I just uploaded version 1.3, which doesn't have any major new features but corrects a number of small errors and annoyances. Thanks to everyone who reported bugs and contacted me to give feedback.
Contrary to the post below, Jureeka currently does not automatically update itself. You have to come back here (or to Mozilla) periodically to get the most recent version.
Once Jureeka gets out of the "sandbox" at Mozilla -- in other words, when people no longer have to register at Mozilla in order to download it -- automatic updates will be enabled. I'm awaiting word on when it can be released from the sandbox, and I'm hopeful that it will be soon.
