I just updated my blog to WordPress v5.0.3 which contains several bug fixes. As always, I backed up my files and database first. I have automatic updates disabled so I can do this beforehand. It included an update to the TwentyTwelve theme which I incorporated into my child theme. They were mainly just formatting and indention changes. As I always do, I updated the local copy on my PC before updating my blog here. The update seems to have gone fine. 🙂
