Q: This release contains #2305 - I thought we were reserving this for 0.5.0?

I had the same thought, but it turns out that @janmasrovira merged it 4 hours ago. So, it seems logical to me to label all the merged commits after 0.4.2 as part of tag 0.4.3, including this one.

For now, let's leave it as it is. Next time, we double-check before merging on the day of release to avoid this kind of issue.

Well, it is not set in stone, we can always easily use git so that #2305 is not part of 0.4.3
