The XWiki development team is proud to announce the availability of XWiki Enterprise 3.4. XWiki Enterprise 3.4 is a stabilization release as we are approaching the end of the 3.x cycle so its main goal was to improve the Extension Manager and App Within Minutes features. However, this release also comes with a new look and a new default wiki page syntax. Other things to check are the new delete space menu, the space templates, the minimized action menu, the new display macro and the fact that non-ASCII characters are preserverd in attachment file names.
