Upgrades should be working on OSX Mavericks, Linux, and sort of on Android. This needs more testing, so I have temporarily made the daily builds think they are an older version than the last git-annex release. So when you install a daily build, and start the webapp, it should try to upgrade (really downgrade) to the last release. Tests appreciated.
Looking over the whole upgrade code base, it took 700 lines of code to build the whole thing, of which 75 are platform specific (and mostly come down to just 3 or 4 shell commands). Not bad..
Last night, added support for quvi 0.9, which has a completely changed command line interface from the 0.4 version.
Plan to spend tomorrow catching up on bug reports etc and then low activity for rest of the week.
