Fixes #1285

+Catch
+-----
+
+This module defines a function to help use the Catch test framework.
+
+The :command:`catch_discover_tests` discovers tests by asking the compiled test
+executable to enumerate its tests.  This does not require CMake to be re-run
+when tests change.  However, it may not work in a cross-compiling environment,
+and setting test properties is less convenient.
+
+This command is intended to replace use of :command:`add_test` to register
+tests, and will create a separate CTest test for each Catch test case.  Note
+that this is in some cases less efficient, as common set-up and tear-down logic
+cannot be shared by multiple test cases executing in the same instance.
+However, it provides more fine-grained pass/fail information to CTest, which is
+usually considered as more beneficial.  By default, the CTest test name is the
+same as the Catch name; see also ``TEST_PREFIX`` and ``TEST_SUFFIX``.
+
+.. command:: catch_discover_tests
+
+  Automatically add tests with CTest by querying the compiled test executable
+  for available tests::
+
+    catch_discover_tests(target
+                         [TEST_SPEC arg1...]
+                         [EXTRA_ARGS arg1...]
+                         [WORKING_DIRECTORY dir]
+                         [TEST_PREFIX prefix]
+                         [TEST_SUFFIX suffix]
+                         [PROPERTIES name1 value1...]
+                         [TEST_LIST var]
+    )
+
+  ``catch_discover_tests`` sets up a post-build command on the test executable
+  that generates the list of tests by parsing the output from running the test
+  with the ``--list-test-names-only`` argument.  This ensures that the full
+  list of tests is obtained.  Since test discovery occurs at build time, it is
+  not necessary to re-run CMake when the list of tests changes.
+  However, it requires that :prop_tgt:`CROSSCOMPILING_EMULATOR` is properly set
+  in order to function in a cross-compiling environment.
+
+  Additionally, setting properties on tests is somewhat less convenient, since
+  the tests are not available at CMake time.  Additional test properties may be
+  assigned to the set of tests as a whole using the ``PROPERTIES`` option.  If
+  more fine-grained test control is needed, custom content may be provided
+  through an external CTest script using the :prop_dir:`TEST_INCLUDE_FILES`
+  directory property.  The set of discovered tests is made accessible to such a
+  script via the ``<target>_TESTS`` variable.
+
+  The options are:
+
+  ``target``
+    Specifies the Catch executable, which must be a known CMake executable
+    target.  CMake will substitute the location of the built executable when
+    running the test.
+
+  ``TEST_SPEC arg1...``
+    Specifies test cases, wildcarded test cases, tags and tag expressions to
+    pass to the Catch executable with the ``--list-test-names-only`` argument.
+
+  ``EXTRA_ARGS arg1...``
+    Any extra arguments to pass on the command line to each test case.
+
+  ``WORKING_DIRECTORY dir``
+    Specifies the directory in which to run the discovered test cases.  If this
+    option is not provided, the current binary directory is used.
+
+  ``TEST_PREFIX prefix``
+    Specifies a ``prefix`` to be prepended to the name of each discovered test
+    case.  This can be useful when the same test executable is being used in
+    multiple calls to ``catch_discover_tests()`` but with different
+    ``TEST_SPEC`` or ``EXTRA_ARGS``.
+
+  ``TEST_SUFFIX suffix``
+    Similar to ``TEST_PREFIX`` except the ``suffix`` is appended to the name of
+    every discovered test case.  Both ``TEST_PREFIX`` and ``TEST_SUFFIX`` may
+    be specified.
+
+  ``PROPERTIES name1 value1...``
+    Specifies additional properties to be set on all tests discovered by this
+    invocation of ``catch_discover_tests``.
+
+  ``TEST_LIST var``
+    Make the list of tests available in the variable ``var``, rather than the
+    default ``<target>_TESTS``.  This can be useful when the same test
+    executable is being used in multiple calls to ``catch_discover_tests()``.
+    Note that this variable is only available in CTest.

