New versions of symfony framework have been released last week. The 1.3.8 and 1.4.8 releases include a good number of fixes, 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. Please note that 1.3.7 and 1.4.7 were released also but included a bug in the development toolbar that got fixed in 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!
