It would be nice to know what perceived problem they intended to fix in each case.

I know of one, which involves our typical SIs.

There's not a concise guide, but you can wade through the submissions from the 2011 ISAF Annual Conference to see where/why the rules were changed. http://www.sailing.org/meetings/archive/2011-conference.php#confpapers (Click on the "Submissions" tab and then scan down the "Relating To" column for racing rule references.)
