OMG! I do not understand this!
Updating now I see another kernel update.
Package (2) Old Version New Version Net Change Download Size
core/linux-lts 5.15.73-2 5.15.73-3 0.00 MiB 129.51 MiB
core/linux-lts-headers 5.15.73-2 5.15.73-3 0.00 MiB 25.93 MiB
By the way, as far as I learned here especially from @dalto. It is better to run LTS as it is more stable and more dubugged.
I am on LTS myself but having the other kernel just in case.
I see. Thank you for explaining.
Though I never seen any update for any software within just a couple of hours.
But I understand now. Accidents happen.
