The first Picasa 2.7 for Linux public release candidate is now
available.
To get it, visit http://picasa.google.com/linux/download.html
and scroll down to the Beta section.

RELEASE NOTES:

This release includes the same new features as in Picasa 2.7 for
Windows
including, particularly, Picasaweb integration.
(See http://picasa.google.com/support/bin/answer.py?answer=53209. )

It also includes the following Linux-specific changes:

* Added amd64 Debian packages.
* New standard Linux folder name for My Photos
* Non-English language support enabled
* New Picasa Font Settings tool (for e.g. Asian users who need to
override
* Backup and Gift CD features now enabled, and create .iso files for
you to burn
* Lots of bug fixes

Known issues:

- Slideshow and Timeline still don't display full-screen unless your
display is set to 16 bits instead of the usual 24 or 32.

- Embedded web browser (used by e.g. the BlogThis! button) gives
some users trouble. We expect this will improve when we update to
the latest Wine. (No ETA on that yet, but we're already working on
it.)

- Video is still not supported.

- Running under Compiz or Beryl might not work well.  If you run
into trouble, please disable Compiz / Beryl when running Picasa.
This isn't a big surprise - Compiz is still fairly new - and we expect
it to improve with future releases of Compiz and/or Picasa.
