+## 3.15.2
+
+### Fixes
+* Fixed `--warn InfiniteGenerators` triggering even if the generator was limited to specific element via path filtering.
+* Fixed `-Wunused-parameter` triggering in `-fnoexceptions` builds.
+
+### Improvements
+* `catch_discover_tests` can handle cases where the binary prints out non-Catch2 output due to global constructors (#3162)
+
+
 ## 3.15.1
