No, the change wasn't entirely unobtrusive, a few wrinkles had to be ironed
out.

If you insist, I don't mind discussing the initial deployment of Boost
Exception, but perhaps it'd be a better use of everyone's time to stick to
the present.

Obviously libraries change. The important thing is to keep changes
compatible with existing code.

The "new" (several years old now) boost::throw_exception functionality is
100% compatible with the original.

FYI, there was no BOOST_THROW_EXCEPTION before Boost Exception.

What he means is that BOOST_THROW_EXCEPTION is preferable to
boost::throw_exception, because it allows more complete messages by
boost::diagnostic_information.
