The developers of pfSense have released the BETA version for 2.2.
The 2.2 release has now reached the beta milestone. This means the release is feature complete, a comprehensive list of new features and changes can be found here, and should stay relatively stable throughout the remainder of the development process. That’s not to say it’s production ready though, our developers are using it in production and have been for months, but unless you have a solid understanding of the underlying system and can manually verify the configuration, 2.2 is not yet for you (young padawan).
If you have a non-critical environment where you can try it out, you can find the latest build on the snapshot server. Please report your experiences on the 2.2 board on the forum. Note that snapshots have the risk of changes being made in the source very frequently, and you may get a snapshot from a point in time that caught part but not all of certain changes.