 # CI and build system integration
 
 Build Systems may refer to low-level tools, like CMake, or larger systems that run on servers, like Jenkins or TeamCity. This page will talk about both.
 
-# Continuous Integration systems
+## Continuous Integration systems
 
 Probably the most important aspect to using Catch with a build server is the use of different reporters. Catch comes bundled with three reporters that should cover the majority of build servers out there - although adding more for better integration with some is always a possibility (currently we also offer TeamCity, TAP and Automake reporters).
 
 Two of these reporters are built in (XML and JUnit) and the third (TeamCity) is included as a separate header. It's possible that the other two may be split out in the future too - as that would make the core of Catch smaller for those that don't need them.
 
-## XML Reporter
+### XML Reporter
 ```-r xml``` 
 
 The XML Reporter writes in an XML format that is specific to Catch. 
 
 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.

 The disadvantage is that this schema was designed to correspond to how JUnit works - and there is a significant mismatch with how Catch works. Additionally the format is not streamable (because opening elements hold counts of failed and passing tests as attributes) - so the whole test run must complete before it can be written.
 
 ## Other reporters
-Other reporters are not part of the single-header distribution and need to be downloaded and included separately. All reporters are stored in `include/reporters` directory in the git repository, and are named `catch_reporter_*.hpp`. For example, to use the TeamCity reporter you need to download `include/reporters/catch_reporter_teamcity.hpp` and include it after Catch itself.

 Catch is designed to "just work" as much as possible. For most people the only configuration needed is telling Catch which source file should host all the implementation code (```CATCH_CONFIG_MAIN```).
 
 Nonetheless there are still some occasions where finer control is needed. For these occasions Catch exposes a set of macros for configuring how it is built.

 	CATCH_CONFIG_RUNNER	// Designates this as implementation file
 
 Although Catch is header only it still, internally, maintains a distinction between interface headers and headers that contain implementation. Only one source file in your test project should compile the implementation headers and this is controlled through the use of one of these macros - one of these identifiers should be defined before including Catch in *exactly one implementation file in your project*.
 
-#  Prefixing Catch macros

+
+## Prefixing Catch macros
 
 	CATCH_CONFIG_PREFIX_ALL
 
 To keep test code clean and uncluttered Catch uses short macro names (e.g. ```TEST_CASE``` and ```REQUIRE```). Occasionally these may conflict with identifiers from platform headers or the system under test. In this case the above identifier can be defined. This will cause all the Catch user macros to be prefixed with ```CATCH_``` (e.g. ```CATCH_TEST_CASE``` and ```CATCH_REQUIRE```).

+By default, when Catch's stringification machinery has to stringify
+a type that does not specialize `StringMaker`, does not overload `operator<<`,
+is not an enumeration and is not a range, it uses `"{?}"`. This can be
+overriden by defining `CATCH_CONFIG_FALLBACK_STRINGIFIER` to name of a
+function that should perform the stringification instead.
+
+All types that do not provide `StringMaker` specialization or `operator<<`
+overload will be sent to this function (this includes enums and ranges).
+The provided function must return `std::string` and must accept any type,
+e.g. via overloading.
+
+_Note that if the provided function does not handle a type and this type
+requires to be stringified, the compilation will fail._
+
+
+## Default reporter
+
+Catch's default reporter can be changed by defining macro
+`CATCH_CONFIG_DEFAULT_REPORTER` to string literal naming the desired
+default reporter.

+
+### `CATCH_CONFIG_FAST_COMPILE`
 Defining this flag speeds up compilation of test files by ~20%, by making 2 changes:
 * The `-b` (`--break`) flag no longer makes Catch break into debugger in the same stack frame as the failed test, but rather in a stack frame *below*.
-* The `REQUIRE` family of macros (`REQUIRE`, `REQUIRE_FALSE` and `REQUIRE_THAT`) no longer uses local try-catch block. This disables exception translation, but should not lead to false negatives.
+* Non-exception family of macros ({`REQUIRE`,`CHECK`}{`_`,`_FALSE`, `_THAT`}, no longer use local try-catch block. This disables exception translation, but should not lead to false negatives.

