Microsoft change the certifications as and when they want.
2012/2014 had a generic MCSA as they combined the tracks for MCSA, with specific MCSE's so you had to do a bit of development (461), administration (462) or BI (463) before you could do the specific MCSE in the corresponding topic.
2016 they have split out the MCSA certification tracks like the 2008 certs, into Administration / Development / BI, so 461 is part of the Development 2016 MCSA
Wouldn't be surprised if they combine them again for the next revision of the certification.
