reviews

The Reviews framework has had a major update which resulted in changes to the core model and API. In consequence, the version was updated to 2.0.

Porting from 3.7 to 3.8

No API changes that affect integrators.

Porting from 3.6 to 3.7

Mylyn Commons

  • bug 305782 Restructuring of Mylyn Commons features

The Mylyn Commons components were restructured and provisional packages were promoted to API. Several bundle IDs, package names and extension IDs were changed in the process. Classes in provisional packages were kept but marked as deprecated and will be removed in a future release. None of the changes break API backwards compatibility but integrations that consumed internal packages or extensions points may need to be adapted.

The following bundles were renamed: 

org.eclipse.mylyn.commons.identity      -> org.eclipse.mylyn.commons.identity.core
org.eclipse.mylyn.commons.notifications -> org.eclipse.mylyn.commons.notifications.ui
org.eclipse.mylyn.commons.repositories  -> org.eclipse.mylyn.commons.repositories.core
org.eclipse.mylyn.commons.team          -> org.eclipse.mylyn.commons.repositories.ui

A complete list of renamed and added bundles can be found on bug 305782 on comment 13.

The following packages were renamed: 

org.eclipse.mylyn.commons.identity     -> org.eclipse.mylyn.commons.identity.core
org.eclipse.mylyn.commons.repositories -> org.eclipse.mylyn.commons.repositories.core
org.eclipse.mylyn.commons.ui.team      -> org.eclipse.mylyn.commons.repositories.ui

The following provisional packages were promoted to API (see bug 360301): 

org.eclipse.mylyn.internal.provisional.commons.core        -> org.eclipse.mylyn.commons.core
org.eclipse.mylyn.internal.provisional.commons.ui          -> org.eclipse.mylyn.commons.ui
                                                           -> org.eclipse.mylyn.commons.workbench
                                                           -> org.eclipse.mylyn.commons.workbench.browser
                                                           -> org.eclipse.mylyn.commons.workbench.editors
                                                           -> org.eclipse.mylyn.commons.workbench.forms
                                                           -> org.eclipse.mylyn.commons.workbench.search
org.eclipse.mylyn.internal.provisional.commons.ui.actions  -> org.eclipse.mylyn.commons.ui
org.eclipse.mylyn.internal.provisional.commons.ui.commands -> org.eclipse.mylyn.commons.workbench.texteditor
org.eclipse.mylyn.internal.provisional.commons.ui.dialogs  -> org.eclipse.mylyn.commons.ui.dialogs
org.eclipse.mylyn.internal.provisional.commons.ui.editor   -> org.eclipse.mylyn.commons.workbench

In some cases provisional packages do not map directly to API packages but classes were distributed among several packages.

The following extension points have moved: 

org.eclipse.mylyn.commons.team.newWizards -> org.eclipse.mylyn.commons.repositories.ui.newWizards

The following extension IDs have changed: 

org.eclipse.mylyn.commons.team.navigator.Repositories -> org.eclipse.mylyn.commons.repositories.ui.navigator.Repositories
org.eclipse.mylyn.commons.team.category               -> org.eclipse.mylyn.commons.repositories.ui.category.Team

Porting from 3.0 to 3.6

Porting from 2.0 to 3.0
