0.2.25

• Added concept mbo::types::IsVariant.

0.2.22

• Changed the way mbo::types::Extend types are constructed to support more complex and deeper nested types.
• Provided a new mbo::extender::Default which wraps all default extenders.

  • Better ASAN compatibility for constexpr.

    • Option to suppress calling clear in the destructor for cases where that is not a constexpr.
    • Option to require presorted input: Allows much large constexpr LimitedSet/LimitedValue.
• Renamed types::AbslFormat to types::AbslStringify to better reflect its purpose.
• Changed types::AbslStringify to print field names prefixed with a fot '.' (requires Clang).

0.2.6

• Added a new comparator mbo::types::CompareLess which allows container optimizations.
• Moved most functionality of LimitedMap and LimitedSet to new base internal::LimitedOrdered.
