RFC post here. After more than one year of service, the MAVLink 1.0 spec needs an update to 1.1 to adjust for developments made on autopilot platforms (new messages) and to clarify and improve some aspects of the protocol. In contrast to the upgrade from 0.9 to 1.0 the intent is to make this a 100% compatible update, so that autopilots and ground control stations can benefit from the new functionality, but won't be left behind when not immediately upgrading.
This post is mostly directed at interested users and implementers and make the general public aware that protocol change proposals should be handed in now.
