# 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 `-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

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

## 1.9.x

### 1.9.6

#### Improvements
* Catch's runtime overhead has been significantly decreased (#937, #939)
* Added `--list-extra-info` cli option (#934).
  * It lists all tests together with extra information, ie filename, line number and description.



### 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



### 1.9.4

#### Fixes
* `CATCH_FAIL` macro no longer causes compilation error without variadic macro support
* `INFO` messages are no longer cleared after being reported once

#### Improvements and minor changes
* Catch now uses `wmain` when compiled under Windows and `UNICODE` is defined.
  * Note that Catch still officially supports only ASCII

### 1.9.3

#### Fixes
* Completed the fix for (lack of) uint64_t in earlier Visual Studios

### 1.9.2

#### Improvements and minor changes
* All of `Approx`'s member functions now accept strong typedefs in C++11 mode (#888)
  * Previously `Approx::scale`, `Approx::epsilon`, `Approx::margin` and `Approx::operator()` didn't.


#### Fixes
* POSIX signals are now disabled by default under QNX (#889)
  * QNX does not support current enough (2001) POSIX specification
* JUnit no longer counts exceptions as failures if given test case is marked as ok to fail.
* `Catch::Option` should now have its storage properly aligned.
* Catch no longer attempts to define `uint64_t` on windows (#862)
  * This was causing trouble when compiled under Cygwin

#### Other
* Catch is now compiled under MSVC 2017 using `std:c++latest` (C++17 mode) in CI
* We now provide cmake script that autoregisters Catch tests into ctest.
  * See `contrib` folder.


### 1.9.1

#### Fixes
* Unexpected exceptions are no longer ignored by default (#885, #887)


### 1.9.0


#### Improvements and minor changes
* Catch no longer attempts to ensure the exception type passed by user in `REQUIRE_THROWS_AS` is a constant reference.
  * It was causing trouble when `REQUIRE_THROWS_AS` was used inside templated functions
  * This actually reverts changes made in v1.7.2
* Catch's `Version` struct should no longer be double freed when multiple instances of Catch tests are loaded into single program (#858)
  * It is now a static variable in an inline function instead of being an `extern`ed struct.
* Attempt to register invalid tag or tag alias now throws instead of calling `exit()`.
  * Because this happen before entering main, it still aborts execution
  * Further improvements to this are coming
* `CATCH_CONFIG_FAST_COMPILE` now speeds-up compilation of `REQUIRE*` assertions by further ~15%.
  * The trade-off is disabling translation of unexpected exceptions into text.
* When Catch is compiled using C++11, `Approx` is now constructible with anything that can be explicitly converted to `double`.
* Captured messages are now printed on unexpected exceptions

#### Fixes:
* Clang's `-Wexit-time-destructors` should be suppressed for Catch's internals
* GCC's `-Wparentheses` is now suppressed for all TU's that include `catch.hpp`.
  * This is functionally a revert of changes made in 1.8.0, where we tried using `_Pragma` based suppression. This should have kept the suppression local to Catch's assertions, but bugs in GCC's handling of `_Pragma`s in C++ mode meant that it did not always work.
* You can now tell Catch to use C++11-based check when checking whether a type can be streamed to output.
  * This fixes cases when an unstreamable type has streamable private base (#877)
  * [Details can be found in documentation](configuration.md#catch_config_cpp11_stream_insertable_check)


#### Other notes:
* We have added VS 2017 to our CI
* Work on Catch 2 should start soon



## 1.8.x

### 1.8.2


#### Improvements and minor changes
* TAP reporter now behaves as if `-s` was always set
  * This should be more consistent with the protocol desired behaviour.
* Compact reporter now obeys `-d yes` argument (#780)
  * The format is "XXX.123 s: <section-name>" (3 decimal places are always present).
  * Before it did not report the durations at all.
* XML reporter now behaves the same way as Console reporter in regards to `INFO`
  * This means it reports `INFO` messages on success, if output on success (`-s`) is enabled.
  * Previously it only reported `INFO` messages on failure.
* `CAPTURE(expr)` now stringifies `expr` in the same way assertion macros do (#639)
* Listeners are now finally [documented](event-listeners.md#top).
  * Listeners provide a way to hook into events generated by running your tests, including start and end of run, every test case, every section and every assertion.


