The 5.5-rc6 kernel prepatch is out for testing. "Let's see how things go. I do suspect that this ends up being one of those 'rc8' releases, not because things look particularly bad right now, but simply because the holiday season has meant that both the testing side and the development side have been quiet. But who knows?"
On the stable side, 5.4.11, 4.19.95, 4.14.164, 4.9.209, and 4.4.209 have all been released with another set of important fixes.
