[section:relnotes Release Notes]
[heading Boost Release 1.67]
* Fixed [@https://github.com/boostorg/optional/issues/46 issue #46].
* Fixed `-Wzero-as-null-pointer-constant` warnings.
[heading Boost Release 1.66]
* On newer compilers `optional` is now trivially-copyable for scalar `T`s. This uses a different storage (just `T` rather than `aligned_storage`). We require the compiler to support defaulted functions.
