Notice

This release among other changes continues evolvement of Clapper enhancer plugin system. With both new plugins added and some features ported from this core repo into being a plugin for the app. Some of these plugins have options that can be changed. Check application Tweaks tab in preferences window to browse and configure them.

Above includes movement of MPRIS, Server and Discoverer features into enhancer plugins. Applications that bundle Clapper as part of their container distribution are advised to build it with these features disabled in meson while adding newer implementations of these by bundling them as corresponding plugins. Flatpak apps can get these easily by including them as a runtime extension.

If both implementations are available on the host system, Clapper will automatically prefer and load enhancer based one.
