v3.6.0

## Bug Fixes

- The Capabilities factory methods should only specify the name of the browser.
- Protect against the remote end sometimes not returning a list to findElements commands.
- Properly reset state in `remote.DriverService#kill()`
- The firefox module will no longer apply the preferences required by the legacy FirefoxDriver. These preferences were only required when using the legacy driver, support for which was dropped in v3.5.0.

## API Changes

- Added new methods to `selenium-webdriver/firefox.Options`:
  - addArguments()
  - headless()
  - windowSize()
- Deprecated `selenium-webdriver/firefox/binary.Binary`
- Removed `selenium-webdriver/firefox.Options#useGeckoDriver()`
- Removed the unused `selenium-webdriver/firefox/profile.decode()`
- Removed methods from `selenium-webdriver/firefox/profile.Profile` that had no effect since support for the legacy FirefoxDriver was dropped in 3.5.0:
  - setNativeEventsEnabled
  - nativeEventsEnabled
  - getPort
  - setPort
- Removed `selenium-webdriver/firefox.ServiceBuilder#setFirefoxBinary()`; custom binaries should be configured through the `firefox.Options` class.
- Removed `selenium-webdriver/firefox.Capability`. These hold overs from the legacy FirefoxDriver are no longer supported.

## Changes for W3C WebDriver Spec Compliance

- Deprecated `error.ElementNotVisibleError` in favor of the more generic `error.ElementNotInteractableError`.
- Support the `httpOnly` option when adding a cookie.

# v3.5.0

## Notice

Native support for Firefox 45 (ESR) has been removed. Users will have to connect to a remote Selenium server that supports Firefox 45.

## Changes

- Removed native support for Firefox 46 and older.
  - The `SELENIUM_MARIONETTE` enviornment variable no longer has an effect.
  - `selenium-webdriver/firefox.Capability.MARIONETTE` is deprecated.
  - `selenium-webdriver/firefox.Options#useGeckoDriver()` is deprecated and now a no-op.
- `firefox.Options` will no longer discard the `"moz:firefoxOptions"` set in user provided capabilities (via `Builder.withCapabilities({})`). When both are used, the settings in `firefox.Options` will be applied last.
- Added `chrome.Options#headless()` and `chrome.Options#windowSize()`, which may be used to start Chrome in headless mode (requires Chrome 59+) and to set the initial window size, respectively.

## Changes for W3C WebDriver Spec Compliance

- Added `error.WebDriverError#remoteStacktrace` to capture the stacktrace reported by a remote WebDriver endpoint (if any).
- Fixed `WebElement#sendKeys` to send text as a string instead of an array of strings.

# v3.4.0

## Notice

This release requires geckodriver 0.15.0 or newer.

## API Changes

- Added `Options#getTimeouts()` for retrieving the currently configured session timeouts (i.e. implicit wait). This method will only work with W3C compatible WebDriver implementations.
- Deprecated the `Timeouts` class in favor of `Options#setTimeouts()`, which supports setting multiple timeouts at once.
- Added support for emulating different network conditions (e.g., offline, 2G, WiFi) on Chrome.

## Changes for W3C WebDriver Spec Compliance

- Fixed W3C response parsing, which expects response data to always be a JSON object with a `value` key.
- Added W3C endpoints for interacting with various types of user prompts.
- Added W3C endpoints for remotely executing scripts.
- Added W3C endpoints to get current window handle and all windows handles.

# v3.3.0

- Added warning log messages when the user creates new managed promises, or schedules unchained tasks. Users may opt in to printing these log messages with

const {logging} = require('selenium-webdriver');
logging.installConsoleHandler();
logging.getLogger('promise.ControlFlow').setLevel(logging.Level.WARNING);

- If the `JAVA_HOME` environment variable is set, use it to locate java.exe.

# v3.2.0

- Release skipped to stay in sync with the main Selenium project.

