On Debian Testing today was a kernel update day! At 9:51am (Guelph time) I was still on kernel 4.17 😱

but at 9:53am, I was working with 4.18 🏆

By the way, the source code of the kernel is mirrored on Github, a repository without an issue section with a $\infty$ number of contributors 😂. Also, there is an exhaustive documentation available at https://www.kernel.org/doc/html/latest/.
