Working on better simulation implementation, fixed a bug where the port handle was not fully released

Added not yet working version of logging / log replay, fixed ALL bugs in main window, enabled full persistence in main window and serial link.

Improved line chart, brought back movement on HUD (but still looks somewhat wrong on the dials). Fixed logging for ground time mode

Fixed multi-thread message window bug, mainwindow should not hang any more on message windows from comm threads

Added new options for windows serial port, fixed a number of bugs, added customizing options to instrument widgets

Fixed initialization of Google Earth, works now flawlessly. Further improvements needed on simulation link and Google Earth JavaScript.

Substantially bugfixed and improved deactivation/activation and persistence of widgets. A lot of testing of Google Earth view, only minor improvements

Significantly bugfixed persistence and link adding/removal. Not yet fully there, but getting closer to release

QGroundControl now compiles under Visual Studio 9 / 2008. Google Earth support for Windows close to work.

First semi-usable version with new menu layout based on autopilot. Still very experimental. Current Bug: Linecharts do not work. Need to find out why

Still working on having independent builds for each MAV, most of the work is done, only Central Widgets remain to be instantiated and menu-controlled based on the autopilot

VERY EXPERIMENTAL. Saving of location for the common widgets now working and persisted across sessions. Needs to be extended to the individual autopilot widgets

Fixed imagery rendering issues. Robot position in Pixhawk3DWidget is now derived from the global pose (lat/lon/alt) instead of the local pose.
