Seems a bit extreme.
Folks who want to continue to use C++03 can use boost version 1.68.0 or
the majority of libraries already. I thought there was agreement on the
mailing list that
boost was going to move forward, not just for the sake of moving forward,
but where it
makes sense to do so. I assume the 1.69.0 release notes will have a top
level item to
In reading this thread it sounds like a change was proposed, could possibly
backwards compatible or conditional with effort. For modifications to
as stated in the original email, most of the time folks leverage the
macros to make their changes conditional. It is up to the maintainer of
to decide if they want to continue to continue support C++03 or not at this
