The XWiki development team is proud to announce the availability of XWiki Enterprise 5.1 Release Candidate 1. This is mostly a stabilization release leading to XWiki 5.1 and it brings Sorl search improvements and bug fixes as we plan to make Solr the default search engine in 5.1 final. There is also a new Menu Application in platform (not bundled by default) to help you create navigation menus.
See the release notes for more information.
