+## Version detection
+
+Catch provides a triplet of macros providing the header's version, 
+
+* `CATCH_VERSION_MAJOR`
+* `CATCH_VERSION_MINOR`
+* `CATCH_VERSION_PATCH`
+
+these macros expand into a single number, that corresponds to the appropriate
+part of the version. As an example, given single header version v2.3.4,
+the macros would expand into `2`, `3`, and `4` respectively.

+# 2.1.2
+
+## Fixes
+* Fixed compilation error with `-fno-rtti` (#1165)
+* Fixed NoAssertion warnings
+* `operator<<` is used before range-based stringification (#1172)
+* Fixed `-Wpedantic` warnings (extra semicolons and binary literals) (#1173)
+
+
+## Improvements
+* Added `CATCH_VERSION_{MAJOR,MINOR,PATCH}` macros (#1131)
+* Added `BrightYellow` colour for use in reporters (#979)
+  * It is also used by ConsoleReporter for reconstructed expressions
+
+## Other changes
+* Catch is now exported as a CMake package and linkable target (#1170)
+
 # 2.1.1

 ```
 
+## Catch::is_range<T> specialisation
+As a fallback, Catch attempts to detect if the type can be iterated
+(`begin(T)` and `end(T)` are valid) and if it can be, it is stringified
+as a range. For certain types this can lead to infinite recursion, so
+it can be disabled by specializing `Catch::is_range` like so:
+
+```cpp
+namespace Catch {
+    template<>
+    struct is_range<T> {
+        static const bool value = false;
+    };
+}
+
+```
+
+
 ## Exceptions
 
 By default all exceptions deriving from `std::exception` will be translated to strings by calling the `what()` method. For exception types that do not derive from `std::exception` - or if `what()` does not return a suitable string - use `CATCH_TRANSLATE_EXCEPTION`. This defines a function that takes your exception type, by reference, and returns a string. It can appear anywhere in the code - it doesn't have to be in the same translation unit. For example:
