Linux Kernel 2.6.21 has been announced. Linus writes: "So the big change during 2.6.21 is all the timer changes to support a tickless system (and even with ticks, more varied time sources). Thanks (when it no longer broke for lots of people ;) go to Thomas Gleixner and Ingo Molnar and a cadre of testers and coders." More info here and here.

One of the bigger features of the 2.6.20 kernel was the kvm virtualization solution. One of the biggest features for 2.6.21 is the tickless kernel. It will improve energy efficiency and battery life among other times.
If you would rather not read through the shortlog, take a look here for a fairly comprehensive and easy to read list of changes:
