Linus has released the 6.3 kernel as
expected.

It’s been a calm release this time around, and the last week was
really no different. So here we are, right on schedule, with the
6.3 release out and ready for your enjoyment.

That doesn’t mean that something nasty couldn’t have been lurking
all these weeks, of course, but let’s just take things at face
value and hope it all means that everything is fine, and it really
was a nice controlled release cycle. It happens.

Significant changes in this release include
the removal of a lot of obsolete Arm board files and drivers,
ongoing improvements to the (still minimal) Rust language support,
red-black trees for BPF programs,
ID-mapped mounts for tmpfs filesystems,
BIG TCP support for IPv4,
support for non-executable memfds,
the hwnoise
jitter-measurement tool,
and a lot more. See the LWN merge-window summaries
(part 1,2
part 2) and the (in-progress) KernelNewbies 6.3 page for
more information.
