## [2.0.0-rc.0](https://github.com/cucumber/cucumber-js/compare/v1.3.1...v2.0.0-rc.0) (2016-11-24)
### Breaking Changes
* Dropped support for Node 0.10
* CLI
* `--colors / --no-colors` has moved to `--format-options '{"colorsEnabled": "<BOOLEAN>"}'`
* `--require <DIR|FILE>`: the required files are no longer reordered to require anything in a `support` directory first
* `--snippet-interface <INTERFACE>` has moved to `--format-options '{"snippetInterface": "<INTERFACE>"}'`
* `--snippet-syntax <SYNTAX>` has moved to `--format-options '{"snippetSyntax": "<SYNTAX>"}'`
* `--tags <EXPRESSION>` now uses [cucumber-tag-expressions](https://docs.cucumber.io/tag-expressions/). It is no longer repeatable and new values will override previous
* `--tags @dev` stays the same
* `--tags ~@dev` becomes `--tags 'not @dev'`
* `--tags @foo,@bar` becomes `--tags '@foo and @bar'`
* `--tags @foo --tags @bar` becomes `--tags '@foo or bar'`
* Internals
* complete rewrite using ES2015 and promises
* JSON Formatter
* String attachments are no longer base64 encoded. Buffer and Stream attachments are still base64 encoded.
* Support Files
* Attachments
* The `attach` function used for adding attachments moved from the API scenario object to world. It is thus now available in step definitions without saving a reference to the scenario.
```js
// 1.3.0
this.After(function(scenario, callback) {
scenario.attach(new Buffer([137, 80, 78, 71]), 'image/png')
});
// 2.0.0
this.After(function() {
this.attach(new Buffer([137, 80, 78, 71]), 'image/png');
});
```
* When attaching buffers or strings, the callback argument is ignored.
* Hooks
* Hooks now receive a [ScenarioResult](/src/models/scenario_result.js) instead of the Scenario
```js
// 1.3.0
this.After(function(scenario) {});
// 2.0.0
this.After(function(scenarioResult) {});
```
* The `tags` option for hook should now be a string instead of an array and uses [cucumber-tag-expressions](https://docs.cucumber.io/tag-expressions/)
```js
// 1.3.0
this.Before({tags: ["@foo"]}, function (scenario) {})
this.Before({tags: ["@foo,@bar"]}, function (scenario) {})
this.Before({tags: ["@foo", "@bar"]}, function (scenario) {})
// 2.0.0
this.Before({tags: "@foo"}, function (scenario) {})
this.Before({tags: "@foo and @bar"}, function (scenario) {})
this.Before({tags: "@foo or @bar"}, function (scenario) {})
```
* Step Definitions
* String patterns were removed in favor [cucumber-expressions](https://docs.cucumber.io/cucumber-expressions/)
* Regular Expressions
* capture groups matching `(-?\d+)` will be automatically converted to an integer using `parseInt`
* capture groups matching `(-?\d*\.?\d+)` will be automatically converted to a float using `parseFloat`
* Generator functions are no longer automatically run with `co`. To retain the previous functionality, use [this.setDefinitionFunctionWrapper](/docs/support_files/step_definitions.md#definition-function-wrapper)
* Event Handlers
* Objects no longer have `get*` methods and instead have exposed properties
* For example: `scenario.getName()` is now just `scenario.name`
* `StepResult` duration is now in milliseconds instead of nanoseconds
### Bug Fixes
