is there a rss feed or some sort of "tracking" website to get the latest package version?

I wrote a script: https://github.com/voncloft/Voncloft...heckrepository

That will compare my linux from scratch repository on my pc against distrowatch's package manager - once the updates have been found, Iget a notification and I apply the update to github.... however there are still packages missing for example firefox just released a new version, however apparently nss is out of date and is not tracked on distrowatch. I am currently upgrading nss......had to manually update the script on my repo on github, would have been nice for my script to do it for me lol.....call it laziness but I like my script.

Is there another way to get "notified" of package updates?

Thanks.
