# Revision History
:idprefix: changelog_
## Changes in 1.73.0
* Added support for `std::hash`, `boost::hash`.
* `variant<T...>` is now trivial when all types in `T...` are trivial.
This improves performance by enabling it to be passed to, and returned
from, functions in registers.
## Changes in 1.71.0
After the Boost formal review, the implementation has been
changed to provide the strong exception safety guarantee,
instead of basic. `expected` has been removed.
