Moderator’s request: Dear community members, please respect the specific posting policy of this thread. This is to track and consolidate issues that are
a) OH4 specific (no OS or 3rd party software issues). openHABian is OS, the thread for that is here.
b) analysed to a reasonable extent and applicable or of interest to reasonably many users
c) identified to be related to changes in OH4 versus latest OH3 (3.4.5).
Means this thread is not to support you with your personal upgrade process so please help with this thread serve its purpose.
If you want help with upgrading your very own system, please open a separate thread for your request and mind the general posting rules. You are welcome to report any relevant findings back here.
Anyone about to upgrade, make sure you check the upgrade process section of the Release Notes BEFORE you upgrade.
Also check out the FAQ on OH4 upgrade issues @laursen has compiled for your convenience.
