When was a change installed?

[[[ whether defending the US Constitution against all enemies,     ]]]
[[[ foreign or domestic, requires you to follow Snowden's example. ]]]

When was the change to make lax whitespace mode the default
installed?

I can't find anything in the lisp/ChangeLog* files, which run through the start
of April.

Was it installed after that?  If so, how can I find out when?  There
is no ChangeLog file to search, now.
