== The 2015 Christmas Special == 

 I've been reading the most recent issue of Doctor Who Magazine. It makes a note over the production blocks, including a note that the Christmas Special will be included in "the final production block". With the standard policy here of blindly following the DVDs regardless of how it is treated this is going to lead to complications. 

 Should we make a note that Block 9 is being used to film an episode not covered in this article? It's certainly noteworthy from a production standpoint and certainly isn't a unique case in Doctor Who's history (where other serials have been left to carry over for the next set of episodes).
