I can only second that! It took me a while to work out the cause
of discrepancies in our case, and I've read the changelogs many times,
following up any mention of "breaking change" into the code to see if
it could have something to do with what we've observed.

We have skipped a version and it was a lot of work to isolate and fix this
issue as we initially thought it was down to other development work
that already happened and that required the latest version of boost.
If it was in the changelog we would have found it much sooner.

On the positive side, our tests are now much more robust to that sort
of changes. :)
