Important Bugfix

This update fixes a bug where Rocket cannot pick the current wallpaper from /.config/plasma-org.kde.plasma.desktop-appletsrc, and thus could not keep up sometimes with wallpaper changes.
Note that Plasma wallpaper packages are not supported, only image files (such as .jpeg, .png, .svg etc.) are.
If you are an old user, it suffices to grab the executable and replace the old one in ~/.local/bin/ (or wherever you have Rocket installed).
