This is the release notes for XWiki Platform, XWiki Enterprise and XWiki Enterprise Manager. They share the same release notes as they are released together and have the same version.

This is the first and hopefully final release candidate of the 4.2 release cycle (Roadmap). Being a release candidate, this release contains bugfixes and polishing, most of them focused on the new distribution wizard.

If you're upgrading from an older version and you use the new Distribution Wizard to upgrade your wiki pages you'll notice that it'll ask you to merge all pages that have been modified between your version and XWiki 4.2. This is because currently the Distribution Wizard doesn't know which version you have and thus asks you to perform the merge manually. This operation may take a long time (up to 20 minutes or so). Thus at the moment if you're upgrading from a previous version we recommend that you Cancel the Distribution Wizard and instead Import the new XAR. This problem is reported in this issue and should be fixed in the next release.

New and Noteworthy (since XWiki 4.2 Milestone 3)

Improved Distribution Wizard

The look&feel of the Distribution Wizard has been greatly improved. We added an overview step to explain the goal of the wizard and list its steps.

The wizard is not yet production ready. It has a couple of issues we hope to fix very soon:

  • information about core extensions is collected lazily and thus if you check distribution details just after starting XWiki you get incomplete information
  • installing or checking the details of the user interface extension takes a couple of minutes depending on your internet bandwidth and the load of the remote extension repository
  • some merge conflicts are reported even when the database is empty

Invalid extensions are now marked differently in the last step.

Backward Compatibility and Migration Notes

General Notes

You may also want to import the default wiki XAR in order to benefit from all the improvements listed above.

Always make sure you compare your xwiki.cfg and xwiki.properties files with the newest version since some configuration parameters were added. Note that you should add xwiki.store.migration=1 so that XWiki will attempt to automatically migrate your current database to the new schema. Make sure you backup your Database before doing anything.

API Breakages

The following APIs were modified since XWiki 4.1.4:

  • The logging module is new and is still considered a "young API". Added new methods to manipulate loggers levels.
    org.xwiki.logging.LoggerManager: Method 'public org.xwiki.logging.LogLevel getLoggerLevel(java.lang.String)' has been added to an interface
    org.xwiki.logging.LoggerManager: Method 'public java.util.Collection getLoggers()' has been added to an interface
    org.xwiki.logging.LoggerManager: Method 'public void setLoggerLevel(java.lang.String, org.xwiki.logging.LogLevel)' has been added to an interface
  • The Job module is new and is still considered a "young API". Added two new methods to check and remove custom properties.
    org.xwiki.job.Request: Method 'public boolean containsProperty(java.lang.String)' has been added to an interface
    org.xwiki.job.Request: Method 'public java.lang.Object removeProperty(java.lang.String)' has been added to an interface
  • New InstalledExtension#isValid() method.
    org.xwiki.extension.InstalledExtension: Method 'public boolean isValid(java.lang.String)' has been added to an interface
  • The Extension module is relatively new and is still undergoing some API tuning. New method to access environment extension. Also added new methods to execute custom checking before installing/uninstalling an extension and new methods to access local:installed extensions.
    org.xwiki.extension.repository.CoreExtensionRepository: Method 'public org.xwiki.extension.CoreExtension getEnvironmentExtension()' has been added to an interface
    org.xwiki.extension.handler.ExtensionHandler: Method 'public void checkInstall(org.xwiki.extension.Extension, java.lang.String, org.xwiki.job.Request)' has been added to an interface
    org.xwiki.extension.handler.ExtensionHandler: Method 'public void checkUninstall(org.xwiki.extension.InstalledExtension, java.lang.String, org.xwiki.job.Request)' has been added to an interface
    org.xwiki.extension.repository.InstalledExtensionRepository: Method 'public org.xwiki.extension.InstalledExtension getInstalledExtension(org.xwiki.extension.ExtensionId)' has been added to an interface
    org.xwiki.extension.repository.LocalExtensionRepository: Method 'public org.xwiki.extension.LocalExtension getLocalExtension(org.xwiki.extension.ExtensionId)' has been added to an interface
  • Fix method name typo (adding new method). This interface is not really supposed to be implemented except by internal class.
    org.xwiki.properties.PropertyDescriptor: Method 'public java.lang.reflect.Field getField()' has been added to an interface
  • The method getPreviousBlockByType() was moved to Legacy. There's no API breakage for the user.
    org.xwiki.rendering.block.CompatibilityBlock: Method 'public java.util.List getChildrenByType(java.lang.Class, boolean)' has been added to an interface
  • Added method to get the author of the macro.
    org.xwiki.rendering.macro.wikibridge.WikiMacro: Method 'public org.xwiki.model.reference.DocumentReference getAuthorReference()' has been added to an interface
  • Add a method to the oldcore/wikimacro bridge.
    org.xwiki.rendering.macro.wikibridge.WikiMacroFactory: Method 'public boolean isAllowed(org.xwiki.model.reference.DocumentReference, org.xwiki.rendering.macro.wikibridge.WikiMacroVisibility)' has been added to an interface
  • These classes below have never been used. It was supposed to be the start of the removal of Struts but since it hasn't progressed so far we're removing stray code from master. Experiments should be done on feature branches.
    org.xwiki.container.servlet.XWikiServlet: Class org.xwiki.container.servlet.XWikiServlet removed
  • Removed protected method (registerWikiMacros) that was not supposed to be used from outside (was protected for unit tests hacks).
    com.xpn.xwiki.XWiki: Method 'protected void registerWikiMacros()' has been removed
  • Chart plugin has been moved from oldcore to its own module. There's no API breakage for the user.

  • TODOAndreas, please explain why we have to break backward compatibility for the Chart module.
    org.xwiki.chart.model.ChartModel: Method 'public org.jfree.chart.axis.Axis getAxis(int)' has been added to an interface
    org.xwiki.chart.model.ChartModel: Method 'public java.lang.Number getCellValue(int, int)' has been removed
    org.xwiki.chart.model.ChartModel: Method 'public int getColumnCount()' has been removed
    org.xwiki.chart.model.ChartModel: Method 'public java.lang.String getColumnHeader(int)' has been removed
    org.xwiki.chart.model.ChartModel: Method 'public org.jfree.data.general.Dataset getDataset()' has been added to an interface
    org.xwiki.chart.model.ChartModel: Method 'public int getRowCount()' has been removed
    org.xwiki.chart.model.ChartModel: Method 'public java.lang.String getRowHeader(int)' has been removed
    org.xwiki.chart.model.DefaultChartModel: Class org.xwiki.chart.model.DefaultChartModel removed
    org.xwiki.rendering.macro.chart.ChartDataSource: Field PARAMS has been removed, but it was previously a constant
    org.xwiki.rendering.macro.chart.ChartDataSource: Field SOURCE has been removed, but it was previously a constant
  • The getParametersMap() should never have been a public API. I was probably added there just as a way to reduce the Class Fan Out, which is the wrong solution.
    org.xwiki.rendering.macro.chart.ChartMacroParameters: Method 'public java.util.Map getParametersMap()' has been removed
  • Added a new sendMessageFromTemplate() method signature that uses a map of parameters instead of a VelocityContext
    com.xpn.xwiki.plugin.mailsender.MailSender: Method 'public int sendMessageFromTemplate(java.lang.String, java.lang.String, java.lang.String, java.lang.String, java.lang.String, java.lang.String, java.util.Map)' has been added to an interface
