• It's now possible to specify a custom version for the distribution UI in the WAR pom.xml using xwiki.extension.distribution.ui.version and xwiki.extension.distribution.wikiui.version.
• New Document.getLocale() API which should be used rather than the older Document.getLanguage() which is now deprecated.
• It's now possible to organize the slf4j log as a tree, see Logging Module.
