Re: [boost] [release] 1.66.0 closing for release on Wednesday

...

I'd like to merge a PR into master for fusion library, which fixes a regression on buggy (msvc) compiler.

https://github.com/boostorg/fusion/pull/162

Boost.regression shows the test was passed on develop. That looks okay. It looks like it changes behaviour for volatile types, but I assume that's intentional? Yes, the ctor should not be chosen for copying in the first place. The `disable_if` was added for fixing a bug in this beta, so I assume the change affects no existing user code.
