FYI, I currently have no plans to provide future monthly maemo.org feature jars as the Maemo 5 User Interface is considered stable by Nokia (and as the amount of votes was also quite static for the last months, no bigger chances).
MeeGo Handset is where the unstable development is taking place. If you are a developer (not a "normal" end-user) feedback about MeeGo Handset User Interface issues is specially welcome, e.g. via the MeeGo bugtracker at https://bugs.meego.com.
