+# 1.9.5
+
+### Fixes
+* Truthy expressions are now reconstructed properly, not as booleans (#914)
+* Various warnings are no longer erroneously suppressed in test files (files that include `catch.hpp`, but do not define `CATCH_CONFIG_MAIN` or `CATCH_CONFIG_RUNNER`) (#871)
+* Catch no longer fails to link when main is compiled as C++, but linked against Objective-C (#855)
+* Fixed incorrect gcc version detection when deciding to use `__COUNTER__` (#928)
+  * Previously any GCC with minor version less than 3 would be incorrectly classified as not supporting `__COUNTER__`.
+* Suppressed C4996 warning caused by upcoming updated to MSVC 2017, marking `std::uncaught_exception` as deprecated. (#927)
+
+### Improvements
+* CMake integration script now incorporates debug messages and registers tests in an improved way (#911)
+* Various documentation improvements

 * `console` writes as lines of text, formatted to a typical terminal width, with colours if a capable terminal is detected.
 * `compact` similar to `console` but optimised for minimal output - each entry on one line
-* `junit` writes xml that corresponds to Ant's [junitreport](http://help.catchsoftware.com/display/ET/JUnit+Format) target. Useful for build systems that understand Junit. 
+* `junit` writes xml that corresponds to Ant's [junitreport](http://help.catchsoftware.com/display/ET/JUnit+Format) target. Useful for build systems that understand Junit. If you are using Jenkins with Catch 1.x, you can improve quality of output by applying changes in [#923](https://github.com/philsquared/Catch/pull/923).
 Because of the way the junit format is structured the run must complete before anything is written. 
 * `xml` writes an xml format tailored to Catch. Unlike `junit` this is a streaming format so results are delivered progressively.
