Earlier this year, I was working on lots of performance metrics of CMake
and this was part of it. There ended up being more than a dozen branches
resulting from that work (some of them still unmerged). Doing some
digging shows that this is where the commit finally hit master:

    commit bd20dd6b8a925a421167602027fff9b904fd0822
    Merge: b041fc1 e17a69b
    Author: Brad King <brad.king at kitware.com>
    Date:   Thu Jun 12 11:28:44 2014 -0400

so June looks right.
