Fix HDMI output on pi zero
Increase CPU speed on all pi models
Allow QOpenHD to switch 2nd camera from PiP to fullscreen with RC camera switching
- There's no extra setting for this, as long as camera switching is set up and working and the RC levels match your TX
- Double check the RC levels in the settings file (Camera2ValueMin etc) if you can't get one of the RC levels to trigger switching
- The temporary ENABLE_QOPENHD_PIP setting is removed and no longer necessary
Update the default RC camera levels
- These are the Camera2ValueMin, Camera2ValueMax values
- They control what happens when your camera switching channel hits a specific RC value
- Ordinarily, a 3 position switch will use 1000, 1500, and 2000 RC levels
- If you need to update your old settings file, see here
- Level 2 does PiP, level 3 switches the 2nd camera to full screen on HDMI (not on Android yet)
Add documentation for VEYE camera settings
Update VEYE imx290/imx307 camera driver
Add new VEYE camera settings
- Saturation, brightness, sharpness, WDR AE, etc
- If you need to add the new settings to your old settings file, see here
Update Seek thermal driver
- Package now includes the FFC calibration command (for advanced users, will be handled automatically in 2.1)
Internal changes
- Replace dump1090-fa with dump1090-mutability

The font dropdowns in QOpenHD may not update in both locations when you change the font
In some cases QOpenHD might freeze on the ground station, this isn't a bug in the app itself but appears to be an issue with the Raspbian Buster 4.19.x kernel. We're testing an updated kernel to fix it.
Air-side power stats (voltage/current from external sensors) may not be arriving in QOpenHD at the moment
The boot screen may flicker for a moment when a TX is connected to the ground, this is expected at the moment (there is a bug in a system library we use)
The first few messages may not show up on the boot screen at the moment
The size of OSD elements in QOpenHD is fairly small on high resolution screens, HiDPI is not currently being detected automatically. If necessary you can increase the scale in the QOpenHD settings panel under App->Screen, you can also edit /boot/qopenhd.conf and reboot
Video may stutter or freeze when ground recording to SD card is enabled with VIDEO_TMP=sdcard
- This is an old problem, the settings file has had a note about it for probably a year or more
- A temporary solution is to use VIDEO_TMP=memory instead
- Will be resolved soon by separating the recording system from the rest of the video pipeline so it can't affect live flight
Some parts of the old OSD may be reversed when Vector Open Telemetry is in use (#283)
