After months of testing, ArduCopter 3.2 (aka APM:Copter) is ready for widespread use and we invite all users to give it a try. In order to manage the support load at first it will be available only through the Mission Planner and APM Planner2's Beta Firmwares link. This link is visible from the regular "Install Firmware" page if you check the "Advanced View" on the Config/Tuning >> Planner page. On APM Planner2 the "Advanced View" it is under the File menu.
In about two weeks we plan to replace AC3.1.5 with AC3.2 as the default version dispensed by the ground stations.
The full list of changes can be found in the ReleaseNotes but here are the highlights:

If you hit issues, please post them in the APM Forum and include a dataflash log file if possible.
