Enonic has just released Enonic XP 6.5.2, due to a couple of bugs that have caused problems for developers. For installations already running version 6.5.1, an upgrade to 6.5.2 is virtually without any risk, and highly recommended, especially in environments under development.
The bugs are listed in the release list on Github: https://github.com/enonic/xp/releases/tag/v6.5.2
The release can be downloaded from our repository: http://repo.enonic.com/public/com/enonic/xp/distro/6.5.2/ - and the latest release is always available on our web-pages: https://enonic.com/downloads
