### BREAKING CHANGES

* **core:** Stryker now exists with exitCode `1` if an error of any kind occurs.
* **Reporter.onScoreCalculated:** Please use the `onMutationTestReportReady` event and the `mutation-testing-metrics` npm package to calculate the mutation testing report metrics.

This
```ts
class MyReporter {
  onScoreCalculated(scoreResult) {
     // => do stuff with score result
  }
}
```

Becomes this:
```ts
import { calculateMetrics } from 'mutation-testing-metrics';
class MyReporter {
  onMutationTestingReportReady(report){
    const reportMetrics = calculateMetrics(report.files);
    // => do stuff with report metrics
  }
}
```
* **HtmlReporter:** the `html` reporter is now enabled by default. If you don't want to use it, be sure to override the `reporters` configuration option.

```json
{
  "reporters": ["progress", "clear-text"]
}
```
* **excludedMutations:** removes auto-fix for the old names of mutations.

### Migrating:
Almost every mutator has been renamed and/or split. Stryker will warn you about any deprecated mutator names in the `mutator.excludedMutations` section of your config. 

To migrate, please run stryker to see if your project is affected. If this is the case, please take a look at the mutator types on the handbook (see above).

These are the changes:  

| Old mutation           	| New mutation(s)                                       	|
|------------------------	|-------------------------------------------------------	|
| ArrayLiteral           	| ArrayDeclaration                                      	|
| ArrayNewExpression     	| ArrayDeclaration                                      	|
| BinaryExpression       	| ArithmeticOperator, EqualityOperator, LogicalOperator 	|
| Block                  	| BlockStatement                                        	|
| BooleanSubstitution    	| BooleanLiteral                                        	|
| DoStatement            	| ConditionalExpression                                 	|
| ForStatement           	| ConditionalExpression                                 	|
| IfStatement            	| ConditionalExpression                                 	|
| PrefixUnaryExpression  	| UnaryOperator, UpdateOperator, BooleanLiteral         	|
| PostfixUnaryExpression 	| UpdateOperator                                        	|
| SwitchCase             	| ConditionalExpression                                 	|
| WhileStatement         	| ConditionalExpression                                 	|


### New mutations
Due to the migration, some new mutations were added to the **javascript** mutator.
* The mutation _ArrayDeclaration_ will now mutate `new Array()` to `new Array([])`
* The mutation _ArrayDeclaration_ will now mutate `[]` to `["Stryker was here"]`

These mutations were already performed by the typescript mutator.
* **promisified fs:** removed fsAsPromised from @stryker-mutator/util

### Features

* **typescript:** Add support for TypeScript mutation testing (#376) ([ba78168](https://github.com/stryker-mutator/stryker/commit/ba78168))


### BREAKING CHANGES

* **typescript:** * Hoist the `Mutator` interface to a higher abstraction. With this interface it was possible to add mutators for specific ES5 AST nodes. As we're moving away from ES5, this plugin abstraction had to be hoisted to a higher level. It is no longer possible to plugin a specific ES5 node mutator.
* Update `report` interface: Rename `MutantState.Error` => `MutantState.RuntimeError`.