# v3.1.0

- The `lib` package is once again platform agnostic (excluding `lib/devmode`).
- Deprecated `promise.when(value, callback, errback)`. Use `promise.fulfilled(value).then(callback, errback)`
- Changed `promise.fulfilled(value)`, `promise.rejected(reason)` and `promise.defer()` to all use native promises when the promise manager is disabled.
- Properly handle W3C error responses to new session commands.
- Updated `selenium-webdriver/testing` to export `describe.only` along with `describe.skip`.
- Fixed `selenium-webdriver/lib/until.ableToSwitchToFrame`. It was previously dropping arguments and would never work.
- Added the ability to use Firefox Nightly
- If Firefox cannot be found in the default location, look for it on the PATH
- Allow SafariDriver to use Safari Technology Preview.
- Use the proper wire command for WebElement.getLocation() and WebElement.getSize() for W3C compliant drivers.

# v3.0.1

- More API adjustments to align with native Promises
  - Deprecated `promise.fulfilled(value)`, use `promise.Promise#resolve(value)`
  - Deprecated `promise.rejected(reason)`, use `promise.Promise#reject(reason)`
- When a `wait()` condition times out, the returned promise will now be rejected with an `error.TimeoutError` instead of a generic `Error` object.
- `WebDriver#wait()` will now throw a TypeError if an invalid wait condition is provided.
- Properly catch unhandled promise rejections with an action sequence (only impacts when the promise manager is disabled).

# v3.0.0

- (NOTICE) The minimum supported version of Node is now 6.9.0 LTS

- Removed support for the SafariDriver browser extension. This has been replaced by Apple's safaridriver, which is included wtih Safari 10 (available on OS X El Capitan and macOS Sierra).

  To use Safari 9 or older, users will have to use an older version of Selenium.

- geckodriver v0.11.0 or newer is now required for Firefox.
- Fixed potential reference errors in `selenium-webdriver/testing` when users create a cycle with mocha by running with mocha's `--hook` flag.
- Fixed `WebDriver.switchTo().activeElement()` to use the correct HTTP method for compatibility with the W3C spec.
- Update the `selenium-webdriver/firefox` module to use geckodriver's "moz:firefoxOptions" dictionary for Firefox-specific configuration values.
- Extending the `selenium-webdriver/testing` module to support tests defined using generator functions.
- The promise manager can be disabled by setting an enviornment variable: `SELENIUM_PROMISE_MANAGER=0`. This is part of a larger plan to remove the promise manager, as documented at https://github.com/SeleniumHQ/selenium/issues/2969
- When communicating with a W3C-compliant remote end, use the atoms library for the `WebElement.getAttribute()` and `WebElement.isDisplayed()` commands. This behavior is consistent with the java, .net, python, and ruby clients.

## API Changes

- Removed `safari.Options#useLegacyDriver()`
- Reduced the API on `promise.Thenable` for compatibility with native promises:
  - Removed `#isPending()`
  - Removed `#cancel()`
  - Removed `#finally()`
- Changed all subclasses of `webdriver.WebDriver` to overload the static function `WebDriver.createSession()` instead of doing work in the constructor. All constructors now inherit the base class' function signature. Users are still encouraged to use the `Builder` class instead of creating drivers directly.
- `Builder#build()` now returns a "thenable" WebDriver instance, allowing users to immediately schedule commands (as before), or issue them through standard promise callbacks. This is the same pattern already employed for WebElements.
- Removed `Builder#buildAsync()` as it was redundant with the new semantics of `build()`.

# v3.0.0-beta-3

- Fixed a bug where the promise manager would silently drop callbacks after recovering from an unhandled promise rejection.
- Added the `firefox.ServiceBuilder` class, which may be used to customize the geckodriver used for `firefox.Driver` instances.
- Added support for Safari 10 safaridriver. safaridriver may be disabled via tha API, `safari.Options#useLegacyDriver`, to use the safari extension driver.
- Updated the `lib/proxy` module to support configuring a SOCKS proxy.
- For the `promise.ControlFlow`, fire the "uncaughtException" event in a new turn of the JS event loop. As a result of this change, any errors thrown by an event listener will propagate to the global error handler. Previously, this event was fired with in the context of a (native) promise callback, causing errors to be silently suppressed in the promise chain.