-## `CATCH_CONFIG_DISABLE_MATCHERS`
+### `CATCH_CONFIG_DISABLE_MATCHERS`
 When `CATCH_CONFIG_DISABLE_MATCHERS` is defined, all mentions of Catch's Matchers are ifdef-ed away from the translation unit. Doing so will speed up compilation of that TU.
 
 _Note: If you define `CATCH_CONFIG_DISABLE_MATCHERS` in the same file as Catch's main is implemented, your test executable will fail to link if you use Matchers anywhere._
 
+### `CATCH_CONFIG_DISABLE_STRINGIFICATION`
+This toggle enables a workaround for VS 2017 bug. For details see [known limitations](limitations.md#visual-studio-2017----raw-string-literal-in-assert-fails-to-compile).
 
-# Windows header clutter
+### `CATCH_CONFIG_DISABLE`
+This toggle removes most of Catch from given file. This means that `TEST_CASE`s are not registered and assertions are turned into no-ops. Useful for keeping tests within implementation files (ie for functions with internal linkage), instead of in external files.
+
+This feature is considered experimental and might change at any point.
+
+_Inspired by Doctest's `DOCTEST_CONFIG_DISABLE`_
+
+## Windows header clutter
 
 On Windows Catch includes `windows.h`. To minimize global namespace clutter in the implementation file, it defines `NOMINMAX` and `WIN32_LEAN_AND_MEAN` before including it. You can control this behaviour via two macros:
 
     CATCH_CONFIG_NO_NOMINMAX            // Stops Catch from using NOMINMAX macro 
     CATCH_CONFIG_NO_WIN32_LEAN_AND_MEAN // Stops Catch from using WIN32_LEAN_AND_MEAN macro
 
+
+## Enabling stringification
+
+By default, Catch does not stringify some types from the standard library. This is done to avoid dragging in various standard library headers by default. However, Catch does contain these and can be configured to provide them, using these macros:
+
+    CATCH_CONFIG_ENABLE_PAIR_STRINGMAKER    // Provide StringMaker specialization for std::pair
+    CATCH_CONFIG_ENABLE_TUPLE_STRINGMAKER   // Provide StringMaker specialization for std::tuple

 # Known limitations
 
 Catch has some known limitations, that we are not planning to change. Some of these are caused by our desire to support C++98 compilers, some of these are caused by our desire to keep Catch crossplatform, some exist because their priority is seen as low compared to the development effort they would need and some other yet are compiler/runtime bugs.
 
+## Implementation limits
+### Sections nested in loops
+
+If you are using `SECTION`s inside loops, you have to create them with different name per loop's iteration. The recommended way to do so is to incorporate the loop's counter into section's name, like so
+```cpp
+TEST_CASE( "Looped section" ) {
+    for (char i = '0'; i < '5'; ++i) {
+        SECTION(std::string("Looped section ") + i) {

 ## Built in matchers
-Currently Catch has some string matchers and some vector matchers. They are in the `Catch::Matchers` and `Catch` namespaces.
-The string matchers are `StartsWith`, `EndsWith`, `Contains` and `Equals`. Each of them also takes an optional second argument, that decides case sensitivity (by-default, they are case sensitive).
+Catch currently provides some matchers, they are in the `Catch::Matchers` and `Catch` namespaces.
+
+### String matchers
+The string matchers are `StartsWith`, `EndsWith`, `Contains`, `Equals` and `Matches`. The first four match a literal (sub)string against a result, while `Matches` takes and matches an ECMAScript regex. Do note that `Matches` matches the string as a whole, meaning that "abc" will not match against "abcd", but "abc.*" will.
+
+Each of the provided `std::string` matchers also takes an optional second argument, that decides case sensitivity (by-default, they are case sensitive).
+
+
+### Vector matchers
 The vector matchers are `Contains`, `VectorContains` and `Equals`. `VectorContains` looks for a single element in the matched vector, `Contains` looks for a set (vector) of elements inside the matched vector.
