Just so everyone is perfectly clear, this upcoming sync has 5.15 becoming the LTS kernel but does NOT have 6.0 as the current kernel. That should (assuming nothing comes up) be happening in the following sync. Yes, that does mean that current and LTS will temporarily be the same version.
Also, KDE Plasma users can look forward to Plasma 5.26 in the upcoming sync (the 11/18 one).
