Another very cool new feature is called Face Movie. If you have been tagging the faces of people in your photos, you can have Picasa automatically generate a slideshow centered around that person. Picasa aligns the face of the featured person as it transitions through all the photos in the slideshow, creating a very striking effect. This feature is definitely worth checking out, and I can see it coming in very handy when you want to put something together quickly for a special event. Check out the Face Movie demo on YouTube if you want to see an example before trying it on your own pictures.
I know a lot of you will be happy to hear that Picasa now has improved its support for XMP and EXIF metadata. Now you can see camera settings information in the properties panel, and Picasa will read color space information from the metadata and display your pictures more accurately on-screen.
Batch upload functions have also been added in this version so you can upload multiple albums at the same time. You can also remove online albums, and edit properties for your online photos such as size, visibility, and sync state.
According to the Google Photos Blog, some additional under-the-hood improvements are also a part of this update. Although the Picnik integration is a bit disappointing, you don't have to use it, and the other new features are certainly worth taking the time to update to Picasa 3.8.