 
+### Floating point matchers
+The floating point matchers are `WithinULP` and `WithinAbs`. `WithinAbs` accepts floating point numbers that are within a certain margin of target. `WithinULP` performs an [ULP](https://en.wikipedia.org/wiki/Unit_in_the_last_place)-based comparison of two floating point numbers and accepts them if they are less than certain number of ULPs apart.
+
+Do note that ULP-based checks only make sense when both compared numbers are of the same type and `WithinULP` will use type of its argument as the target type. This means that `WithinULP(1.f, 1)` will expect to compare `float`s, but `WithinULP(1., 1)` will expect to compare `double`s.
+
+
+### Generic matchers
+Catch also aims to provide a set of generic matchers. Currently this set
+contains only a matcher that takes arbitrary callable predicate and applies
+it onto the provided object.
+
+Because of type inference limitations, the argument type of the predicate
+has to be provided explicitly. Example:
+```cpp
+REQUIRE_THAT("Hello olleH",
+             Predicate<std::string>(
+                 [] (std::string const& str) -> bool { return str.front() == str.back(); },
+                 "First and last character should be equal")
+);
+```
+
+The second argument is an optional description of the predicate, and is
+used only during reporting of the result.
+

+
+## 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.

-### Improvements
+# 2.2.3
+
+**To fix some of the bugs, some behavior had to change in potentially breaking manner.**
+**This means that even though this is a patch release, it might not be a drop-in replacement.**
+
+## Fixes
+* Listeners are now called before reporter
+  * This was always documented to be the case, now it actually works that way
+* Catch's commandline will no longer accept multiple reporters
+  * This was done because multiple reporters never worked properly and broke things in non-obvious ways
+  * **This has potential to be a breaking change**
+* MinGW is now detected as Windows platform w/o SEH support (#1257)
+  * This means that Catch2 no longer tries to use POSIX signal handling when compiled with MinGW
+* Fixed potential UB in parsing tags using non-ASCII characters (#1266)
+  * Note that Catch2 still supports only ASCII test names/tags/etc
+* `TEST_CASE_METHOD` can now be used on classnames containing commas (#1245)
+  * You have to enclose the classname in extra set of parentheses
+* Fixed insufficient alt stack size for POSIX signal handling (#1225)
+* Fixed compilation error on Android due to missing `std::to_string` in C++11 mode (#1280)
+* Fixed the order of user-provided `FALLBACK_STRINGIFIER` in stringification machinery (#1024)
+  * It was intended to be replacement for built-in fallbacks, but it was used _after_ them.
+  * **This has potential to be a breaking change**
+* Fixed compilation error when a type has an `operator<<` with templated lhs (#1285, #1306)
+
+## Improvements
+* Added a new, experimental, output capture (#1243)
+  * This capture can also redirect output written via C apis, e.g. `printf`
+  * To opt-in, define `CATCH_CONFIG_EXPERIMENTAL_REDIRECT` in the implementation file
+* Added a new fallback stringifier for classes derived from `std::exception`
+  * Both `StringMaker` specialization and `operator<<` overload are given priority
+
+## Miscellaneous
+* `contrib/` now contains dbg scripts that skip over Catch's internals (#904, #1283)
+  * `gdbinit` for gdb `lldbinit` for lldb
+* `CatchAddTests.cmake` no longer strips whitespace from tests (#1265, #1281)
+* Online documentation now describes `--use-colour` option (#1263)
+
+
+# 2.2.2
+
+## Fixes
+* Fixed bug in `WithinAbs::match()` failing spuriously (#1228)
+* Fixed clang-tidy diagnostic about virtual call in destructor (#1226)
+* Reduced the number of GCC warnings suppression leaking out of the header (#1090, #1091)
+  * Only `-Wparentheses` should be leaking now
+* Added upper bound on the time benchmark timer calibration is allowed to take (#1237)
+  * On platforms where `std::chrono::high_resolution_clock`'s resolution is low, the calibration would appear stuck
+* Fixed compilation error when stringifying static arrays of `unsigned char`s (#1238)
+
+## Improvements
+* XML encoder now hex-encodes invalid UTF-8 sequences (#1207)
+  * This affects xml and junit reporters
+  * Some invalid UTF-8 parts are left as is, e.g. surrogate pairs. This is because certain extensions of UTF-8 allow them, such as WTF-8.