## API Changes

- Added `remote.DriverService.Builder` as a base class for configuring DriverService instances that run in a child-process. The `chrome.ServiceBuilder`, `edge.ServiceBuilder`, and `opera.ServiceBuilder` classes now all extend this base class with browser-specific options.
- For each of the ServiceBuilder clases, renamed `usingPort` and `withEnvironment` to `setPort` and `setEnvironment`, respectively.
- Renamed `chrome.ServiceBuilder#setUrlBasePath` to `#setPath`
- Changed the signature of the `firefox.Driver` from `(config, flow, executor)` to `(config, executor, flow)`.
- Exposed the `Condition` and `WebElementCondition` classes from the top-level `selenium-webdriver` module (these were previously only available from `lib/webdriver`).

## Changes for W3C WebDriver Spec Compliance

- Updated command mappings for getting and setting the window position.

# v3.0.0-beta-2

## API Changes

- Moved the `builder.Builder` class into the main module (`selenium-webdriver`).
- Removed the `builder` module.
- Fix `webdriver.WebDriver#setFileDetector` when driving Chrome or Firefox on a remote machine.

# v3.0.0-beta-1

- Allow users to set the agent used for HTTP connections through `builder.Builder#usingHttpAgent()`
- Added new wait conditions: `until.urlIs()`, `until.urlContains()`, `until.urlMatches()`
- Added work around for GeckoDriver bug raising a type conversion error
- Internal cleanup replacing uses of managed promises with native promises
- Removed the mandatory use of Firefox Dev Edition, when using Marionette driver
- Fixed timeouts' URL
- Properly send HTTP requests when using a WebDriver server proxy
- Properly configure proxies when using the geckodriver
- `http.Executor` now accepts a promised client. The `builder.Builder` class will now use this instead of a `command.DeferredExecutor` when creating WebDriver instances.
- For Chrome and Firefox, the `builder.Builder` class will always return an instanceof `chrome.Driver` and `firefox.Driver`, respectively, even when configured to use a remote server (from `builder.Builder#usingServer(url)`, `SELENIUM_REMOTE_URL`, etc).

## API Changes

- `promise.Deferred` is no longer a thenable object.
- `Options#addCookie()` now takes a record object instead of 7 individual parameters. A TypeError will be thrown if addCookie() is called with invalid arguments.
- When adding cookies, the desired expiry must be provided as a Date or in seconds since epoch. When retrieving cookies, the expiration is always returned in seconds.
- Renamed `firefox.Options#useMarionette` to `firefox.Options#useGeckoDriver`
- Removed deprecated modules:
  - `selenium-webdriver/error` (use `selenium-webdriver/lib/error`,\ or the `error` property exported by `selenium-webdriver`)
  - `selenium-webdriver/executors` — this was not previously deprecated, but is no longer used.
- Removed deprecated types:
  - `command.DeferredExecutor` — this was not previously deprecated, but is no longer used. It can be trivially implemented by clients should it be needed.
  - `error.InvalidSessionIdError` (use `error.NoSuchSessionError`)
  - `executors.DeferredExecutor`
  - `until.Condition` (use `webdriver.Condition`)
  - `until.WebElementCondition` (use `webdriver.WebElementCondition`)
  - `webdriver.UnhandledAlertError` (use `error.UnexpectedAlertOpenError`)
- Removed deprecated functions:
  - `Deferred#cancel()`
  - `Deferred#catch()`
  - `Deferred#finally()`
  - `Deferred#isPending()`
  - `Deferred#then()`
  - `Promise#thenCatch()`
  - `Promise#thenFinally()`
  - `WebDriver#isElementPresent()`
  - `WebElement#getInnerHtml()`
  - `WebElement#getOuterHtml()`
  - `WebElement#getRawId()`
  - `WebElement#isElementPresent()`
- Removed deprecated properties:
  - `WebDriverError#code`

# v2.53.2

- Changed `io.exists()` to return a rejected promise if the input path is not a string
- Deprecated `Promise#thenFinally()` - use `Promise#finally()`. The thenFinally shim added to the promise module in v2.53.0 will be removed in v3.0 Sorry for the churn!
- FIXED: capabilities serialization now properly handles undefined vs. false-like values.
- FIXED: properly handle responses from the remote end in `WebDriver.attachToSession`

# v2.53.1

- FIXED: for consistency with the other language bindings, `remote.FileDetector` will ignore paths that refer to a directory.

