Symfony 2.0.13 has just been released.

The CHANGELOG has all the details about the changes and you can even have a look at the full diff.

If you are starting a new project, you can get the Symfony Standard Edition distribution on the download page.

If you already have a project based on the Symfony Standard Edition 2.0.x, you can easily upgrade to 2.0.12 by getting the new deps and deps.lock files.

Then, run the vendors script (it also clears your cache):

$ ./bin/vendors install

Remember that the Symfony2 Components are also available as standalone libraries. You can get them via their dedicated read-only repositories on Github (https://github.com/symfony/Finder for instance), install them via PEAR (pear install symfony2/Finder), or even install them via Composer.
