[bresch]

I'm not exactly sure what should go under "Highlights". Shouldn't be the "overall best improvements and new features" ? Enable RC-Override in Take-off (PR #14022) and Pre-flight check: Disable mag field strengh check via parameter (COM_ARM_MAG_STR) are minor modifications that could go under Failsafe / Commander / Navigation improvements and shouldn't be here.

Is "Computer Vision & Autonomy" redundant to "PX4/Avoidance"?

[mrpollo]

Thanks for the edits @bresch, please let me know if the changes work for you.

@jinger26 Yes. A remnant of the last release notes, not sure I remember what was going on there right now. Take a look -> PX4 v1.10.0. It's gone now, thank you.

Is dual battery support in v1.11? https://github.com/PX4/Firmware/pull/12551 and https://github.com/PX4/Firmware/pull/12034

They're not in the list (yet)

@mrpollo FMI is this ever going to release?

[jinger26]

Add to supported hardware: Holybro PIX32V5 HEX Yellow/Orange? CUAV X7, X7Pro, Nora?

verify with @dagar
