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

This milestone brings a couple of improvements to Extension Manager, Panels Application and the Space Deletion UI, together with a couple of developer oriented features such as a JSON service for Solr and a better and cleaner (HTML5-friendly) way of storing and obtaining in JavaScript information about the current document. Also, 31 bugs were fixed in this release, so this makes it yet another reason to upgrade and try it out.

New and Noteworthy (since XWiki 6.3-milestone-1)

Full list of issues fixed and Dashboard for 6.3.

Extension Manager improvements

The extension source URL and issue manager URL are now displayed in the extension description when available.

Panels Application

It is now possible to select which applications are displayed in the App Bar, and which are not:

Miscellaneous

• The standalone distribution now uses Jetty 9.2.3.v20140905 (was using version 8.1.15.v20140411 in XWiki 6.3-milestone-1). This should be transparent for the user since XWiki provides its own start/stop scripts around Jetty.
• The Delete Space feature now lists the documents inside the space you are going to delete. This should help people differentiate between the UI of Delete Page and the UI of Delete Space so that fewer mistakes occur when not paying much attention(
  
  )))

For Developers

Solr JSON Service

You can now make search requests from JavaScript using the Solr JSON service. The results include all the information that is indexed by Solr so you can display them as you wish. See the Solr Search Application documentation for more details.

Document Meta Informations

• We have introduced a new JavaScript API to get informations about the current document. See: JavaScriptAPI.

Miscellaneous

• New outputOnlyHtml option for the livetable macro to output only the HTML, without the syntax specific wrappers. See the documentation.

Backward Compatibility and Migration Notes

General Notes

When upgrading make sure you compare your xwiki.cfg, xwiki.properties and web.xml files with the newest version since some configuration parameters may have been modified or 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 6.2.2:

• Add scm informations to extensions descriptors. Should be safe enough since most repository handlers extend AbstractExtension instead of directly implement Extension
  org.xwiki.extension.Extension: Method 'public org.xwiki.extension.ExtensionIssueManagement getIssueManagement()' has been added to an interface

• Add issue management informations to extensions descriptors. Should be safe enough since most repository handlers extend AbstractExtension instead of directly implement Extension
  org.xwiki.extension.Extension: Method 'public org.xwiki.extension.ExtensionScm getScm()' has been added to an interface

• Never really been supposed to be exposed as an API.
  com.xpn.xwiki.objects.BaseElement: Accessibility of field localEntityReferenceSerializer has been weakened from protected to private
  com.xpn.xwiki.doc.XWikiDocument: Method 'public java.lang.String ajc$privMethod$com_xpn_xwiki_doc_XWikiDocumentCompatibilityAspect$com_xpn_xwiki_doc_XWikiDocument$serializeReference(org.xwiki.model.reference.DocumentReference, org.xwiki.model.reference.EntityReferenceSerializer, org.xwiki.model.reference.DocumentReference)' has been removed

• Changed the LESSCache interface and the LESS Script Service because the cache was poorly designed (see: XWIKI-10776).
  org.xwiki.lesscss.LessCompilerScriptService: Method 'public boolean clearCache(java.lang.String)' has been removed
  org.xwiki.lesscss.LESSCache: Method 'public void clear(java.lang.String)' has been removed
  org.xwiki.lesscss.LESSCache: Method 'public void clearFromColorTheme(java.lang.String)' has been added to an interface
  org.xwiki.lesscss.LESSCache: Method 'public void clearFromFileSystemSkin(java.lang.String)' has been added to an interface
  org.xwiki.lesscss.LESSCache: In method 'public java.lang.Object get(java.lang.String, java.lang.String, java.lang.String, java.lang.String)' the number of arguments has changed
  org.xwiki.lesscss.LESSCache: In method 'public void set(java.lang.String, java.lang.String, java.lang.String, java.lang.String, java.lang.Object)' the number of arguments has changed
