Play 2.0 is out. But it's got a curfew.
According to the movie trailers, "Play 2.0 is still under heavy development and APIs are likely to change, but you can already have a look and download the preview version."
But having said that, Play keeps gaining traction in the industry. Over the past couple of years, we're seeing more and more people talking about Play and Vaadin in our surveys. Clearly the community hasn't hit the saturation point.
So, if you're up for learning another framework, check out Play. Lots of smart and handsome people seem to be adopting it.
