-### CMake
-
-In general we recommend "vendoring" Catch's single-include releases inside your own repository. If you do this, the following example shows a minimal CMake project:
-```CMake
-cmake_minimum_required(VERSION 3.0)
-
-project(cmake_test)
-
-# Prepare "Catch" library for other executables
-set(CATCH_INCLUDE_DIR ${CMAKE_CURRENT_SOURCE_DIR}/catch)
-add_library(Catch INTERFACE)
-target_include_directories(Catch INTERFACE ${CATCH_INCLUDE_DIR})
-
-# Make test executable
-set(TEST_SOURCES ${CMAKE_CURRENT_SOURCE_DIR}/main.cpp)
-add_executable(tests ${TEST_SOURCES})
-target_link_libraries(tests Catch)
-```
-Note that it assumes that the path to the Catch's header is `catch/catch.hpp` from the `CMakeLists.txt` file.
-
-
-You can also use the following CMake snippet to automatically fetch the entire Catch repository from github and configure it as an external project:
-```CMake
-cmake_minimum_required(VERSION 2.8.8)
-project(catch_builder CXX)
-include(ExternalProject)
-find_package(Git REQUIRED)
-
-ExternalProject_Add(
-    catch
-    PREFIX ${CMAKE_BINARY_DIR}/catch
-    GIT_REPOSITORY https://github.com/philsquared/Catch.git
-    TIMEOUT 10
-    UPDATE_COMMAND ${GIT_EXECUTABLE} pull
-    CONFIGURE_COMMAND ""
-    BUILD_COMMAND ""
-    INSTALL_COMMAND ""
-    LOG_DOWNLOAD ON
-   )
-
-# Expose required variable (CATCH_INCLUDE_DIR) to parent scope
-ExternalProject_Get_Property(catch source_dir)
-set(CATCH_INCLUDE_DIR ${source_dir}/single_include CACHE INTERNAL "Path to include folder for Catch")
-```
-
-If you put it in, e.g., `${PROJECT_SRC_DIR}/${EXT_PROJECTS_DIR}/catch/`, you can use it in your project by adding the following to your root CMake file:
-
-```CMake
-# Includes Catch in the project:
-add_subdirectory(${EXT_PROJECTS_DIR}/catch)
-include_directories(${CATCH_INCLUDE_DIR} ${COMMON_INCLUDES})
-enable_testing(true)  # Enables unit-testing.
-```
-
-The advantage of this approach is that you can always automatically update Catch to the latest release. The disadvantage is that it means bringing in lot more than you need.
-
-
-### Automatic test registration
-We provide 2 CMake scripts that can automatically register Catch-based
-tests with CTest,
-  * `contrib/ParseAndAddCatchTests.cmake`
-  * `contrib/CatchAddTests.cmake`
-
-The first is based on parsing the test implementation files, and attempts
-to register all `TEST_CASE`s using their tags as labels. This means that
-these:
-
-```cpp
-TEST_CASE("Test1", "[unit]") {
-    int a = 1;
-    int b = 2;
-    REQUIRE(a == b);
-}
-
-TEST_CASE("Test2") {
-    int a = 1;
-    int b = 2;
-    REQUIRE(a == b);
-}
-
-TEST_CASE("Test3", "[a][b][c]") {
-    int a = 1;
-    int b = 2;
-    REQUIRE(a == b);
-}
-```
-would be registered as 3 tests, `Test1`, `Test2` and `Test3`,
-and 4 CTest labels would be created, `a`, `b`, `c` and `unit`.
-
-
-The second is based on parsing the output of a Catch binary given
-`--list-test-names-only`. This means that it deals with inactive
-(e.g. commented-out) tests better, but requires CMake 3.10 for full
-functionality.
-
 ### CodeCoverage module (GCOV, LCOV...)
 
 If you are using GCOV tool to get testing coverage of your code, and are not sure how to integrate it with CMake and Catch, there should be an external example over at https://github.com/fkromer/catch_cmake_coverage
 
+
+### pkg-config
+
+Catch2 provides a rudimentary pkg-config integration, by registering itself
+under the name `catch2`. This means that after Catch2 is installed, you
+can use `pkg-config` to get its include path: `pkg-config --cflags catch2`.
+
+### gdb and lldb scripts
+
+Catch2's `contrib` folder also contains two simple debugger scripts,
+`gdbinit` for `gdb` and `lldbinit` for `lldb`. If loaded into their
+respective debugger, these will tell it to step over Catch2's internals
+when stepping through code.

