Linux kernel 2.6.27 was released last night by its father, Linus Torvalds - "So not a lot happened after -rc9, which is mostly good. I certainly don't want to have any upheavals at the end of an -rc series, although I wouldn't have minded more people looking at the regression list. That said, I think we're in pretty good shape, and it's not like I can hold back releases indefinitely anyway." The new version brings improved support for many webcams, lots of new drivers and many other interesting features.
It adds a new filesystem (UBIFS) for 'pure' flash-based storage, the page-cache is now lockless, much improved Direct I/O scalability and performance, delayed allocation support for ext4, multiqueue networking, data integrity support in the block layer, a function tracer, a mmio tracer, sysprof support, improved webcam support, support for the Intel wifi 5000 series and RTL8187B network cards, a new ath9k driver for the Atheros AR5008 and AR9001 chipsets, more new drivers, and many other improvements and fixes.
