hedgehog-1.0: CHANGELOG.md

## Version 1.0 (2019-05-13)
- Add histograms to labels / coverage ([#289][289], [@jacobstanley][jacobstanley])
- Improved shrinking of lists ([#276][276], [@jacobstanley][jacobstanley] / [@edsko][edsko])
- Simplify `MonadGen`, this breaks the use of `StateT` on the outside of a `GenT` for the time being, it still works fine on the inside though and you can use `distributeT` to run it ([#276][276], [@jacobstanley][jacobstanley])
- Change `Applicative` `GenT` to use zipping ([#272][272], [@jacobstanley][jacobstanley] / [@edsko][edsko])
- Rename `Tree` -> `TreeT`, `Node` -> `NodeT` ([#272][272], [@jacobstanley][jacobstanley])
- `diff` function which takes any `a -> a -> Bool` comparison function ([#196][196], [@chessai][chessai] / [@jacobstanley][jacobstanley])
- Labelling of test runs via `label`, `collect` ([#262][262], [@ruhatch][ruhatch] / [@jacobstanley][jacobstanley])
- Classification of test runs via `cover`, `classify` ([#253][253], [@felixmulder][felixmulder] / [@jacobstanley][jacobstanley])
- Define proper `Applicative` instances for `NodeT`, `TreeT` and `GenT` ([#173][173][@sjakobi][sjakobi]

- `MonadResource` instance for `PropertyT` ([#268][268], [@geigerzaehler][geigerzaehler])
- Example for the `tripping` function ([#258][258], [@HuwCampbell][HuwCampbell])
- Improve documentation for state machine testing ([#252][252], [@endgame][endgame])
- `runTests` function for running tests from a top level executable, this was later renamed to `defaultMain` as is the de facto convention ([#168][168], [@erikd][erikd])
- Show output variables when parallel state machine testing fails to linearise ([#235][235], [@HuwCampbell][HuwCampbell])
- Note about `enumBounded` danger ([#202][202], [@thumphries][thumphries])
- Expose `discoverPrefix` to find prefixed properties ([#229][229], [@ruhatch][ruhatch])
- Remove use of `unix` package and replace with `lookupEnv` ([#226][226], [@puffnfresh][puffnfresh])

- Pass [Dieharder][Dieharder] statistical/randomness tests ([#185][185], [@moodmosaic][moodmosaic])
- Catch `readFile` exceptions on the repl ([#184][184], [@thumphries][thumphries])

## Version 0.5.3 (2018-03-12)

- Add `Semigroup` and `Monoid` instances for `GenT` that lift the inner `Monoid` ([#156][156], [@andrewthad][andrewthad])
- `Gen.unicode` no longer generates non-characters ([#154][154], [@johnchandlerburnham][johnchandlerburnham])
- Documentation improvements ([#162][162], [@fisx][fisx])
- Documentation fixes ([#157][157], [@dredozubov][dredozubov])

## Version 0.5.2 (2018-02-05)

- Add doc explaining use of `withTests 1` ([#134][134], [@chris-martin][chris-martin])
- Explicitly define `Semigroup` instance for `Summary` ([#142][142], [@gwils][gwils])

## Version 0.5.1 (2017-12-06)

- Only invoke `setNumCapabilities` when using the `-threaded` runtime ([#130][130], [@ekmett][ekmett])
- Correct `mixGamma` oddness check ([#124][124], [@markhibberd][markhibberd])

- Easier to use variables for state machine testing ([#94][94], [@jacobstanley][jacobstanley])
- `MonadGen` class allows the use of transformers like `ReaderT` and `StateT` on the outside of generators ([#99][99], [@jacobstanley][jacobstanley])
- Better error messages for tests which throw exceptions ([#95][95], [@jacobstanley][jacobstanley])
- Separated test input generation and assertions in to `PropertyT` and `TestT` respectively, this allows `TestT` to have a `MonadBaseControl` instance ([#96][96], [@jacobstanley][jacobstanley])
- This document grew links to the pull requests which introduced various changes ([#93][93], [@moodmosaic][moodmosaic])

## Version 0.4.1 (2017-06-28)

- Fixed runtime type error that could occur when shrinking state machine commands ([#91][91], [@jacobstanley][jacobstanley])

## Version 0.4 (2017-06-28)

- Abstract state machine testing, check out Tim Humphries' great [blog post](http://teh.id.au/posts/2017/07/15/state-machine-testing) or the [process registry example](https://github.com/hedgehogqa/haskell-hedgehog/blob/master/hedgehog-example/test/Test/Example/Registry.hs) to see how it works ([#89][89], [@jacobstanley][jacobstanley])

- `tripping` now displays intermediate value ([#85][85], [@jacobstanley][jacobstanley])
- `distribute` function for pulling a transformer out to the top level ([#83][83], [@jacobstanley][jacobstanley])

## Version 0.2.2 (2017-05-16)

- Fixed scope of `unicode` character generators ([#76][76], [@moodmosaic][moodmosaic])
- Widen version bounds for some dependencies ([#80][80], [@amarpotghan][amarpotghan])
- Expose test modules to fix build on nix / hydra ([#78][78], [@amarpotghan][amarpotghan])
- Fixes for GHC 8.2 RC2 ([#77][77], [@erikd][erikd])

## Version 0.2.1 (2017-05-09)

- Added `ascii`, `latin1`, `unicode` character generators ([#73][73], [@jacobstanley][jacobstanley])

## Version 0.2 (2017-05-06)

- Added a quiet test runner which can be activated by setting `HEDGEHOG_VERBOSITY=0` ([@jacobstanley][jacobstanley])
- Concurrent test runner does not display tests until they are executing ([@jacobstanley][jacobstanley])
- Test runner now outputs a summary of how many successful / failed tests were run ([@jacobstanley][jacobstanley])
- `checkSequential` and `checkParallel` now allow for tests to be run without Template Haskell ([@jacobstanley][jacobstanley])
- Auto-discovery of properties is now available via `discover` instead of being baked in ([@jacobstanley][jacobstanley])
- `annotate` allows source code to be annotated inline with extra information ([@jacobstanley][jacobstanley])
- `forAllWith` can be used to generate values without a `Show` instance ([@jacobstanley][jacobstanley])
- Removed uses of `Typeable` to allow for generating types which cannot implement it ([@jacobstanley][jacobstanley])
