This is not a minor point release though.
The migration to libglvnd, subsequent changes to mhwd and all drivers, and the simultaneous replacement of all glx symlinks is what is causing all the issues. This caused many issues in Arch also and is not a straight forward upgrade given the vast array of hardware configurations.
Having been a small part of the testing of this in unstable and testing I honestly don’t know what more could have been done, bar more testers being involved with a broader selection of hardware and driver configs.
The real issue is that whilst the Manjaro dev team endeavour to make Manjaro user friendly and non technical as possible, under the hood is still an Arch rolling system that most likely will require manual intervention for complicated upgrades at some stage during its life.
Blindly assuming the small selection of Manjaro automated tools will be able to mask and obfuscate all the underlying complexity in all situations is noble, but ultimately wishful thinking. The Manjaro dev team is pretty small and stretched pretty thin, and whilst progress is always being made, there is no magical pill.
I do agree with you though that the notification system could be improved. Where it is recommeneded that some updates be performed at the command prompt with pacman, there should be provisions for this.
Octopi already has a news tab which contains a link to all update announcement threads on the forum, users need to know to use this. Not sure if Pamac has the same feature, don’t use it.
