On the Symfony blog there's a new post briefly looking at Symfony 3 and what's different about it as compared to previous releases (and what's not).

Symfony 3.0.0 was released on November 2015 as planned by the Symfony 3 roadmap. As we do with any new Symfony version, we should publish a blog series explaining its new features.

However, Symfony 3.0 is a very special version which contains no new features comparing it with Symfony 2.8. Their only difference is that 3.0 removed any feature marked as deprecated in 2.8. That's why we won't publish any "New in Symfony 3.0" post. Instead, let's do a quick recap of the new Symfony 2.8 features which are also available on Symfony 3.0.

Among the items on their list are things like:

• New components like Guard Authentication and LDAP
• A MicroKernel component
• Improvements for VarDumper, Console and the Security components

Each of the changes on their list include links to get more information about the component and the post wraps up with a quick "how-to" on upgrading to Symfony 3 from other releases.
