Many pre-release versions were made before the first final release was compiled on 14th November 1985. Below are the ones that are leaked and available online. Various unleaked versions are described on my blog.
Please note: I consider the Premiere Edition a pre-release version for several reasons. It predates the first official release (1.01), was never intended for a general release and also contains significant under the hood differences compared to 1.01 final.
