After a long history of using mozillazine.org, the blog is now moving to http://blog.mozilla.com/calendar. The new location contains the same archive of posts available here so we don't have to worry about losing history.
Please update your bookmarks and feeds. If you are using planet.mozillamessaging.com to read this, you obviously don't have to do anything.
I'd like to thank everyone at mozillazine.org for kindly providing the blog hosting over the years. Also I'd like to thank everyone who has subscribed and I hope to see you at the new location!