# v2.53.0

## Change Summary

- Added preliminary support for Marionette, Mozilla's WebDriver implementation for Firefox. Marionette may be enabled via the API, `firefox.Options#useMarionette`, or by setting the `SELENIUM_MARIONETTE` environment variable.
- Moved all logic for parsing and interpreting responses from the remote end into the individual `command.Executor` implementations.

- For consistency with the other Selenium language bindings, `WebDriver#isElementPresent()` and `WebElement#isElementPresent()` have been deprecated. These methods will be removed in v3.0. Use the findElements command to test for the presence of an element:

  driver.findElements(By.css('.foo')).then(found => !!found.length);

- Added support for W3C-spec compliant servers.
- For consistent naming, deprecating `error.InvalidSessionIdError` in favor of `error.NoSuchSessionError`.
- Moved the `error` module to `lib/error` so all core modules are co-located. The top-level `error` module will be removed in v3.0.
- Moved `until.Condition` and `until.WebElementCondition` to the webdriver module to break a circular dependency.
- Added support for setting the username and password in basic auth pop-up dialogs (currently IE only).
- Deprecated `WebElement#getInnerHtml()` and `WebEleemnt#getOuterHtml()`
- Deprecated `Promise#thenCatch()` - use `Promise#catch()` instead
- Deprecated `Promise#thenFinally()` - use `promise.thenFinally()` instead
- FIXED: `io.findInPath()` will no longer match against directories that have the same basename as the target file.
- FIXED: `phantomjs.Driver` now takes a third argument that defines the path to a log file to use for the phantomjs executable's output. This may be quickly set at runtime with the `SELENIUM_PHANTOMJS_LOG` environment variable.

## Changes for W3C WebDriver Spec Compliance

- Changed `element.sendKeys(...)` to send the key sequence as an array where each element defines a single key. The legacy wire protocol permits arrays where each element is a string of arbitrary length. This change is solely at the protocol level and should have no user-visible effect.

# v2.52.0

## Notice

Starting with v2.52.0, each release of selenium-webdriver will support the latest minor LTS and stable Node releases. All releases between the LTS and stable release will have best effort support. Further details are available in the selenium-webdriver package README.

## Change Summary

- Add support for Microsoft's Edge web browser
- Added `webdriver.Builder#buildAsync()`, which returns a promise that will be fulfilled with the newly created WebDriver instance once the associated browser has been full initialized. This is purely a convenient alternative to the existing build() method as the WebDriver class will always defer commands until it has a fully created browser.
- Added `firefox.Profile#setHost()` which may be used to set the host that the FirefoxDriver's server listens for commands on. The server uses "localhost" by default.
- Added `promise.Promise#catch()` for API compatibility with native Promises. `promise.Promise#thenCatch()` is not yet deprecated, but it simply delegates to `catch`.
- Changed some `io` operations to use native promises.
- Changed `command.Executor#execute()` and `HttpClient#send()` to return promises instead of using callback passing.
- Replaced the `Serializable` class with an internal, Symbol-defined method.
- Changed the `Capabilities` class to extend the native `Map` type.
- Changed the `Capabilities.has(key)` to only test if a capability has been set (Map semantics). To check whether the value is true, use `get(key)`.
- Deprecated `executors.DeferredExecutor` in favor of `lib/command.DeferredExecutor`.
- API documentation is no longer distributed with the npm package, but remains available at http://seleniumhq.github.io/selenium/docs/api/javascript/
- Rewrote the `error` module to export an Error subtype for each type of error defined in the W3C WebDriver spec.
- Changed the `http.Request` and `http.Response` classes to store headers in maps instead of object literals.
- Updated `ws` dependency to version `1.0.1`.
- Removed fluent predicates "is" and "not" from the experimental `testing/assert` module.
- Wait conditions that locate an element, or that wait on an element's state, will return a WebElementPromise.
- Lots of internal clean-up to break selenium-webdriver's long standing dependency on Google's Closure library.

