About this release

This is first v2.x release version which replaces all v1.9.x versions.

sudo ros os upgrade

And after reboot run also this command which upgrades console (any changes you have done to it WILL be lost so take backups first):

sudo ros console switch default

Great work on this @olljanat! Thanks so much for keeping the project going. My upgrade went very smoothly - I haven't observed anything strange so far.

Not sure if this is intended or not, but my user docker was not updated as part of the upgrade. Updating user docker to 25.03 per the user guide seems to have worked great so far.

Docker should update automatically to 24.0.9 on OS upgrade but it might be that if you had changed version with ros engine switch earlier then it comes as default because version is stored to cloud-init.
