The OpenELEC team is proud to announce its 1st Beta of OpenELEC 6.0.
Internally this will be known by the less-catchy name OpenELEC 5.95.1.
The OpenELEC 5.95 release series are test releases (beta) for OpenELEC-6.0.
OpenELEC-6.0 will be the next stable release, which is a feature release and the successor of OpenELEC-5.0.
The most visible change is the update from Kodi-14.2 Helix to Kodi-15.0 Isengard (beta 1). Beginning with Kodi-15 most audioencoder, audiodecoder, PVR and visualisation addons are not more included in our base OS, but they are avaible via Kodi's addon manager and must be installed from there if needed. Our own PVR backends like VDR and TVHeadend will install needed dependencies automatically. Other then that please refer to http://kodi.tv/kodi-15-0-isengard-beta-1/
to see all the changes in Kodi-15.