#### Fixes:
* Catch no longer attempts to reconstruct expression that led to a fatal error  (#810)
  * This fixes possible signal/SEH loop when processing expressions, where the signal was triggered by expression decomposition.
* Fixed (C4265) missing virtual destructor warning in Matchers (#844)
* `std::string`s are now taken by `const&` everywhere (#842).
  * Previously some places were taking them by-value.
* Catch should no longer change errno (#835).
  * This was caused by libstdc++ bug that we now work around.
* Catch now provides `FAIL_CHECK( ... )` macro (#765).
  * Same as `FAIL( ... )`, but does not abort the test.
* Functions like `fabs`, `tolower`, `memset`, `isalnum` are now used with `std::` qualification (#543).
* Clara no longer assumes first argument (binary name) is always present (#729)
  * If it is missing, empty string is used as default.
* Clara no longer reads 1 character past argument string (#830)
* Regression in Objective-C bindings (Matchers) fixed (#854)


#### Other notes:
* We have added VS 2013 and 2015 to our CI
* Catch Classic (1.x.x) now contains its own, forked, version of Clara (the argument parser).



### 1.8.1

#### Fixes

Cygwin issue with `gettimeofday` - `#define` was not early enough

### 1.8.0

#### New features/ minor changes

* Matchers have new, simpler (and documented) interface.
  * Catch provides string and vector matchers.
  * For details see [Matchers documentation](matchers.md#top).
* Changed console reporter test duration reporting format (#322)
  * Old format: `Some simple comparisons between doubles completed in 0.000123s`
  * New format: `xxx.123s: Some simple comparisons between doubles` _(There will always be exactly 3 decimal places)_
* Added opt-in leak detection under MSVC + Windows (#439)
  * Enable it by compiling Catch's main with `CATCH_CONFIG_WINDOWS_CRTDBG`
* Introduced new compile-time flag, `CATCH_CONFIG_FAST_COMPILE`, trading features for compilation speed.
  * Moves debug breaks out of tests and into implementation, speeding up test compilation time (~10% on linux).
  * _More changes are coming_
* Added [TAP (Test Anything Protocol)](https://testanything.org/) and [Automake](https://www.gnu.org/software/automake/manual/html_node/Log-files-generation-and-test-results-recording.html#Log-files-generation-and-test-results-recording) reporters.
  * These are not present in the default single-include header and need to be downloaded from GitHub separately.
  * For details see [documentation about integrating with build systems](build-systems.md#top).
*  XML reporter now reports filename as part of the `Section` and `TestCase` tags.
* `Approx` now supports an optional margin of absolute error
  * It has also received [new documentation](assertions.md#top).

#### Fixes
* Silenced C4312 ("conversion from int to 'ClassName *") warnings in the evaluate layer.
* Fixed C4512 ("assignment operator could not be generated") warnings under VS2013.
* Cygwin compatibility fixes
  * Signal handling is no longer compiled by default.
  * Usage of `gettimeofday` inside Catch should no longer cause compilation errors.
* Improved `-Wparentheses` suppression for gcc (#674)
  * When compiled with gcc 4.8 or newer, the suppression is localized to assertions only
  * Otherwise it is supressed for the whole TU
* Fixed test spec parser issue (with escapes in multiple names)

#### Other
* Various documentation fixes and improvements


## 1.7.x

### 1.7.2

#### Fixes and minor improvements
Xml:

(technically the first two are breaking changes but are also fixes and arguably break few if any people)
* C-escape control characters instead of XML encoding them (which requires XML 1.1)
* Revert XML output to XML 1.0
* Can provide stylesheet references by extending the XML reporter
* Added description and tags attributes to XML Reporter
* Tags are closed and the stream flushed more eagerly to avoid stdout interpolation


Other:
* `REQUIRE_THROWS_AS` now catches exception by `const&` and reports expected type
* In `SECTION`s the file/ line is now of the `SECTION`. not the `TEST_CASE`
* Added std:: qualification to some functions from C stdlib
* Removed use of RTTI (`dynamic_cast`) that had crept back in
* Silenced a few more warnings in different circumstances
* Travis improvements

