A comprehensible changelog of the Linux kernel, this page shows a summary of the important changes being added in each Linux kernel release - support for new devices, features, filesystems, and subsystems as well as important internal changes. While this text is aimed to be readable (unlike the full changelog), its primary audience is those who know a fair amount about how a kernel operates. Other places to get news about the Linux kernel are [http://lwn.net/Kernel/ LWN kernel status], [http://lwn.net/Articles/driver-porting/ LWN driver porting guide], [http://lwn.net/Articles/2.6-kernel-api/ LWN list of API changes in 2.6], or [http://www.lkml.org www.lkml.org]. If you're going to add something here look first at LinuxChangesRules!
