# 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).
  * 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)


### 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).
* 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).
*  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).

### 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` supression for gcc (#674)
  * When compiled with gcc 4.8 or newer, the supression 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


# 1.7.2

### 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 attribites 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).
* 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).
* 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.


## 1.6.1

### 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) 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


# 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
