The problem was introduced on Friday Jan 31, 20202, so has been around since Boost-1.73.

From my perspective, not fixing the bug in Histogram means that the wrong behaviour will remain in place for three more months, potentially affecting and angering more users when the behaviour will finally change in 1.76 (assuming that not many (new) users are going to check boost.org/patches). It the cost of delaying the release by a few days, I think it is worth it. If the cost involved is very large, then publishing the patch on http://boost.org/patches is a feasible solution, sure.

Ok. Many consumers use Boost Histogram through its Python wrapper and we can fix the bug there anyway (the Python wrapper is a separate project not tied to the Boost release cycle).