+# CMake integration
+
+Because we use CMake to build Catch2, we also provide a couple of
+integration points for our users.
+
+1) Catch2 exports a (namespaced) CMake target
+2) Catch2's repository contains CMake scripts for automatic registration
+of `TEST_CASE`s in CTest
+
+## CMake target
+
+Catch2's CMake build exports an interface target `Catch2::Catch2`. Linking
+against it will add the proper include path and all necessary capabilities
+to the resulting binary.
+
+This means that if Catch2 has been installed on the system, it should be
+enough to do:
+```cmake
+find_package(Catch2 REQUIRED)
+target_link_libraries(tests Catch2::Catch2)
+```
+
+
+This target is also provided when Catch2 is used as a subdirectory.
+Assuming that Catch2 has been cloned to `lib/Catch2`:
+```cmake
+add_subdirectory(lib/Catch2)
+target_link_libraries(tests Catch2::Catch2)
+```
+
+## Automatic test registration
+
+Catch2's repository also contains two CMake scripts that help users
+with automatically registering their `TEST_CASE`s with CTest. They
+can be found in the `contrib` folder, and are
+
+1) `Catch.cmake` (and its dependency `CatchAddTests.cmake`)
+2) `ParseAndAddCatchTests.cmake`
+
+If Catch2 has been installed in system, both of these can be used after
+doing `find_package(Catch2 REQUIRED)`. Otherwise you need to add them
+to your CMake module path.
+
+### `Catch.cmake` and `AddCatchTests.cmake`
+
+`Catch.cmake` provides function `catch_discover_tests` to get tests from
+a target. This function works by running the resulting executable with
+`--list-test-names-only` flag, and then parsing the output to find all
+existing tests. 
+
+#### Usage
+```cmake
+cmake_minimum_required(VERSION 3.5)
+
+project(baz LANGUAGES CXX VERSION 0.0.1)
+
+find_package(Catch2 REQUIRED)
+add_executable(foo test.cpp)
+target_link_libraries(foo Catch2::Catch2)
+
+include(CTest)
+include(Catch)
+catch_discover_tests(foo)
+```
+
+
+#### Customization
+`catch_discover_tests` can be given several extra argumets:
+```cmake
+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]
+)
+```
+
+* `TEST_SPEC arg1...`
+
+Specifies test cases, wildcarded test cases, tags and tag expressions to
+pass to the Catch executable alongside the `--list-test-names-only` flag.
+
+
+* `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 added 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()`, with different `TEST_SPEC` or `EXTRA_ARGS`.
+
+
+* `TEST_SUFFIX suffix`
+
+Same as `TEST_PREFIX`, except it specific the _suffix_ for the test names.
+Both `TEST_PREFIX` and `TEST_SUFFIX` can be specified at the same time.
+
+
+* `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.
+
+
+### `ParseAndAddCatchTests.cmake`
+
+`ParseAndAddCatchTests` works by parsing all implementation files
+associated with the provided target, and registering them via CTest's
+`add_test`. This approach has some limitations, such as the fact that
+commented-out tests will be registered anyway.
+
+
+#### Usage
+
+```cmake
+cmake_minimum_required(VERSION 3.5)
+
+project(baz LANGUAGES CXX VERSION 0.0.1)
+
+find_package(Catch2 REQUIRED)
+add_executable(foo test.cpp)
+target_link_libraries(foo Catch2::Catch2)
+
+include(CTest)
+include(ParseAndAddCatchTests)
+ParseAndAddCatchTests(foo)
+```
+
+
+#### Customization
+
+`ParseAndAddCatchTests` provides some customization points:
+* `PARSE_CATCH_TESTS_VERBOSE` -- When `ON`, the script prints debug
+messages. Defaults to `OFF`.
+* `PARSE_CATCH_TESTS_NO_HIDDEN_TESTS` -- When `ON`, hidden tests (tests
+tagged with any of `[!hide]`, `[.]` or `[.foo]`) will not be registered.
+Defaults to `OFF`.
+* `PARSE_CATCH_TESTS_ADD_FIXTURE_IN_TEST_NAME` -- When `ON`, adds fixture
+class name to the test name in CTest. Defaults to `ON`.
+* `PARSE_CATCH_TESTS_ADD_TARGET_IN_TEST_NAME` -- When `ON`, adds target
+name to the test name in CTest. Defaults to `ON`.
+* `PARSE_CATCH_TESTS_ADD_TO_CONFIGURE_DEPENDS` -- When `ON`, adds test
+file to `CMAKE_CONFIGURE_DEPENDS`. This means that the CMake configuration
+step will be re-ran when the test files change, letting new tests be
+automatically discovered. Defaults to `OFF`.
+
+
+## CMake project options
+
+Catch2's CMake project also provides some options for other projects
+that consume it. These are
+
+* `CATCH_BUILD_TESTING` -- When `ON`, Catch2's SelfTest project will be
+built. Defaults to `ON`. Note that Catch2 also obeys `BUILD_TESTING` CMake
+variable, so _both_ of them need to be `ON` for the SelfTest to be built,
+and either of them can be set to `OFF` to disable building SelfTest.
+* `CATCH_BUILD_EXAMPLES` -- When `ON`, Catch2's usage examples will be
+built. Defaults to `OFF`.
+* `CATCH_INSTALL_DOCS` -- When `ON`, Catch2's documentation will be
+included in the installation. Defaults to `ON`.
+* `CATCH_INSTALL_HELPERS` -- When `ON`, Catch2's contrib folder will be
+included in the installation. Defaults to `ON`.
+* `BUILD_TESTING` -- When `ON` and the project is not used as a subproject,
+Catch2's test binary will be built. Defaults to `ON`.

