I obviously made a mistake. I don’t know now where I identified CU182 as going to be 6.1.62
I have looked through the testing announcement and the git repo and there is no mention of 6.1.62
Because the kernel developers have moved on from the 6.1 Long Term Release kernel series to the 6.6 Long Term Release kernel series.
As Core Update 183 has been in unstable mode for a while the 6.6 series has already had several version updates.
6.6.2 was merged into the IPFire git repo on 5/12/2023 and versions 6.6.3, 6.6.4, 6.6.5, 6.6.6, 6.6.8, 6.6.9, 6.6.10 and 6.6.11 have been merged into the git repo from that date until yesterday.
I am not sure that I understand what you mean with this question.
IPFire does not have a git repo on the kernel git repo.
IPFire has its own git repo and the kernel source is used as part of that git repo.
