New versions of symfony framework have been released today. The 1.3.6 and 1.4.6 releases include a security vulnerability patch, check out the blog post announcing the release for more details. We recommend all our customers (and non-customers as well) to update their projects with the latest releases.
As always, all these new versions are already available on all our servers. If you are a VPS customer, make sure to update your local library to get the latest and greatest. And happy symfony coding!