## Changes for W3C WebDriver Spec Compliance

- Updated the `By` locators that are not in the W3C spec to delegated to using CSS selectors: `By.className`, `By.id`, `By.name`, and `By.tagName`.

# v2.49-51

- Releases skipped to stay in sync with the rest of the Selenium project

# v2.48.2

- Added `WebElement#takeScreenshot()`.
- More adjustments to promise callback tracking.

# v2.48.1

- FIXED: Adjusted how the control flow tracks promise callbacks to avoid a potential deadlock.

# v2.48.0

- Node v0.12.x users must run with –harmony. This is the last release that will support v0.12.x
- FIXED: (Promise/A+ compliance) When a promise is rejected with a thenable, the promise adopts the thenable as its rejection reason instead of waiting for it to settle. The previous (incorrect) behavior was hidden by bugs in the `promises-aplus-tests` compliance test suite that were fixed in version `2.1.1`.
- FIXED: the `webdriver.promise.ControlFlow` now has a consistent execution order for tasks/callbacks scheduled in different turns of the JS event loop. Refer to the `webdriver.promise` documentation for more details.
- FIXED: do not drop user auth from the WebDriver server URL.

- FIXED: a single `firefox.Binary` instance may be used to configure and launch multiple FirefoxDriver sessions.

  var binary = new firefox.Binary(); var options = new firefox.Options().setBinary(binary); var builder = new Builder().setFirefoxOptions(options);

  var driver1 = builder.build(); var driver2 = builder.build();

- FIXED: zip files created for transfer to a remote WebDriver server are no longer compressed. If the zip contained a file that was already compressed, the server would return an "invalid code lengths set" error.
- FIXED: Surfaced the `loopback` option to `remote/SeleniumServer`. When set, the server will be accessed using the current host's loopback address.

# v2.47.0

## Notice

This is the last release for `selenium-webdriver` that will support ES5. Subsequent releases will depend on ES6 features that are enabled by default in Node v4.0.0. Node v0.12.x will continue to be supported, but will require setting the `--harmony` flag.

## Change Summary

- Add support for Node v4.0.0
  - Updated `ws` dependency from `0.7.1` to `0.8.0`
- Bumped the minimum supported version of Node from `0.10.x` to `0.12.x`. This is in accordance with the Node support policy established in `v2.45.0`.

# v2.46.1

- Fixed internal module loading on Windows.
- Fixed error message format on timeouts for `until.elementLocated()` and `until.elementsLocated()`.

# v2.46.0

- Exposed a new logging API via the `webdriver.logging` module. For usage, see `example/logging.js`.
- Added support for using a proxy server for WebDriver commands. See `Builder#usingWebDriverProxy()` for more info.
- Removed deprecated functions:
  - Capabilities::toJSON()
  - UnhandledAlertError::getAlert()
  - chrome.createDriver()
  - phantomjs.createDriver()
  - promise.ControlFlow::annotateError()
  - promise.ControlFlow::await()
  - promise.ControlFlow::clearHistory()
  - promise.ControlFlow::getHistory()
- Removed deprecated enum values: `ErrorCode.NO_MODAL_DIALOG_OPEN` and `ErrorCode.MODAL_DIALOG_OPENED`. Use `ErrorCode.NO_SUCH_ALERT` and `ErrorCode.UNEXPECTED_ALERT_OPEN`, respectively.
- FIXED: The `promise.ControlFlow` will maintain state for promise chains generated in a loop.
- FIXED: Correct serialize target elements used in an action sequence.
- FIXED: `promise.ControlFlow#wait()` now has consistent semantics for an omitted or 0-timeout: it will wait indefinitely.
- FIXED: `remote.DriverService#start()` will now fail if the child process dies while waiting for the server to start accepting requests. Previously, start would continue to poll the server address until the timeout expired.
- FIXED: Skip launching Firefox with the `-silent` flag to preheat the profile. Starting with Firefox 38, this would cause the browser to crash. This step, which was first introduced for Selenium's java client back with Firefox 2, no longer appears to be required.
- FIXED: 8564: `firefox.Driver#quit()` will wait for the Firefox process to terminate before deleting the temporary webdriver profile. This eliminates a race condition where Firefox would write profile data during shutdown, causing the `rm -rf` operation on the profile directory to fail.

