• RTL engaged below Home alt and using Terrain alt returning too high? (reported by Tridge and PeterB) -- RTL seems to be acting as expected. It was engaged at 121m above terrain and so that's the altitude it maintained until it returned home.
• AP_Mount's default mode being overwritten by RC input (discussion, PR) -- resolved for 4.5.2-beta1

• Use MicroXRCEDDSGen Binaries instead of making users compile it from source #26811
• Near Fly-away with 4.4.4 (EKF failsafe was disabled, discussion) -- no further communication, likely bad compass cal

• Copters turns North in Guided_NoGPS (issue, discussion, PR) -- fixed for beta5 (assuming there is a -beta5)
• ViewPro not holding level during hard maneuvers (PR) -- resolved in beta4 (although no confirmation from user) -- fixed for beta5 (assuming there is a -beta5)
• altitude jump when GPS/Non-GPS transitions switching altitude source of ExtNav to Baro (reported by Randy) -- should jump when moving from camera->baro, cannot reproduce otherwise.
• MP's MAVFtp can't download SYS files (MP issue) -- SITL only issue
• Logging removed on some boards? (issue, PR) -- needs backport?
• Sending unknown message (issue, PR) -- resolved for -beta3

• AutoTune crash -- ESC de-sync (discussion)
• Here4 does not support GPS-for-yaw (aka Moving baseline) (discussion)
