    * criterion: version 2.5.0
    * Addition: added --default-timeout CLI switch to set a fallback timeout
      for tests that have no timeout set. Unlike --timeout, which caps the
      timeout of every test, explicitly timed tests are left untouched
      (Matéo LE FLEM).
    * Addition: added --show-skipped CLI switch to show the number of skipped
      tests in the synthesis line.
    * Breaking: ABI incompatibility with prior versions of criterion. You
      **must** recompile your tests.
    * Change: cr_get_redirected_stdout(), cr_get_redirected_stderr() and
      cr_get_redirected_stdin() (and their C++ counterparts) now return a
      stream owned by the caller, who is responsible for closing it.
      Closing that stream no longer interferes with the standard stream
      assertions.
    * Change: the standard stream assertions (cr_assert_stdout_eq_str and
      friends) now flush the stream before comparing its contents, so tests
      no longer need to fflush() or disable buffering beforehand. Each
      assertion consumes the output written since the previous one.
    * Fix: fixed crash when a standard stream assertion was used more than
      once in a test, or when the test wrote to the stream after asserting
      on it.
    * Fix: standard stream assertions now fail with an explicit message
      instead of hanging when the stream was never redirected.
    * Fix: fixed any() only passing when its last operand was true
      (Ray Chern).
    * Fix: fixed result propagation of nested assertion combinators, and
      not() being ignored when applied to another combinator.
    * Fix: sibling assertion combinators, like all(any(...), any(...)), now
      compile.
    * Fix: failing not() and none() operands were reported with
      "<no difference -- this is a user bug in the object stringifier>"
      instead of their values. Failing combinators now also print a header
      line above their failing operands.
    * Fix: assertion failures whose value diff is empty (because the user
      stringifier produced the same output for different values) now print
      the raw actual and expected values instead of a generic message.
    * Fix: fixed plain expressions in the new assertion API failing when
      they evaluated to a non-zero value other than 1, like
      cr_assert(flags & 4).
    * Fix: plain expressions starting with an operator, a literal or a cast
      can now be passed to the new assertion API by wrapping them in an
      extra pair of parentheses, like cr_assert((!x)).
    * Fix: fixed undefined behavior (null pointer arithmetic, reported by
      UBSan) when computing the length of array type tags in the new
      assertion API.
    * Fix: fixed multiple definition errors when ReportHook was used on the
      same line in different files, or several times in one macro
      (Cade-Peterson).
    * Fix: tests, suites, parameterized tests and report hooks are no
      longer discarded by the linker when building with optimizations or
      --gc-sections (Jerry James).
    * Fix: the cleanup function of parameterized tests was called as soon
      as the last test worker had been spawned rather than after all
      workers exited, which crashed with --jobs > 1.
    * Fix: skipped tests with an expected .signal or .exit_code are no
      longer reported as failed.
    * Fix: criterion::allocator no longer uses std::allocator<void>, which
      is deprecated in C++17 and removed in C++20.
    * Misc: the build system now detects a system-wide klib installation
      instead of always falling back to the wrap.
    * Misc: replaced the discontinued Cirrus CI; FreeBSD, macOS (x86-64) and
      Windows are tested on GitHub Actions again.
    * Misc: fixed the extraction of translatable messages and updated the
      German and French translations.
    * Misc: various documentation fixes.
    * Misc: various build system fixes.
    * Misc: various updates to dependencies.

2023-04-29  Franklin "Snaipe" Mathieu  <franklinmathieu@gmail.com>

    * criterion: version 2.4.2
    * Fix: fixed crash in assert failure reporting when there was no diff.
      If the user-provided function to stringify an object was bugged and
      produced equal output for non-equal objects, thus producing an empty
      diff, Criterion crashed trying to access an unset parameter list.
    * Fix: fixed crashing tests when Criterion was compiled with nanopb>=0.4.7
      (Balazs Scheidler).
    * Fix: fixed deadlock when test timeout was specified and the system was
      overloaded.
    * Fix: fixed segfault if map_shdr fails (David Gloe).
    * Fix: fixed memory leak on test failure (Jookia).
    * Fix: fixed gt() and ge().
    * Fix: escape XML/JSON reports.
    * Misc: converted klib and debugbreak submodules to subprojects
      (Cristian Prieto).
    * Misc: various documentation fixes (Yuri Victorovich, Jonas Schulze).
    * Misc: various updates to dependencies.

2022-04-13  Franklin "Snaipe" Mathieu  <franklinmathieu@gmail.com>

    * criterion: version 2.4.1
    * Fix: compiling tests with link-time-optimization no longer causes
      the tests to not get detected and run.
    * Fix: theories now correctly iterate through the argument matrix. This
      manifested as theories running the expected number of times, but
      always using the first possible combination of parameters.
    * Fix: fixed leak due to not calling git_libgit2_shutdown. This should
      appease valgrind and the address sanitizer.
    * Misc: added suggestion to run ldconfig in installation documentation
      (Gerald Senarclens de Grancy).

