The latest Linux Kernel 5.8 will be available via mainstream Linux distributions in Q3 and Q4 2020 releases this year. Overall, the Linux kernel 5.8 release introduces a bunch of driver support, security improvements, and optimizations.
Linux Kernel 5.8 is about the same size as Linux Kernel 4.9 from 2016 – over 22 million lines of code.
So I didn’t really expect this, but 5.8 looks to be one of our biggest releases of all time. In 5.8, we have no sign of those kinds of issues making the release bigger – there’s just simply a lot of development in there.
