+## 3.8.1
+
+### Fixes
+* Fixed bug where catch_discover_tests fails when no TEST_CASEs are present (#2962)
+* Fixed Clang 19 -Wc++20-extensions warning (#2968)
+
+
+## 3.8.0
+
+### Improvements
+* Added `std::initializer_list` overloads for `(Unordered)RangeEquals` matcher (#2915, #2919)
+* Added explicit casts to silence GCC's `Wconversion` (#2875)
+* Made the use of `builtin_constant_p` tricks in assertion macros configurable (#2925)
+  * It is used to prod GCC-like compilers into providing warnings for the asserted expressions, but the compilers miscompile it annoyingly often.
+* Cleaned out Clang-Tidy's `performance-enum-size` warnings
+* Added support for using `from_range` generator with iterators with `value_type = const T` (#2926)
+  * This is not correct `value_type` typedef, but it is used in the wild and the change does not make the code meaningfully worse.
+
+### Fixes
+* Fixed crash when stringifying pre-1970 (epoch) dates on Windows (#2944)
+
+### Miscellaneous
+* Fixes and improvements for `catch_discover_tests` CMake helper
+  * Removed redundant `CTEST_FILE` param when creating the indirection file for `PRE_TEST` discovery mode (#2936)
+  * Rewrote the test discovery logic to use output from the JSON reporter
+    * This means that `catch_discover_tests` now requires CMake 3.19 or newer
+  * Added `ADD_TAGS_AS_LABELS` option. If specified, each CTest test will be labeled with corresponding Catch2's test tag
+* Bumped up the minimum required CMake version to build Catch2 to 3.16
+* Meson build now provides option to avoid installing Catch2
+* Bazel build is moved to Bzlmod.
+
+
+## 3.7.1
+
+### Improvements
+* Applied the JUnit reporter's optimization from last release to the SonarQube reporter
+* Suppressed `-Wuseless-cast` in `CHECK_THROWS_MATCHES` (#2904)
+* Standardize exit codes for various failures
+  * Running no tests is now guaranteed to exit with 2 (without the `--allow-running-no-tests` flag)
+  * All tests skipped is now always 4 (...)
+  * Assertion failures are now always 42
+  * and so on
+
+### Fixes
+* Fixed out-of-bounds access when the arg parser encounters single `-` as an argument (#2905)
+
+### Miscellaneous
+* Added `catch_config_prefix_messages.hpp` to meson build (#2903)
+* `catch_discover_tests` now supports skipped tests (#2873)
+  * You can get the old behaviour by calling `catch_discover_tests` with `SKIP_IS_FAILURE` option.
