The XWiki development team is proud to announce the availability of XWiki 6.4 Release Candidate 1. This release brings many improvements to the Mail Application and its API, including support for mail throttling. A new 'Wikis' category is available in the administration that groups together sections with wiki-related configuration options. Other smaller improvements (23) and a few bug fixes (15) complete this release. Would be great if you can give it a try and report whatever issues you may find so that we can fix them before the 6.4 final release.
