[heading Boost Release 1.87]
* *Breaking change.* Dropped support for C++03. C++11 is now the required minimum.
* *Breaking change.* Dropped support for C++03. C++11 is now the required minimum; at least some C++11 features.
* Dropped dependency on Boost.Utility.
* Dropped dependency on Boost.Predef.
* Dropped dependency on Boost.StaticAssert.
* Dropped dependency on Boost.Move.
* A bit faster implementation of some relational operations.
* Tags `in_place_init` and `in_place_init_if` become `inline constexpr` and therewith leave smaller footprint in the executable. This addresses [@https://github.com/boostorg/optional/issues/103 issue #103].
