Full Changelog: https://github.com/foonathan/type_safe/compare/v0.2.2...v0.2.3

• Replace TYPE_SAFE_ARITHMETIC_UB CMake option by TYPE_SAFE_ARITHMETIC_POLICY to enable checked arithmetic by default (#106)
• Be less strict in the signed/unsigned conversion of integer (#104)
• Various bugfixes (#97, #108, #111, #115)

This release is mainly bugfixes:

• Added explicit_bool strong typedef
• Fixed forwarding bug in with() of array_ref
• Silenced some warnings
• Improved CMake configuration

Version 0.2

This release took a long time, so here are just the most important changes.

• Added downcast() utility function
• Fixed GCC 4.8 and clang support
• Improved documentation
• Improved CMake and added Conan support
• Hashing support for boolean, integer, floating_point and strong_typedef

Vocabulary Types

• Added object_ref<T> and and xvalue_ref<T>
• Added array_ref<T>
• Added function_ref<T>
• Added flag_set<T>
• Breaking: renamed distance_t to difference_t
• Improved index_t and difference_t

Optional & Variant:

• Breaking: optional now auto-unwraps, removed unwrap() function
• Breaking: optional_ref creation function now opt_ref() instead of ref(), but more than before
• Breaking: Removed optional_ref<T>::value_or()
• Added optional_for<T> utility typedef
• Added support for additional parameters to with() and make it more optimizer friendly
• Added with() for tagged_union
• Improved map functions: additional arguments, member function pointers, void returning function objects
• Bugfix for trivial variant copy/move/destroy

Type Safe Building Blocks:

• Added pointer like access to constrained_type
• Added constrained_ref
• Added throwing_verifier for constrained_ref along with sanitize() helper functions
• Added literal operator to create a static bound of bounded_type
• Added bitwise operators for strong_typedef
• Added constexpr support to strong_typedef
• Added support for mixed operators in strong_typedef
• Made constrained_type constexpr
• Fixed strong typedef get() for rvalues
