I was able to find the 720p 3GB torrent for this, along with STAR WARS and The Empire Strikes Back, but don’t know which version number it is. […]
Which version you have is shown after the end credits. After the last of the end credits scroll by, the screen fades to black and the music ends, wait about 5 seconds and the version information will appear.
[…] EDIT: For the Despecialized, STAR WARS is v2.5, The Empire Strikes Back and Return of the Jedi is MMXI. I’ll look for newer versions of the latter two.
MMXI is 2011 in roman numerals. That indicates it is v1.0
I don’t think ROTJ has an official version beyond 1.0 (yet. 2.0WP is not technically an official release.) But ESB 2.0 is out. You should get that while waiting for Harmy to finish up ESB v2.5.
