"We're happy to announce the launch of Picasa 3.5, the latest release of Picasa photo management software. If you don't want to wait until we autoupdate everyone to Picasa 3.5, you can download it at picasa.google.com. This ReadMe page appears when a new version of Picasa software is available, and tells you what changes and improvements are in each release."
Picasa is, bar none, the best free photo organizer tool there is on the market today - it rivals and surpasses some of the $100+ software I've seen. Google continues to invest in improving the program, which is great to see. I was worried for a while there, but Google evidently sees value in having such a great piece of software in their portfolio. If you haven't checked Picasa out, you really should!
