The usage of categories in news posts is weird. The Koha newsletter seems to be using every category available, while 3.22 is not tagged at all. https://koha-community.org/category/release/ has mostly 3.20. Where is 3.22? Why are all the community newsletters showing up there? https://koha-community.org/category/release/3-22/ has newsletters almost exclusively. 3.22.1 is the last one listed.
I've had a chat with the people who do these, I hope they are putting a little more thought into how they categorise things. Liz
