On Friday there was an email from the Debian release Team to supply a standing update on the Debian Wheezy bugs and other problems. Ending the e-mail though was a surprise which was the codename announcement for Wheezy’s successor.

The Jessie codename comes somewhat as an upset as earlier this month Debian Zurg or Debian Shark were the doubtless contenders as the release to succeed “Wheezy” in an exceedingly few years time.
