+## 2.13.5
+
+### Improvements
+* Detection of MAC and IPHONE platforms has been improved (#2140, #2157)
+* Added workaround for bug in XLC 16.1.0.1 (#2155)
+* Add detection for LCC when it is masquerading as GCC (#2199)
+* Modified posix signal handling so it supports newer libcs (#2178)
+  * `MINSIGSTKSZ` was no longer usable in constexpr context.
+
+### Fixes
+* Fixed compilation of benchmarking when `min` and `max` macros are defined (#2159)
+  * Including `windows.h` without `NOMINMAX` remains a really bad idea, don't do it
+
+### Miscellaneous
+* `Catch2WithMain` target (static library) is no longer built by default (#2142)
+  * Building it by default was at best unnecessary overhead for people not using it, and at worst it caused trouble with install paths
+  * To have it built, set CMake option `CATCH_BUILD_STATIC_LIBRARY` to `ON`
+* The check whether Catch2 is being built as a subproject is now more reliable (#2202, #2204)
+  * The problem was that if the variable name used internally was defined the project including Catch2 as subproject, it would not be properly overwritten for Catch2's CMake.
