for those that like to use bibble for their post-processing, version 4.10 has just been released with some minor fixes and new cameras support:
Nikon D60, Canon Digital Rebel XSi (450D), Sony a200, a300, and a350, Pentax K20D and K200D, and Olympus E-420
They have also said that this will be the last release prior to the much awaited version 5
On the website, they have released some screen shots of Bibble 5 and it does look very promising. I certainly have been holding off making a decision between Bibble, Aperture and Lightroom. Looks like I'll be able to decide soon. They also have a section on their forums to discuss version 5. Go to the Bibble Labs site for your download of the latest version and to get a bit of a taste of version 5.
