Key Highlights of Linux Kernel 6.13 RC7
1. Increased Activity After the Holiday Slowdown
While the development pace slowed during the holiday season, activity picked up last week. RC7 is slightly larger than average, but the changes are in line with expectations for this stage of the development cycle.
In the 6.13-rc7 announcement mail, Torvalds wrote:
[…]
This rc7 is slightly bigger than normal, but considering the timing,
it's pretty much where I would have expected, and nothing really
stands out. The diffstat looks fine, and the appended shortlog doesn't
look strange either.
