I just connected my N900 to my PC and checked for updates via Nokia software updater and was surprised to find a new firmware update for the device. The update is version 1.2009.44.1 and has been tested select members of the maemo community for a few weeks nowWhile the download and update is still going on will post the changelog once the update is done.
While I would love a major update. Users in the Maemo talk are describing this a minor update.