+[You can see an example of replacing these functions here.](
+../examples/231-Cfg-OutputStreams.cpp)
 
 
+## Fallback stringifier
+
+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.
+
+This means that defining `CATCH_CONFIG_DEFAULT_REPORTER` to `"console"`
+is equivalent with the out-of-the-box experience.
+
+
+## C++11 toggles
+
+    CATCH_CONFIG_CPP11_TO_STRING // Use `std::to_string`
+
+Because we support platforms whose standard library does not contain
+`std::to_string`, it is possible to force Catch to use a workaround
+based on `std::stringstream`. On platforms other than Android,
+the default is to use `std::to_string`. On Android, the default is to
+use the `stringstream` workaround. As always, it is possible to override
+Catch's selection, by defining either `CATCH_CONFIG_CPP11_TO_STRING` or
+`CATCH_CONFIG_NO_CPP11_TO_STRING`.

+### 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>(

+# 2.3.0
+
+**This release changes the include paths provided by our CMake and
+pkg-config integration. The proper include path for the single-header
+when using one of the above is now `<catch2/catch.hpp>`. This change
+also necessitated changes to paths inside the repository, so that the
+single-header version is now at `single_include/catch2/catch.hpp`, rather
+than `single_include/catch.hpp`.**
+
+
+
+## Fixes
+* Fixed Objective-C++ build
+* `-Wunused-variable` suppression no longer leaks from Catch's header under Clang
+* Implementation of the experimental new output capture can now be disabled (#1335)
+  * This allows building Catch2 on platforms that do not provide things like `dup` or `tmpfile`.
+* The JUnit and XML reporters will no longer skip over successful tests when running without `-s`  (#1264, #1267, #1310)
+  * See improvements for more details
+
+## Improvements
+* pkg-config and CMake integration has been rewritten
+  * If you use them, the new include path is `#include <catch2/catch.hpp>`
+  * CMake installation now also installs scripts from `contrib/`
+  * For details see the [new documentation](cmake-integration.md#top)
+* Reporters now have a new customization point, `ReporterPreferences::shouldReportAllAssertions`
+  * When this is set to `false` and the tests are run without `-s`, passing assertions are not sent to the reporter.
+  * Defaults to `false`.
+* Added `DYNAMIC_SECTION`, a section variant that constructs its name using stream
+  * This means that you can do `DYNAMIC_SECTION("For X := " << x)`.
+
+
+# 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"
+

+## Fixes
+* Hidden tests are not listed by default when listing tests (#1175)

 ## Optional steps
 
-The following steps are optional, and do not have to be performed when releasing new version of Catch. However, they *should* happen, but they can happen the next day without losing anything significant.
-
-
-### vcpkg update
-
-Catch is maintaining its own port in Microsoft's package manager [vcpkg](https://github.com/Microsoft/vcpkg). This means that when new version of Catch is released, it should be posted there as well. `updateVcpkgPackage.py` can do a lot of neccessary work for you, it creates a branch and commits neccessary changes. You should review these changes, push and open a PR against vcpkg's upstream.
-
-Note that the script assumes you have your fork of vcpkg checked out in a directory next to the directory where you have checked out Catch, like so:
-```
-GitHub
-    Catch
-    vcpkg
-```
-
+Because Catch's [vcpkg](https://github.com/Microsoft/vcpkg) port updates
+itself automagically, there are no optional steps at this time.

+## 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> {

+    };
+}

 ## 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:

 ## Writing tests
 
 Let's start with a really simple example ([code](../examples/010-TestCase.cpp)). Say you have written a function to calculate factorials and now you want to test it (let's leave aside TDD for now).
