DWR v 2.1 - Where can I find it

Hi All

I am having an issue passing (DWR-13) Arrays to a DWR call and found the following as a "Resolved" bug in DWR. Apperently this was fixed in  2.0.rc5 and  the DWR JIRA site talks about version 2.1, i am trying to find the updated version of DWR that I can download and fix this issue on my server.

Please help
