There have been several new and updated packages in Humble since its last sync a couple of weeks ago and it’s time to sync those new features and fixes to the main apt and dnf repositories.
Where did you see it marked as missing? If you’re looking on the buildfarm status page, sometimes I think it builds in an undefined state and occasionally presents the wrong data. A common example I see is a lot of regressions because of when the page was updated. The regressions are then fixed the next time the status page rebuilds.
