The desktop photo management/editing tool has been available for Linux since 2006.
“As we continue to enhance Picasa, it has become difficult to maintain parity on the Linux version.” writes the search giant on its official blog.
“So today, we’re deprecating Picasa for Linux and will not be maintaining it moving forward.”
The ‘deprecation’ of the software doesn’t mean it’ll stop working; if you already have it installed you can continue to use it as normal.
But new features, bug fixes or any other update will be issues for the Linux version from today onwards.
