Here you can find a list with the latest changes in SMPlayer:
This is a maintenance release. This version provides a new fix for Youtube playback. We also improved the option to search for subtitles. There's a new feature, requested by many users: now it's possible to shut down the computer after playback.
Important The themes and skins use a new format. Now instead of installing hundreds of png files, the images are packaged in resource files. That means that you need to update the packages smplayer-themes and smplayer-skins as well.
