After much waiting, we can at last, say - DWR Version 2.0 has been released.
There are a lot of new features in version 2. Probably too many because it took a while, and it's going to take a few weeks for the documentation to catch-up. Version 1.0 and 1.1 had very good documentation, and we're determined not to let it slip.
Reverse Ajax particularly is doing a lot of very hard things. It has to cope with buggy browsers, buggy web-servers, buggy proxies, multi-threading, multiple languages, and the fact that the web was never designed to do this in the first place. There may be some bugs in the edge-cases, but we'll be fixing them soon. If you do find anything wrong, please report it.
