I can never quite tell if Google considers its free Picasa image organizer/editor to be a Major Google Product–it doesn’t update it all that often, or promote it as energetically as it might. But it’s announcing Picasa 3.5 today, which should be available for Windows and OS X by the time you read this or soon thereafter. Google let me get my hands on it a bit early; Picasa fans should like it, and it gives those of us who haven’t checked out the app in a while new reason to revisit it.
