Kernel release status

[Posted January 29, 2020 by corbet]

The 5.5 kernel was released on January 26; Linus wrote that he had decided another -rc release wasn't needed. "So despite the slight worry that the holidays might have affected the schedule, 5.5 ended up with the regular rc cadence and is out now." Some of the significant features in this release are iopl() emulation, many new io_uring commands, live-patch state tracking, type checking for BPF tracepoint programs, a new CPU load-balancing algorithm, the KUnit unit-testing framework, airtime queue limits for WiFi, and much more. See the KernelNewbies 5.5 changelog for more information.

Stable updates: 5.4.14, 4.19.98, 4.14.167, 4.9.211, and 4.4.211 were released on January 23, followed by 5.4.15, 4.19.99, and 4.14.168 on January 27.

The 5.4.16, 4.19.100, 4.14.169, 4.9.212, and 4.4.212 updates are in the review process; they are due on January 30.
