### D.1 : Holybro Carrier board Ethernet connection testing

[https://github.com/PX4/PX4-Autopilot/issues/20280](https://github.com/PX4/PX4-Autopilot/issues/20280)

- Ethernet sometimes acts weird when using Holybro Carrier board - Alex
- 2 boards are never working & one board used to work but now doesn’t work
- Through the oscilloscope, the 50V~ on the signal line is observed, maybe capacitor issue?

TODO: @david_s5 any comment on this?

### D.2 : DroneCAN RPM feedback messaging

- Maxon motors is using UAVCAN ESC and is wondering about it

### D.3 : Changing speed in the Mission

TODO: Will start new issue to discuss how to handle `DO_SET_SPEED` command.

> <https://github.com/PX4/PX4-Autopilot/pull/20360>
>
> This PR adds the ability to set a max XY velocity constraint from a flight task.… For instance, in a flight task where you want to set a position setpoint but not a velocity, you can set a max velocity constraint and let the position controller adjust the velocity automatically but not exceed the constraint.

## ❗ High priority queue

* * *

Discussion based on: [https://github.com/orgs/PX4/projects/24](https://github.com/orgs/PX4/projects/24)

## 🌾 Release

* * *

- Having ‘pre-release’ candidates (like Ubuntu), instead of having the `main` branch mostly would give people more confidence to try out the branch for flight testing - @mcsauder
- Alpha/Beta/RC1, 2, 3, …
- Having clear intermediate releases, it puts 🔥 under people and gives a sense of timespan & can help people devote more resources into testing.

### How do we track the testing (bench & flight) of the releases? - Daniel

- We need a tool / (discuss forum) to report testings on a specific releases
