I managed to get a new package into #nix #nixpkgs: silx (an HDF5 viewer). The review process was a pleasure as usual, once it got started. Now I get a notification about a merge request for a new version of silx, apparently auto-generated by a bot. What's more, after testing this new version, I can just tell the bot via a comment to merge it into master.
This is the only way a huge package repository can be somewhat sustainably developed. Bravo! Do other distributions have something similar?
