Not sure if I also need to add the entry to the CHANGELOG? This is done on devel under the 2023.5.0 section. Perhaps you look at fixes from that section when creating a patch release and add them to the respective 2023.4.X section.

Could you create a 2023.4.2 section in the changelog and add it to there? I then compare the devel changelog to the one in main when I do the next major release, and will remove anything that is duplicated from the previous patch release.

[lohedges]

Yes, no problem. I just wasn't completely sure of the system since you could end up adding a section for a patch release that never happens. I guess it all gets sorted out at release time anyway, so it's good to have something to cross reference.

Done 👍
