This is the first and hopefully final release candidate of the 4.1 release cycle (Roadmap). Being a release candidate, this release is sparse on new features, concentrating instead on stabilization of the features brought in Milestone 1 and Milestone 2.

New and Noteworthy (since XWiki Enterprise 4.1 Milestone 2)

Extension Manager improvements

The merge conflict resolution UI is now displaying all document changes as if you are comparing two versions from a document's history.

For developers

Diff module

A new diff/merge module has been added to make easier to deal with diff and merge both from component and scripts. See Diff module  for details.

Bug fixes and improvements

• The activity macro no longer allows sending messages. That functionality has been extracted into a reusable macro called messageSender. See and for more details.
• The Windows Installer should now work fine on Windows 7. The issue is that on Windows 7 the "Program Files" directory is now read only and since XWiki wanted to write in it it was causing startup issues. We've temporarily solved this in 4.1 by installing XWiki at the root of the C: drive for all Windows versions. This will be properly fixed in XWiki 4.2M1.

See the full list of JIRA issues fixed in this release.

API Breakages

The following APIs were modified since version 4.0:

• Breakage in Query module done to support adding several Filters to a Query:
  org.xwiki.query.QueryFilter: Method 'public java.util.List filterResults(java.util.List)' has been added to an interface
• This method should have been internal from the beginning:
  org.xwiki.environment.EnvironmentConfiguration: Class org.xwiki.environment.EnvironmentConfiguration removed
• The Job module is new and is still considered a "young API":
  org.xwiki.job.AbstractJob: Changed type of field status from org.xwiki.job.internal.DefaultJobStatus to org.xwiki.job.internal.AbstractJobStatus
  org.xwiki.job.AbstractJob: Return type of method 'protected org.xwiki.job.internal.DefaultJobStatus createNewStatus(org.xwiki.job.Request)' has been changed to org.xwiki.job.internal.AbstractJobStatus
  org.xwiki.job.AbstractJob: Method 'protected java.lang.String getId()' has been removed
  org.xwiki.job.AbstractRequest: Return type of method 'public java.lang.String getId()' has been changed to java.util.List
  org.xwiki.job.Job: Method 'public void join()' has been added to an interface
  org.xwiki.job.Job: Method 'public boolean join(long, java.util.concurrent.TimeUnit)' has been added to an interface
  org.xwiki.job.JobManager: Method 'public org.xwiki.job.event.status.JobStatus getJobStatus(java.util.List)' has been added to an interface
  org.xwiki.job.Request: Return type of method 'public java.lang.String getId()' has been changed to java.util.List
  org.xwiki.job.event.JobEvent: Return type of method 'public java.lang.String getJobId()' has been changed to java.util.List
  org.xwiki.job.event.JobFinishedEvent: Return type of method 'public java.lang.String getJobId()' has been changed to java.util.List
  org.xwiki.job.event.JobStartedEvent: Return type of method 'public java.lang.String getJobId()' has been changed to java.util.List
  org.xwiki.job.event.status.JobStatus: Method 'public java.util.Date getEndDate()' has been added to an interface
  org.xwiki.job.event.status.JobStatus: Method 'public java.util.Date getStartDate()' has been added to an interface
• The Extension module is relatively new and is still undergoing some API tuning:
  org.xwiki.extension.job.plan.ExtensionPlan: Return type of method 'public java.util.Collection getTree()' has been changed to org.xwiki.extension.job.plan.ExtensionPlanTree
  org.xwiki.extension.version.VersionConstraint: Method 'public boolean isCompatible(org.xwiki.extension.version.Version)' has been added to an interface
•  This class was added in 3.2M2 by error in a user-public package. It's been moved again in the internal package as it should have been. We don't expect many users to be affected by this:
  com.xpn.xwiki.doc.merge.MergeUtils: Class com.xpn.xwiki.doc.merge.MergeUtils removed
•  In 2.2M1 we refactored BaseCollection to add getXClass() but we forgot to add it to the ObjectInterface interface. Even though this could break user we think it's very limited since nobody should implement directly ObjectInterface; instead everyone should extend BaseClass or BaseCollection:
  com.xpn.xwiki.objects.ObjectInterface: Method 'public com.xpn.xwiki.objects.classes.BaseClass getXClass(com.xpn.xwiki.XWikiContext)' has been added to an interface
• The Autotag plugin has been extracted from the oldcore module and is now a module on its own so the following are not real breakages:
  com.xpn.xwiki.plugin.autotag.AutoTagPlugin: Class com.xpn.xwiki.plugin.autotag.AutoTagPlugin removed
  com.xpn.xwiki.plugin.autotag.AutoTagPluginAPI: Class com.xpn.xwiki.plugin.autotag.AutoTagPluginAPI removed
  com.xpn.xwiki.plugin.autotag.FrenchStemmer: Class com.xpn.xwiki.plugin.autotag.FrenchStemmer removed
  com.xpn.xwiki.plugin.autotag.Tag: Class com.xpn.xwiki.plugin.autotag.Tag removed
  com.xpn.xwiki.plugin.autotag.TagCloud: Class com.xpn.xwiki.plugin.autotag.TagCloud removed
• The WYSIWYG Diff and Sync plugins have been extracted into their own modules so the following are not real breakages:
  org.xwiki.gwt.wysiwyg.client.Images: Method 'public com.google.gwt.resources.client.ImageResource sync()' has been removed
  org.xwiki.gwt.wysiwyg.client.Strings: Method 'public java.lang.String sync()' has been removed
  org.xwiki.gwt.wysiwyg.client.diff.AddDelta: Class org.xwiki.gwt.wysiwyg.client.diff.AddDelta removed
