Just updated my blog to WordPress v6.8.2 which is a maintenance release that fixes 20 Core tickets and 15 Block Editor issues. As always, I backed up my files and database first. I have automatic updates disabled so I can do this beforehand. As I usually do, I updated the local copy on my PC before updating the blog here.
My TwentyTwelve parent theme was updated to version 4.6 ( changelog ). Comparing files with the previous version, I found out that none of the changes affected my child theme. So far the update seems to have gone well. 🙂
