| The purpose of this page is tracking and explaining the features added in every release, just like the [http://wiki.dragonflybsd.org/index.php/DragonFly_Status Dragonfly people did]. | #pragma keywords Linux, Kernel, Operative System, Linus Torvalds, Open Source, drivers, filesystems, network, memory management, scheduler, preemtion, locking #pragma description Summary of the changes and new features merged in the Linux Kernel during the 2.6.x and 3.x development Changes done in each Linux kernel release. Other places to get news about the Linux kernel are [http://lwn.net/Kernel/ LWN kernel status], [http://www.h-online.com/open/features/ H-Online], or the Linux Kernel mailing list (there is a web interface in [http://www.lkml.org www.lkml.org]).

| It'd be nice if kernel hackers would spend some minutes adding their stuff here. The one place where you can find a comparable changelog are the fabulous LWN kernel articles: http://lwn.net/Kernel/ (without those we wouldn't be able to cover many old 2.6.x releases), or the [http://lwn.net/Articles/driver-porting/ driver porting guide] - but there's no reason why the kernel community shouldn't embrace and extend those efforts ;) | You can discuss the latest Linux kernel changes on the [http://forum.kernelnewbies.org/list.php?4 New Linux Kernel Features Forum]. |
