The story was included as part of a limited run box set in 2003 with "The Dalek Invasion of Earth" and "Resurrection of the Daleks". A remastered version of this story was released on Region 2 in November 2007, as part of "The Complete Davros Collection" and as a two-disc standalone release (including the 'Davros Connections' documentary from the boxset) on 20 July 2009. It includes the effects that were mistakenly left out and songs by The Beatles that weren't clearable for the original release but subsequently fall under a blanket music licensing agreement for the UK. There is also a newly remastered stereo and 5.1 surround sound mix. In the original Davros Boxset release version, there were two total mutes of the 5.1 soundtrack during episode one. 2entertain fixed the master within a few days of release and faulty copies could be exchanged for fixed ones via mail-in. The standalone version of the release uses the fixed version. The two-disc Special Edition was delayed due to clearance issues and was held off until it was released in the United States and Canada on 2 March 2010.
