New MongoDB version on my computer
This morning I got updates on my AlmaLinux 9.8.
I get the updates with an Update-Script where it checks everything on the computer.

And there are the Updates of MongoDB.
MongoDB Updates
You see updates of gemu, too
You see, that MongoDB comes from an own repository.
