F-Spot was the default photo manager for Ubuntu until 10.10 when it will be replaced with Shotwell.
F-Spot 0.8.0 was released 2 days ago with a complete new import system, improved duplicate detection, photo panning using the mouse as well as other features which you can see by reading the official F-Spot 0.8.0 release announcement. Further more, the new version also fixes almost 300 bugs!
If you're using Ubuntu 10.04 Lucid Lynx, you're probably noticed the F-Spot PPA hasn't been updated yet (and I'm guessing it will take a while until F-Spot 0.8.0 will be in the PPA as it usually takes quite some time). But Roberto @ LFFL created some F-Spot 0.8.0 Ubuntu 10.04 Lucid Lynx .deb files so you can install it already.

Thanks to Roberto for the debs!
