Is it known what build versions of the 2013 SDK this repository corresponds to?

[SC1040-TS2]

This question mostly applies to the SP codebase, but in the event the MP codebase found here also does not line up with the latest respective build release of 5394425, I would like some clarification on that as well.

for SP it corresponds to the engine binaries used in the Half-Life 2 series and Portal 1, and the upcoming branch of SDK Base 2013 Singleplayer
