I´ve changed the upgrade channel to: snap switch rocketchat-server --channel=7.x/stable
But as you can see the server / rocket chat cannot find any upgrade to the latest version which apparently seems to be version 7.2.1.
They just haven’t released a newer version as yet. 7.0 is supported for 6 months.
Snaps are the most used deployment. They do not upgrade them without a lot of thought and testing to save everyone complaining that stuff has broken. If there is a delay it is to fix an issue.
If you want cutting edge then use a different type of deployment. Snaps will get released as and when they feel ready to do so and nothing is going to change that.
You can of course use docker, or just takes the source code and build it yourself.
So you do have a choice. Sit and wait patiently, or use another deployment method.
Thanks for the answer and explanation. It is appreciated!
I just saw the notification over and over that a new version has been released and I could not directly figure out why it was not available on the Snaps version. But you have explained it neatly, so now I know why!
