Canonical this afternoon debuted its Ubuntu 9.04 release of Linux, the tenth release since the company founded the Ubuntu project in October 2004. This iteration of Ubuntu, code-named "Jaunty Jackalope," comes with mixes designed specifically for three platforms: netbooks, desktops, and servers.
The boot time for the operating system has also been dramatically reduced from 45 seconds down to 25 seconds.

However there is an error where it states...
"Ubuntu is a normal release, meaning that it will eventually be replaced by Ubuntu 10.09 eighteen month from now (in October 2010)."
...as with a normal release 18 months is the support time, and it will be replaced with Ubuntu 9.10 Karmic Koala in October.
Lastly - give it a month after the introduction date to both let the enthusiasts find the bugs, and to get a download that wont take ages.
