Hi!
It's a bit late, but I just want to announce that we have released version 0.20 of the Geany Plugins, which requires Geany 0.20. Tarballs and their corresponding GPG signatures can be found at http://plugins.geany.org/downloads.html
A comprehensive list of changes can be found at http://plugins.geany.org/geany-plugins/geany-plugins-0.20.NEWS
