Flag changes completed and described here:

The TL;DR version is that instead of having

--max-diff-block-lines affects single (--html) and child pages, in unpredictable ways
--separate-file-diff-size affects parent and child pages, in unpredictable ways

we now have 

--max-diff-block-lines affects single (--html) and parent pages, in the same way
--max-diff-block-lines-html-dir affects child pages
