Using the repology.org's API, I've generated a list of possible updates that can be made to the nix packages. It lists the current nixpkgs_unstable version on the left of the arrow and the version that exists in some other package manager on the right of the arrow. It is based on what is on the nixpkgs_unstable channel, so some of these might have already been updated. If you work on packages from this list, feel free to post a comment and I'll check it off the list.
Also, I'm curious if people think this is useful. Feedback is very welcome!
Possible package updates
I maintain Tribler, I've been testing 7.0.1 in NixOS and it crashes constantly due to this bug, making it unusable, so I'm waiting to update it.
It's useful but please exclude the Python packages as we often cannot update to the latest version.
Alt Sisyphus calls Monotone 1.2 something that is not even a pre-release, and the upstream advertises 1.1 as the latest version.
ttf2pt1 is probably an interesting case of a false positive: 3.4.4 vs 344
Yeah, there are definitely false positives in here! Repology.org has a mechanism for dealing with them, and they accept PRs.
No idea what would be a good way to handle this in general, to be honest. After all, Firefox did have both 35 and 3.5 as major releases.
Maybe package maintainers could be listed too. This way it would be easier to look at all packages someone maintains without having to look at the full update list.
xfce*xfceUnstable (AKA 4.13) #327634.12 is frozen, upstream does not even fix bugs4.12 and 4.13 is GTK2 vs GTK3, so the changes is not minor as it might look from so little version difference of individual components.perl* - there are already 2 tools upgrading nixpkgs from CPAN and the patch is known (https://github.com/NixOS/nixpkgs/pull/36147) and the only problem is to apply it without damage to the other packages@volth Perl has been blacklisted. Added blacklist for xfce now.
