Picasa 2.7

The Picasa release notes report the following changes for the latest version of Picasa

Version 2.7, Build 36.37 - April 24, 2007

New RAW processing engine with support for more cameras and improved color.

New color engine for "tuning" fixes.

Added support for Google Photos Screensaver.

Improved BlogThis! reliability.

As generally happens with new releases, this is being rolled out slowly to existing users, and many users will not see a new update as available yet, either if they check in Picasa itself, nor if they use the Google Pack provided Google Updater.
