The only thing I've seen mentioned specifically is an issue with pydantic versions. Even after the 1.9.3 update to fix that for bullseye I think bookworm needed a slightly older version than that.
I installed Octoprint with Octoprint_deploy this weekend on a fresh install of bookworm.
Had zero issues with the install, and no issues with operation so far. This was on a Pi4. Pi5 shouldn't have any issues. Octoprint runs in Python, so the underlying interpreter still sees all the GPIO as it should, Etc..
Priority were delivered yesterday, so first to order will be soon.
So PiHUT UK for anyone using magpi/HackSpace codes have them now.
Pi5 documentation should be on Monday, at least that's what I was told on Friday.
Hopefully someone makes a plugin to read the voltages (and some current), which will be good to check for a good 5V input.
Dual camera for monitoring should be easier now OctoPi has put the effort in to move over. At least if you don't use a display though USB are on separate lanes now.
I didn't get the time to try the first deploy method, but will give OctoPi nightlies a go first as that's what people tend to use (I think?) on a Pi.
Also Pi Imager (v1.8) has been updated, so you might want to check the alterations for saying what works on what Pi. So Pi1/2 series don't get offered 64bit and probably recommend 64bit for Pi4&5.
