I was expecting the updates to config to be included in 1.66.0.
How? Our release process was started before 15.5 was released, and the configuration changes are not especially trivial - and we're still without a volunteer running the regression tests for 15.5 so while I'm reasonably sure they don't break the libraries that depend on those macros since I tested before and after changes against develop, I confess I'm less sure what happens when we integrate everything to master. BTW, changes to config are just the tip of the iceberg: I suspect 15.5 in C++17 /permissive- mode will break quite a few libraries given that things that were in the std have now been removed. In short, have a complete Boost release that fully supports 15.5 requires quite a bit of work. In the mean time, I'm sure PR's against effected libraries would be welcome!
