Issue details
Mission Planner incorrectly reports that there is a new firmware version available when there is not. See the attached screenshot - Mission Planner reports that APM:Copter V3.5.0 is available but the latest stable version number shown in http://firmware.eu.ardupilot.org/Copter/stable/PX4-quad/git-version.txt is V3.4.6, which is the version I have installed already on my Pixhawk (this can also be seen in the screenshot).
