Agreed, I still am a bit confused about the versioning showed on that screen prior to deCONZ 2.23.01. I opened an issue (mistakenly) here: Wrong version date shown in Phoscon · Issue #7239 · dresden-elektronik/deconz-rest-plugin · GitHub
In my case:
“Version 2.22.02 / 9/19/2022”
seemed to point to a Phoscon app version from that date, but I couldnt find a match in changelog.en