+* CLR objects (`T^`) can now be stringified (#1216)
+  * This affects code compiled as C++/CLI
+* Added `PredicateMatcher`, a matcher that takes an arbitrary predicate function (#1236)
+  * See [documentation for details](https://github.com/catchorg/Catch2/blob/master/docs/matchers.md)
+
+## Others
+* Modified CMake-installed pkg-config to allow `#include <catch.hpp>`(#1239)
+  * The plans to standardize on `#include <catch2/catch.hpp>` are still in effect
+
+
+# 2.2.1
+
+## Fixes
+* Fixed compilation error when compiling Catch2 with `std=c++17` against libc++ (#1214)
+  * Clara (Catch2's CLI parsing library) used `std::optional` without including it explicitly
+* Fixed Catch2 return code always being 0 (#1215)
+  * In the words of STL, "We feel superbad about letting this in"
+
+
+# 2.2.0
+
+## Fixes
+* Hidden tests are not listed by default when listing tests (#1175)
+  * This makes `catch_discover_tests` CMake script work better
+* Fixed regression that meant `<windows.h>` could potentially not be included properly (#1197)
+* Fixed installing `Catch2ConfigVersion.cmake` when Catch2 is a subproject.
+
+## Improvements
+* Added an option to warn (+ exit with error) when no tests were ran (#1158)
+  * Use as `-w NoTests`
+* Added provisional support for Emscripten (#1114)
+* [Added a way to override the fallback stringifier](https://github.com/catchorg/Catch2/blob/master/docs/configuration.md#fallback-stringifier) (#1024)
+  * This allows project's own stringification machinery to be easily reused for Catch
+* `Catch::Session::run()` now accepts `char const * const *`, allowing it to accept array of string literals (#1031, #1178)
+  * The embedded version of Clara was bumped to v1.1.3
+* Various minor performance improvements
+* Added support for DJGPP DOS crosscompiler (#1206)
+
+
+# 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
+
+## Improvements
+* Static arrays are now properly stringified like ranges across MSVC/GCC/Clang
+* Embedded newer version of Clara -- v1.1.1
+  * This should fix some warnings dragged in from Clara
+* MSVC's CLR exceptions are supported
+
+
+## Fixes
+* Fixed compilation when comparison operators do not return bool (#1147)
+* Fixed CLR exceptions blowing up the executable during translation (#1138)
+
+
+## Other changes
+* Many CMake changes
+  * `NO_SELFTEST` option is deprecated, use `BUILD_TESTING` instead.
+  * Catch specific CMake options were prefixed with `CATCH_` for namespacing purposes
+  * Other changes to simplify Catch2's packaging
+
+
+
+# 2.1.0
+
+## Improvements
+* Various performance improvements
+  * On top of the performance regression fixes
+* Experimental support for PCH was added (#1061)
+* `CATCH_CONFIG_EXTERNAL_INTERFACES` now brings in declarations of Console, Compact, XML and JUnit reporters
+* `MatcherBase` no longer has a pointless second template argument
+* Reduced the number of warning suppressions that leak into user's code
+  * Bugs in g++ 4.x and 5.x mean that some of them have to be left in
+
+
+## Fixes
+* Fixed performance regression from Catch classic
+  * One of the performance improvement patches for Catch classic was not applied to Catch2
+* Fixed platform detection for iOS (#1084)
+* Fixed compilation when `g++` is used together with `libc++` (#1110)
+* Fixed TeamCity reporter compilation with the single header version
+  * To fix the underlying issue we will be versioning reporters in single_include folder per release
+* The XML reporter will now report `WARN` messages even when not used with `-s`
+* Fixed compilation when `VectorContains` matcher was combined using `&&` (#1092)
+* Fixed test duration overflowing after 10 seconds (#1125, #1129)
+* Fixed `std::uncaught_exception` deprecation warning (#1124)
+
+
+## New features
+* New Matchers
+  * Regex matcher for strings, `Matches`.
