Spoilers are precisely defined here. Rules vary by the story's medium. Info from television stories can't be added here until after the top or bottom of the hour, British time, closest to the end credits roll on BBC One. Therefore, fans in the Americas who are sensitive to spoilers should avoid Tardis on Sundays until they've seen the episode.
More notably, the magazine went through several format changes in this issue. The most obvious is the magazine size: previously at 29.5 by 21 centimetres, this issue changed the size to 28.5 by 22 centimetres. Additionally, all logos (such as that of "Beyond the TARDIS" and "Gallifrey Guardian") had been redesigned, some more radically than others. Certain features were also changed: "The Watcher's Guide to..." and "Ask DWM!" were both removed, while "Ask Steven Moffat" was added.
