The release notes are great, but we don't rely on them for learning 
about API changes.  We rely on them as one source of information about 
features added in the release and use that information to guide 
prioritizing upgrades.

For API changes, I don't really expect those to be documented (and even 
if they were, they would be of relatively little benefit).  We learn 
about such changes when we perform upgrades.  When we see build 
failures, we research what changed and why, generally by looking at svn 
history.  In that respect, good comments on svn commits are extremely 
helpful.
