[GENERAL] Which release does a commit end up getting into?

Hello all,

I'm keen on using the functionality in the commit dated Jan 2, 2017 below.

Probing the git repo however it exists only in the master branch and not tagged in a release.  The most recent release,
tagREL9_6_2, contains commits after Jan 2, but does not contain this commit.  The commit appears to have been inserted
intothe 2017-01 CommitFest [2]. 

How are commits filtered into releases?  i.e. when can we expect this commit to appear in a release?

Thank you,
John
