2.0 (alpha) is the current version.
The beta, which is currently in development, has no release date as of yet. I can tell you that steady progress is being made.
While there is no SSJ for 2.0, you can download the SSJ Script and the Red Saiyan Script for ESF.
You need The 5.0 and 5.1 script to run the Red Saiyan Script.
The latest release of the SSJ script is 5.5 and does not work with the Red Saiyan Script. SierraSonic should be updating the RSS to work with 5.5 shortly.
Both can be found at
