Release Notes

catchorg/Catch2 (catch2)

v3.15.1

Fixes

• Fixed potential OOB access when looking for start of broken UTF-8 sequence during linebreaking (#​3096)
• Fixed TEMPLATE_LIST_TEST_CASE_METHOD and CATCH_TEMPLATE_PRODUCT_TEST_CASE potentially causing ODR violations (#​3161)

v3.15.0

Fixes

• Fixed ambiguous overload issue with std::optional<T> in C++26. (#​3095)
  • Since std::optional was turned into a range, the partial specialization of StringMaker for range-like types and for std::optional<T> were in conflict.

Improvements

• Simplified CATCH_REGISTER_ENUM internals for faster compilation and retrieval.
• Successful assertion are slightly (1-2%) faster.
• Generic (new-style) matchers support constexpr matching in C++20.
  • Combining matchers requires C++26.
  • Catch2-provided generic matchers are all constexpr enabled.
• Added STATIC_REQUIRE_THAT for compile-time matcher assertions.
  • This requires the compiler to support enough constexpr for matchers, see above.

v3.14.0

Fixes

• Added missing <cstdint> includes. (#​3078)
• Fixed suppression of empty variadic macro arguments warning on Clang <19. (#​3085)
• Fixed catch_discover_tests failing during PRE_TEST discovery if a target does not have discoverable tests. (#​3075)
• Fixed build of the main library failing with CATCH_CONFIG_PREFIX_ALL defined. (#​3087)
• JUnit reporter outputs single failed (errored/skipped) assertion per test case. (#​1919)

Improvements

• The default implementation of --list-tags and --list-listeners has a quiet variant.
• Suppressed the new Clang warning about __COUNTER__ usage. (#​3076)
• Line-wrapping counts utf-8 codepoints instead of bytes. (#​1022, #​3086)
  • Combining character sequences are still miscounted, but Catch2 does not aim to fully support Unicode.

Code Review

This pull request updates the version of the catch2 Bazel dependency from 3.13.0 to 3.15.1 across multiple test projects, specifically in clwb/tests/projects/execution/MODULE.bazel, clwb/tests/projects/external_includes/MODULE.bazel, and clwb/tests/projects/simple/MODULE.bazel. There are no review comments to evaluate, and I have no additional feedback to provide on these changes.
