The next release of Ubuntu Linux is going to be called "Karmic Koala". Here is a list of features to look forward to:
One big change is that Empathy will be the new chat program (instead of Pidgin). Empathy supports audio and video chat.
Here's the full release schedule for Karmic Koala -- October 29th, 2009 is the planned date of the final release.
The alpha version is available for download here.
Is anyone here using the 9.04 Jaunty Jackalope release? I'm still on 8.10 Intrepid Ibex.
