"New filesystem support, security and driver
improvements are all part of the new Linux 2.6.30 kernel release,
although one of the most noticeable elements in the new release is
the kernel inclusion of fastboot, an enhancement designed to speed
startup for Linux-based systems.
"Linux 2.6.30 also marks a step back, reinaugurating Tux the
penguin as its official mascot after a one-release hiatus, during
which Tuz the Tasmanian devil held the reins as a effort to raise
awareness around the plight of the Tasmanian devil."
