The poor blog has been neglected, but it keeps coming back from the dead anyway.
Though, in the meantime, 4.1 and 4.2 got taken care of and released into the wild. You can find 4.2 on your friendly neighborhood App Store. These are both incremental releases, but there is some good stuff in there like Dropbox support (finally) and multicopter model types.
The coding elves are busy working on putting in a few cool things for whatever comes after 4.2. Parallel charging/discharging support is wrapping up along with a few other goodies.
