22.04 install questions

[Stuart McGraw]

I switched from Fedora to Ubuntu a few years ago and have been running 18.04.  But with the release of 22.04, this will be the first time I will upgrade between major versions.  (I will be doing a fresh install rather than an upgrade to clean up some of the learning mistakes I made in 18.04.)  There are still things about the Ubuntu release model I don't understand.

I use a backup program called "Bacula".  However, it does not seem to be available for 22.04 (https://packages.ubuntu.com/search?keywords=bacula).  Does this mean it's been dropped or rather that it will be released for 22.04 later?  If the latter, how to get an idea of when?  How can find the answers myself without asking in a place like here?

I understand 20.04.1 will be released in August.  If I install 20.04 now and do the usual upgrades though August, will I have the same system in August as I would get by installing 20.04.1 then?

Thanks for any enlightenment!