### 1.7.1

#### Fixes:
* Fixed inconsistency in defining `NOMINMAX` and `WIN32_LEAN_AND_MEAN` inside `catch.hpp`.
* Fixed SEH-related compilation error under older MinGW compilers, by making Windows SEH handling opt-in for compilers other than MSVC.
  * For specifics, look into the [documentation](configuration.md#top).
* Fixed compilation error under MinGW caused by improper compiler detection.
* Fixed XML reporter sometimes leaving an empty output file when a test ends with signal/structured exception.
* Fixed XML reporter not reporting captured stdout/stderr.
* Fixed possible infinite recursion in Windows SEH.
* Fixed possible compilation error caused by Catch's operator overloads being ambiguous in regards to user-defined templated operators.

### 1.7.0

#### Features/ Changes:
* Catch now runs significantly faster for passing tests
  * Microbenchmark focused on Catch's overhead went from ~3.4s to ~0.7s.
  * Real world test using [JSON for Modern C++](https://github.com/nlohmann/json)'s test suite went from ~6m 25s to ~4m 14s.
* Catch can now run specific sections within test cases.
  * For now the support is only basic (no wildcards or tags), for details see the [documentation](command-line.md#top).
* Catch now supports SEH on Windows as well as signals on Linux.
  * After receiving a signal, Catch reports failing assertion and then passes the signal onto the previous handler.
* Approx can be used to compare values against strong typedefs (available in C++11 mode only).
  * Strong typedefs mean types that are explicitly convertible to double.
* CHECK macro no longer stops executing section if an exception happens.
* Certain characters (space, tab, etc) are now pretty printed.
  * This means that a `char c = ' '; REQUIRE(c == '\t');` would be printed as `' ' == '\t'`, instead of ` == 9`.

#### Fixes:
* Text formatting no longer attempts to access out-of-bounds characters under certain conditions.
* THROW family of assertions no longer trigger `-Wunused-value` on expressions containing explicit cast.
* Breaking into debugger under OS X works again and no longer required `DEBUG` to be defined.
* Compilation no longer breaks under certain compiler if a lambda is used inside assertion macro.

#### Other:
* Catch's CMakeLists now defines install command.
* Catch's CMakeLists now generates projects with warnings enabled.


## 1.6.x

### 1.6.1

#### Features/ Changes:
* Catch now supports breaking into debugger on Linux

#### Fixes:
* Generators no longer leak memory (generators are still unsupported in general)
* JUnit reporter now reports UTC timestamps, instead of "tbd"
* `CHECK_THAT` macro is now properly defined as `CATCH_CHECK_THAT` when using `CATCH_` prefixed macros

#### Other:
* Types with overloaded `&&` operator are no longer evaluated twice when used in an assertion macro.
* The use of `__COUNTER__` is supressed when Catch is parsed by CLion
  * This change is not active when compiling a binary
* Approval tests can now be run on Windows
* CMake will now warn if a file is present in the `include` folder but not is not enumerated as part of the project
* Catch now defines `NOMINMAX` and `WIN32_LEAN_AND_MEAN` before including `windows.h`
  * This can be disabled if needed, see [documentation](configuration.md#top) for details.


### 1.6.0

#### Cmake/ projects:
* Moved CMakeLists.txt to root, made it friendlier for CLion and generating XCode and VS projects, and removed the manually maintained XCode and VS projects.

#### Features/ Changes:
* Approx now supports `>=` and `<=`
* Can now use `\` to escape chars in test names on command line
* Standardize C++11 feature toggles

#### Fixes:
* Blue shell colour
* Missing argument to `CATCH_CHECK_THROWS`
* Don't encode extended ASCII in XML
* use `std::shuffle` on more compilers (fixes deprecation warning/error)
* Use `__COUNTER__` more consistently (where available)

#### Other:
* Tweaks and changes to scripts - particularly for Approval test - to make them more portable


# Even Older versions
Release notes were not maintained prior to v1.6.0, but you should be able to work them out from the Git history
