 The advantage of this format is that it corresponds well to the way Catch works (especially the more unusual features, such as nested sections) and is a fully streaming format - that is it writes output as it goes, without having to store up all its results before it can start writing.
 
-The disadvantage is that, being specific to Catch, no existing build servers understand the format natively. It can be used as input to an XSLT transformation that could covert it to, say, HTML - although this loses the streaming advantage, of course.

 Catch works quite nicely without any command line options at all - but for those times when you want greater control the following options are available.

 ## Adding your own command line options
 
-Catch embeds a powerful command line parser which you can also use to parse your own options out. This capability is still in active development but will be documented here when it is ready.
+Catch embeds a powerful command line parser called [Clara](https://github.com/philsquared/Clara). 
+As of Catch2 (and Clara 1.0) Clara allows you to write _composable_ option and argument parsers, 
+so extending Catch's own command line options is now easy.

+#define CATCH_CONFIG_RUNNER
+#include "catch.hpp"
+
+int main( int argc, char* argv[] )
+{
+  Catch::Session session; // There must be exactly one instance
+  
+  int height = 0; // Some user variable you want to be able to set
+  
+  // Build a new parser on top of Catch's
+  auto cli 
+    = session.cli() // Get Catch's composite command line parser
+    | Opt( height, "height" ) // bind variable to a new option, with a hint string
+        ["-g"]["--height"]    // the option names it will respond to
+        ("how high?");        // description string for the help output
+        
+  // Now pass the new composite back to Catch so it uses that
+  session.cli( cli ); 
+  
+  // Let Catch (using Clara) parse the command line
+  int returnCode = session.applyCommandLine( argc, argv );
+  if( returnCode != 0 ) // Indicates a command line error
+  	return returnCode;
+
+  // if set on the command line then 'height' is now set at this point
+  if( height > 0 )
+      std::cout << "height: " << height << std::endl;

 ## Breaking changes
 * Removed C++98 support
@@ -17,6 +17,19 @@
 * `*_THROWS_AS(expr, exception_type)` now unconditionally appends `const&` to the exception type.
 * `CATCH_CONFIG_FAST_COMPILE` now affects the `CHECK_` family of assertions as well as `REQUIRE_` family of assertions
   * This is most noticeable in `CHECK(throws())`, which would previously report failure, properly stringify the exception and continue. Now it will report failure and stop executing current section.
+* Removed deprecated matcher utility functions `Not`, `AllOf` and `AnyOf`.
+  * They are superseded by operators `!`, `&&` and `||`, which are natural and do not have limited arity
+* Removed support for non-const comparison operators
+  * Non-const comparison operators are an abomination that should not exist
+  * They were breaking support for comparing function to function pointer
+* `std::pair` and `std::tuple` are no longer stringified by default
+  * This is done to avoid dragging in `<tuple>` and `<utility>` headers in common path
+  * Their stringification can be enabled per-file via new configuration macros
+* `Approx` is subtly different and hopefully behaves more as users would expect
+  * `Approx::scale` defaults to `0.0`
+  * `Approx::epsilon` no longer applies to the larger of the two compared values, but only to the `Approx`'s value
+  * `INFINITY == Approx(INFINITY)` returns true

 ## Fixes
+* Don't use console colour if running in XCode
+* Explicit constructor in reporter base class
+* Swept out `-Wweak-vtables`, `-Wexit-time-destructors`, `-Wglobal-constructors` warnings
+* Compilation for Universal Windows Platform (UWP) is supported

 ## Where to put it?
 
-Catch is header only. All you need to do is drop the file(s) somewhere reachable from your project - either in some central location you can set your header search path to find, or directly into your project tree itself! This is a particularly good option for other Open-Source projects that want to use Catch for their test suite. See [this blog entry for more on that](http://www.levelofindirection.com/journal/2011/5/27/unit-testing-in-c-and-objective-c-just-got-ridiculously-easi.html).
