Changes

v0.2 (in progress)

New features

Interleave skipped and failed tests in their original order in the summary log
Capturing large arrays of trivial types for matchers is now much faster
expect now takes a universal reference for the value to test to support matchers which need access to non-const objects (e.g. to call a non-const member function)
New matchers in_interval and exception_what
Add support for char8_t

Bug fixes

Test failures across multiple runs are now correctly grouped in the summary results
bencode.hpp is now installed alongside mettle when --vendorize is used
Arithmetic matchers now use ADL to find max and abs, allowing custom arithmetic types to use their own implementations of these functions
Print strings with unusual character types as an array of characters

Breaking changes

Implementation updated to require C++20
make_matcher helper has been removed; use basic_matcher directly instead
METTLE_EXPECT macro has been removed; use expect instead

v0.1 (2019-11-29)

Initial release
Support for defining assertions via composable matchers
Tests can be groups into suites/subsuites, which can additionally be parameterized by type or value
Allow aggregating the output of multiple test executables via the mettle driver
