Plugins and Bug Fixes

Version 0.7.1 has been released! Version 0.7.0 never worked like it was supposed to because there where unfortunately too many bugs. Therefor we have spent much time to test this release so that not the same would happen again. A new thing in this release is the concept of plug-ins. Everything that isn’t directly connected to the playing media has been moved to plug-ins, that include the Movie Trailers, Video Library and Music Search. These plug-ins are no longer included but can easily be downloaded and installed from inside the player. Also there are 3 new plug-ins that are available for download. Read more →