2022-01-03  Franklin "Snaipe" Mathieu  <franklinmathieu@gmail.com>

    * criterion: version 2.4.0
    * Addition: added new experimental assertion API. The API brings a more
      generic approach for comparing values of arbitrary types, alongside
      value diffing on error.
    * Addition: added --color=<always|never|auto> CLI switch to explicitly
      add or strip colors from the test runner output.
    * Addition: added --encoding CLI switch to control the use of unicode
      in the test runner output.
    * Addition: added ARM (v6/v7) and ARM64 support. Huge kudos to László
      Várady (MrAnno) for fixing most of the issues and testing on real
      hardware.
    * Addition: added directory support to write test reports via --output.
      If the provided path is an existing directory, the report will be
      created in that directory, and the report file is named after the
      binary (László Várady).
    * Addition: added support for setting RPATH for pkg-config users
      (-Drpath-in-pkgconfig=enabled).
    * Breaking: the runner now exits with a non-zero exit status on warning
      by default. --ignore-warnings has been added to restore the old behaviour.
    * Breaking: changed '-' to mean stdout rather than stderr.
      /dev/stderr can instead be used to signify stderr, even on Windows.
    * Breaking: switched build system from CMake to Meson.
    * Deprecation: --ascii and CRITERION_USE_ASCII are deprecated in favor of
      passing --encoding=C or setting LC_ALL=C.
    * Fix: fixed c++ allocator to work with older compiler versions.
    * Fix: fixed CRITERION_DISABLE_TIME_MEASUREMENTS=1 not being picked up.
    * Fix: allow log functions to be called from runner-side report hooks.
    * Fix: allow assertions to execute in fixtures (init/fini).
    * Fix: test std{out,err} is now discarded when operating in quiet mode.
      They are also discarded when the runner output is redirected via
      --output.
    * Fix: cr_file_match_str now fails if the input is longer than the
      expected value (Ethiraric).
    * Fix: cr_file_match_str passes when both the input and expected value
      are empty (Ethiraric).
    * Fix: fixed throw assertion not failing when nothing throws.
    * Fix: fixed major slowdowns from running criterion in container
      environments with a high open file descriptor limit.
    * Fix: fixed libcriterion.so not being loadable on WSL due to the stack
      not being executable.
    * Fix: worked around msync not properly working on WSL and causing the
      runner to break.
    * Fix: fixed use-after-free in fprintf_locale.
    * Fix: fixed cr_file_match_file matching only the last block (Ethiraric).
    * Fix: fixed TAP test description format. TAP mandates that details must
      use a YAML format, while Criterion directly dumped the description
      string in the detail section.
    * Fix: fixed TAP output to comment out blank lines, since the TAP spec
      doesn't say anything about blank lines, and some parsers have trouble
      with them.
    * Fix: fixed c++20 incompatibility with the criterion allocator (Ersikan).
    * Fix: fixed escape of special characters in XML output (Paul Khuat-Duy).
    * Fix: fixed crash when passing an empty string to cr_log_info (Ersikan).
    * Fix: fixed compilation errors on macOS (Kare Nuorteva, László Várady).
    * Fix: fixed --debug flag aborting runner with gdbserver >= 8.3.
    * Fix: fixed gdb stepping issue with '--debug' on macOS (Apple silicon).
    * Misc: various documentation fixes (Oleksii Vilchanskyi, Sam Zaydel, Karim
      Dridi, Florent Poinsard, Tim Gates, László Várady, Japroz Saini).
    * Misc: various updates to dependencies (László Várady).
    * Misc: various build system fixes (Tomasz Sieprawski, László Várady).
    * Misc: various fixes to the autotools example (Bruno Belany).
    * Misc: from now on, --debug will fall back to the idle method in case no
      debugger can be found.

2018-11-05  Franklin "Snaipe" Mathieu  <franklinmathieu@gmail.com>

    * criterion: version 2.3.3
    * Fix: Clang 5.0.x was producing test executables that caused Criterion to
      fork-bomb the host system. The issue has been fixed, and Criterion
      now pro-actively aborts itself if it detects a fork-bomb loop to avoid
      similar issues in the future.

2016-12-07  Franklin "Snaipe" Mathieu  <franklinmathieu@gmail.com>

    * criterion: version 2.3.0-1
    This is a re-release of v2.3.0.

    There are no substantial changes in the release, only fixes in the build
    system. If you are not building criterion from source, you can ignore this
    changelog.

    * Fix: Updated version strings in messages
    * Fix: The build system now searches for local installations of non-criterion-specific dependencies.

2015-12-08  Franklin "Snaipe" Mathieu  <franklinmathieu@gmail.com>

    * criterion: version 2.2.0
    * Breaking: Renamed all unprefixed internal macros and functions that were

2015-09-14  Franklin "Snaipe" Mathieu  <franklinmathieu@gmail.com>

    * criterion: version 2.0.0
