Linus Torvalds announced yesterday the immediate availability of the 2.6.23 Linux kernel. This new release contains some tiny architecture changes for sparc64, mips and blackfin, some VFS/VM fixes, some networking fixes and miscellaneous driver fixes:
"Finally. Yeah, it got delayed, not because of any huge issues, but because of various bugfixes trickling in and causing me to reset my 'release clock' all the time. But it's out there now, and hopefully better for the wait,", stated Linus Torvalds in the release announcement.

The Linux Kernel is the essential part of all Linux Distributions, responsible for resource allocation, low-level hardware interfaces, security, simple communications, and basic file system management.
Linux is a clone of the Unix operating system, initially written from scratch by Linus Torvalds, assisted by a loosely-knit team of hackers across the Net. It aims to achieve POSIX and Single UNIX Specification compliance.
You can download the Linux kernel now from Softpedia.