+  * Set-equal matcher for vectors, `UnorderedEquals`
+  * Floating point matchers, `WithinAbs` and `WithinULP`.
+* Stringification now attempts to decompose all containers (#606)
+  * Containers are objects that respond to ADL `begin(T)` and `end(T)`.
+
+
+## Other changes
+* Reporters will now be versioned in the `single_include` folder to ensure their compatibility with the last released version
+
+
+
+
+# 2.0.1
+
+## Breaking changes
+* Removed C++98 support
+* Removed legacy reporter support
+* Removed legacy generator support
+  * Generator support will come back later, reworked
+* Removed `Catch::toString` support
+  * The new stringification machinery uses `Catch::StringMaker` specializations first and `operator<<` overloads second.
+* Removed legacy `SCOPED_MSG` and `SCOPED_INFO` macros
+* Removed `INTERNAL_CATCH_REGISTER_REPORTER`
+  * `CATCH_REGISTER_REPORTER` should be used to register reporters
+* Removed legacy `[hide]` tag
+  * `[.]`, `[.foo]` and `[!hide]` are still supported
+* Output into debugger is now colourized
+* `*_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
+
+
+## Improvements
+* Reporters and Listeners can be defined in files different from the main file
+  * The file has to define `CATCH_CONFIG_EXTERNAL_INTERFACES` before including catch.hpp.
+* Errors that happen during set up before main are now caught and properly reported once main is entered
+  * If you are providing your own main, you can access and use these as well.
+* New assertion macros, *_THROWS_MATCHES(expr, exception_type, matcher) are provided
+  * As the arguments suggest, these allow you to assert that an expression throws desired type of exception and pass the exception to a matcher.
+* JUnit reporter no longer has significantly different output for test cases with and without sections
+* Most assertions now support expressions containing commas (ie `REQUIRE(foo() == std::vector<int>{1, 2, 3});`)
+* Catch now contains experimental micro benchmarking support
+  * See `projects/SelfTest/Benchmark.tests.cpp` for examples
+  * The support being experiment means that it can be changed without prior notice
+* Catch uses new CLI parsing library (Clara)
+  * Users can now easily add new command line options to the final executable
+  * This also leads to some changes in `Catch::Session` interface
+* All parts of matchers can be removed from a TU by defining `CATCH_CONFIG_DISABLE_MATCHERS`
+  * This can be used to somewhat speed up compilation times
+* An experimental implementation of `CATCH_CONFIG_DISABLE` has been added
+  * Inspired by Doctest's `DOCTEST_CONFIG_DISABLE`
+  * Useful for implementing tests in source files
+    * ie for functions in anonymous namespaces
+  * Removes all assertions
+  * Prevents `TEST_CASE` registrations
+  * Exception translators are not registered
+  * Reporters are not registered
+  * Listeners are not registered
+* Reporters/Listeners are now notified of fatal errors
+  * This means specific signals or structured exceptions
+  * The Reporter/Listener interface provides default, empty, implementation to preserve backward compatibility
+* Stringification of `std::chrono::duration` and `std::chrono::time_point` is now supported
+  * Needs to be enabled by a per-file compile time configuration option
+* Add `pkg-config` support to CMake install command
+
+
+## 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
+  * SEH handling and colorized output are disabled when compiling for UWP
+* Implemented a workaround for `std::uncaught_exception` issues in libcxxrt
+  * These issues caused incorrect section traversals
+  * The workaround is only partial, user's test can still trigger the issue by using `throw;` to rethrow an exception
+* Suppressed C4061 warning under MSVC
+
+
+## Internal changes
+* The development version now uses .cpp files instead of header files containing implementation.
