I may even add that it has been backported in a upgrade-4.4.0 branch with the tag 1.11.11.1. So it may resonnably be part of the coming 4.4 release.
@ric9k, a PR is a pull request in Github. A public mechanism where some code in development is reviewed before being included in the main code. About the release, if you have installed the 1.11.12 package, you will see a message during UI upgrade saying to revert the libcommhistory-qt5. You can do it, as explained by @vlagged. In my experience, you can also leave it like that, the upgrade automatically downgrading it to the official 1.11.11.1 (the downgrade will not raise any issue, as far as I know, since the changes between the two version don’t require data migration, conflicting files…).
