It takes time before a release becomes generally available. The code for 2024.2.3 was published about 2 hours ago.
It then has to go through a process that creates docker containers. Home Assistant checks an index of available releases and that index is updated only when the containers are available (or thereabouts).
If you’re one of the minority who runs the pure-python version of Home Assistant then you can upgrade as soon as its code is published. For the vast majority who run the docker version (Home Assistant OS, Home Assistant Supervised, or Home Assistant Container) you have to wait until they become available.
EDIT
I may be wrong but I believe this may be the index it references.
At this point in time, it indicates 2024.2.2.
Here’s a link showing the current status of the build process.
thnx for the extended response.
normally I don’t update directly after a release but I try to keep restarts to a minimum and I need to restart for another reason and noticed the new release on github. so I thought I could combine, and I still can, I only need to wait a little bit longer.
