A total of 12 issues have been patched since Kodi 17 RC3, but your help is now needed more than ever to test drive this fourth Release Candidate and report any bugs you might encounter. New improvements include the ability to change song ratings, smaller timeouts for some audio streams, miscellaneous updates to the Estouchy and Estuary skins, better support for devices running Android 7 “Nougat,” and better refreshing of favorites. Other enhancements added in Kodi 17 RC4 include removal of the changes implemented in a previous development release because they disabled the plugin listing cache causing slower browsing speeds, multiple improvements and some new features to the default Chorus2 web interface, as well as the ability to stop playback before uninstalling PVR (Personal Video Recorder) add-ons.
