You may be right but there always will be bugs on more or less devices so it would be difficult for them to release version that have no bugs at all.

That makes sense but I saw many issues open on their GitLab related to this version so I’m bit afraid to switch.

To be honest I thought that alpha releases were unstable, not the “normal” ones. I wonder how unstable 1.13 really is if they released it.
