Linus has released the 5.14 kernel.

So I realize you must all still be busy with all the galas and
fancy balls and all the other 30th anniversary events, but at some
point you must be getting tired of the constant glitz, the
fireworks, and the champagne. That ball gown or tailcoat isn’t the
most comfortable thing, either. The celebrations will go on for a
few more weeks yet, but you all may just need a breather from them.

And when that happens, I have just the thing for you – a new kernel
release to test and enjoy.

Headline features in 5.14 include:
core scheduling (at last),
the burstable CFS bandwidth controller,
some initial infrastructure for BPF program
loaders,
the rq_qos
I/O priority policy,
some improvements to the
SO_REUSEPORT networking option,
the control-group “kill” button,
the memfd_secret() system call,
the quotactl_fd() system call,
and much more. See the LWN merge-window summaries (part 1, part 2) for more details.
