This is the first and hopefully final release candidate of the 4.1 release cycle. 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. The 4.1 cycle brings new 3D graphs made with pure XWiki syntax, safer Groovy scripting, and new localization through timezone settings.
