Touché.
The issue with Plasma 6.3. is rather a sign that Plasma releasing independently from distro release schedules is not an optimal scenario! Again we come back to the discussion surrounding releasing 3x a year vs 2x a year and align with release targets of the major distros, specifically Fedora and Ubuntu like GNOME does. The underlying distro matters as much as the Plasma release, so KDE OS makes sense!
Take the example of Fedora, Plasma 6.1 Beta aligned perfectly with Fedora 40 Beta, while Plasma 6.2. Beta aligned perfectly with Fedora 41 Beta. This time Plasma 6.3. released ahead of the beta testing stage of Fedora 42, so a lot less users were compelled to beta test Plasma 6.3. because they were happily using the latest stable Fedora 41 as there’s no beta for Fedora 42 yet, and like me couldn’t be bothered to install KDE Neon or whatever just to test Plasma 6.3. But how many people actually installed Plasma 6.3. Beta on top of Fedora 41 stable? Almost no one!!
Many people like me try Fedora Beta as soon as it’s out because it’s usually already in great shape and allows to get our hands on the newer kernel and hardware support sooner. Having the beta periods of Fedora and KDE overlapping was actually one of the most beneficial factors to smooth Plasma releases without major issues in Fedora 40 and Fedora 41. And let’s not forget KDE bugs are considered release blockers on Fedora! This bug with GCC compiler would very likely have been caught and fixed in a beta stage of Fedora! It’s no surprise to me that this time around the Plasma release was not as smooth.
