kernel trees

The 2.6.27.5 stable kernel update is available. "It contains a wide range of bugfixes, and all users of the 2.6.27 kernel series are strongly encouraged to upgrade.

Very strongly. Did I mention that you all should upgrade? Seriously, what are you waiting for? Running those old kernel trees prior to .27?

Are you crazy? You really want to run this one.

For many years, each Linux kernel release was assigned a series of three numbers, X.Y.Z, with an even Y indicating a "stable" release, and an odd Y indicating an "unstable" development release.

Z was incremented for each individual kernel release. The "stable" 1.0.0 Linux kernel was released in March of 1994.

New development was then continued in the "unstable" 1.1.z branch, until the "stable" 1.2.0 Linux kernel was release in March of 1995.

Major improvements in the kernel lead to X being incremented to 2, and a "stable" 2.0 kernel was released in June of 1996.
