Are there any production quality JSF 2 implementations yet?

java, jsf, jsf-2

Solution

There have always been two major JSF implementations: Sun Mojarra (the reference implementation) and Apache MyFaces. Mojarra 2.0 is already been final for months (since Oct 19, 2009). The MyFaces JSF 2.0 implementation is still on its way (is still Beta). No other JSF 2.0 implementations comes to mind.

Update: as of yesterday (Apr 21, 2010), MyFaces 2.0.0 finally became final.
