Home Assistant OS vs Home Assistant version

I’ve just installed Home Assistant OS on my Raspberry Pi and it says the version is 2022.x.y But I see on home-assistant.io that the latest version is 2023.2.3. When I check for updates in the web UI it says there are none available. Is that correct or is there another update process on the Pi itself?

If it’s correct is there another way to install home assistant on a Raspberry Pi so that it can get the latest version?

It usually installs the latest version as part of the boot process (that’s why you get the message about it taking up to twenty minutes), so I’m not sure what is going on. I would suggest rebooting the Pi and seeing if that helps, and make sure it has a good connection to your network.
