This is what I did.  After upgrading from Ubuntu 18 to Ubuntu 20, I 
added the dovecot APT repo and installed from there.  It all went 
smoothly, and the migration notes were sufficient.

At some point I will upgrade that system to Ubuntu 22, but I will be 
waiting until all the PHP webapps I am using are upgraded to support PHP 
8.1.  If you use a lot of PHP apps, the upgrade from PHP 7.4 in Ubuntu 
20 to PHP 8.1 in Ubuntu 22 is probably going to break at least one of 
them.  App developers are not adjusting to PHP 8.x very quickly.

For the gurus:  Is there an expected ballpark release date for 2.4 
and/or 3.0?

Thanks,
