I'd propose to have an extra paragraph at the end of the commit log
message.

         maintains the original blocking model by waiting on a mutex/condition
         variable pair while the hidden thread does all of the work.
     
    +    While the deprecated API used by the original were introduced in
    +    macOS 10.5 (Oct 2007), the API used by the updated code were
    +    introduced back in macOS 10.6 (Aug 2009) and has been available
    +    since then.  So this change _could_ break those who have happily
    +    been using 10.5 (if there were such people), but these two dates
    +    both predate the oldest versions of macOS Apple seems to support
    +    anyway, so we should be safe.