+  * This makes partial rebuilds much faster during development
+* The expression decomposition layer has been rewritten
+* The evaluation layer has been rewritten
+* New library (TextFlow) is used for formatting text to output
+
+
+# Older versions
+
+## 1.11.x
+
+### 1.11.0
+
+#### Fixes
+* The original expression in `REQUIRE_FALSE( expr )` is now reporter properly as `!( expr )` (#1051)
+  * Previously the parentheses were missing and `x != y` would be expanded as `!x != x`
+* `Approx::Margin` is now inclusive (#952)
+  * Previously it was meant and documented as inclusive, but the check itself wasn't
+  * This means that `REQUIRE( 0.25f == Approx( 0.0f ).margin( 0.25f ) )` passes, instead of fails
+* `RandomNumberGenerator::result_type` is now unsigned (#1050)
+
+#### Improvements
+* `__JETBRAINS_IDE__` macro handling is now CLion version specific (#1017)
+  * When CLion 2017.3 or newer is detected, `__COUNTER__` is used instead of
+* TeamCity reporter now explicitly flushes output stream after each report (#1057)
+  * On some platforms, output from redirected streams would show up only after the tests finished running
+* `ParseAndAddCatchTests` now can add test files as dependency to CMake configuration
+  * This means you do not have to manually rerun CMake configuration step to detect new tests
+
+## 1.10.x
+
+### 1.10.0
+
+#### Fixes
+* Evaluation layer has been rewritten (backported from Catch 2)
+  * The new layer is much simpler and fixes some issues (#981)
+* Implemented workaround for VS 2017 raw string literal stringification bug (#995)
+* Fixed interaction between `[!shouldfail]` and `[!mayfail]` tags and sections
+  * Previously sections with failing assertions would be marked as failed, not failed-but-ok

+* Added [libidentify](https://github.com/janwilmans/LibIdentify) support
+* Added "wait-for-keypress" option

-* `[#<filename>]` - running with `-#` or `--filenames-as-tags` causes Catch to add the filename, prefixed with `#` (and with any extension stripped) as a tag. e.g. tests in testfile.cpp would all be tagged `[#testfile]`.

+### What did we do here?
 
 Although this was a simple test it's been enough to demonstrate a few things about how Catch is used. Let's take moment to consider those before we move on.
 
-1. All we did was ```#define``` one identifier and ```#include``` one header and we got everything - even an implementation of ```main()``` that will [respond to command line arguments](command-line.md). You can only use that ```#define``` in one implementation file, for (hopefully) obvious reasons. Once you have more than one file with unit tests in you'll just ```#include "catch.hpp"``` and go. Usually it's a good idea to have a dedicated implementation file that just has ```#define CATCH_CONFIG_MAIN``` and ```#include "catch.hpp"```. You can also provide your own implementation of main and drive Catch yourself (see [Supplying-your-own-main()](own-main.md)).
-2. We introduce test cases with the ```TEST_CASE``` macro. This macro takes one or two arguments - a free form test name and, optionally, one or more tags (for more see <a href="#test-cases-and-sections">Test cases and Sections</a>, ). The test name must be unique. You can run sets of tests by specifying a wildcarded test name or a tag expression. See the [command line docs](command-line.md) for more information on running tests.

See the [command line docs](command-line.md#top) for more information on running tests.
 3. The name and tags arguments are just strings. We haven't had to declare a function or method - or explicitly register the test case anywhere. Behind the scenes a function with a generated name is defined for you, and automatically registered using static registry classes. By abstracting the function name away we can name our tests without the constraints of identifier names.
 4. We write our individual test assertions using the ```REQUIRE``` macro. Rather than a separate macro for each type of condition we express the condition naturally using C/C++ syntax. Behind the scenes a simple set of expression templates captures the left-hand-side and right-hand-side of the expression so we can display the values in our test report. As we'll see later there _are_ other assertion macros - but because of this technique the number of them is drastically reduced.
