- Special Enhanced version Digitally Remastered with new exterior shots and remade opening theme song. Highlights include a new exterior shot of the starbase, complete with real people and vehicle traffic.
- A limited release theatrical version was screened in the US on 13 November 2007 and 15 November 2007 to promote the remastered version of the series. It included a message from Rod Roddenberry, a twenty-minute "making of" documentary about the restoration process, and a trailer for Season Two of the remastered series.
- Paramount's 1980 home video release is edited to present this episode and "The Menagerie, Part II(#1.12)" as one episode. The producer/writer credits are removed at the end of this episode, along with the closing credits on this version. The episode fades out quickly instead, and fades back in to Act I of "The Menagerie, Part II". The episode's 1981 RCA Selectavision Videodisc release, 1984 laserdisc release and 1985 VHS reissue restore this episode to its proper two-part format.