# v2.45.1

- FIXED: 8548: Task callbacks are once again dropped if the task was cancelled due to a previously uncaught error within the frame.
- FIXED: 8496: Extended the `chrome.Options` API to cover all configuration options (e.g. mobile emulation and performance logging) documented on the ChromeDriver project site.

# v2.45.0

## Important Policy Change

Starting with the 2.45.0 release, selenium-webdriver will support the last two stable minor releases for Node. For 2.45.0, this means Selenium will support Node 0.10.x and 0.12.x. Support for the intermediate, un-stable release (0.11.x) is "best-effort". This policy will be re-evaluated once Node has a major version release (i.e. 1.0.0).

## Change Summary

- Added native browser support for Internet Explorer, Opera 26+, and Safari
- With the release of Node 0.12.0 (finally!), the minimum supported version of Node is now `0.10.x`.
- The `promise` module is now Promises/A+ compliant. The biggest compliance change is that promise callbacks are now invoked in a future turn of the JS event loop. For example:

      var promise = require('selenium-webdriver').promise;
      console.log('start');
      promise.fulfilled().then(function() {
        console.log('middle');
      });
      console.log('end');

      // Output in selenium-webdriver@2.44.0
      // start
      // middle
      // end
      //
      // Output in selenium-webdriver@2.45.0
      // start
      // end
      // middle

  The `promise.ControlFlow` class has been updated to track the asynchronous breaks required by Promises/A+, so there are no changes to task execution order.
- Updated how errors are annotated on failures. When a task fails, the stacktrace from when that task was scheduled is appended to the rejection reason with a `From:` prefix (if it is an Error object). For example:

      var driver = new webdriver.Builder().forBrowser('chrome').build();
      driver.get('http://www.google.com/ncr');
      driver.call(function() {
        driver.wait(function() {
          return driver.isElementPresent(webdriver.By.id('not-there'));
        }, 2000, 'element not found');
      });

  This code will fail an error like:

      Error: element not found
      Wait timed out after 2002ms
          at <stack trace>
      From: Task: element not found
          at <stack trace>
      From: Task: WebDriver.call(function)
          at <stack trace>

- Changed the format of strings returned by `promise.ControlFlow#getSchedule`. This function now accepts a boolean to control whether the returned string should include the stacktraces for when each task was scheduled.
- Deprecating `promise.ControlFlow#getHistory`, `promise.ControlFlow#clearHistory`, and `promise.ControlFlow#annotateError`. These functions were all intended for internal use and are no longer necessary, so they have been made no-ops.
- `WebDriver.wait()` may now be used to wait for a promise to resolve, with an optional timeout. Refer to the API documentation for more information.
- Added support for copying files to a remote Selenium via `sendKeys` to test file uploads. Refer to the API documentation for more information. Sample usage included in `test/upload_test.js`
- Expanded the interactions API to include touch actions. See `WebDriver.touchActions()`.
- FIXED: 8380: `firefox.Driver` will delete its temporary profile on `quit`.
- FIXED: 8306: Stack overflow in promise callbacks eliminated.
- FIXED: 8221: Added support for defining custom command mappings. Includes support for PhantomJS's `executePhantomJS` (requires PhantomJS 1.9.7 or GhostDriver 1.1.0).
- FIXED: 8128: When the FirefoxDriver marshals an object to the page for `executeScript`, it defines additional properties (required by the driver's implementation). These properties will no longer be enumerable and should be omitted (i.e. they won't show up in JSON.stringify output).
- FIXED: 8094: The control flow will no longer deadlock when a task returns a promise that depends on the completion of sub-tasks.

# v2.44.0

- Added the `until` module, which defines common explicit wait conditions. Sample usage:

      var firefox = require('selenium-webdriver/firefox'),
          until = require('selenium-webdriver/until');

      var driver = new firefox.Driver();
      driver.get('http://www.google.com/ncr');
      driver.wait(until.titleIs('Google Search'), 1000);

- FIXED: 8000: `Builder.forBrowser()` now accepts an empty string since some WebDriver implementations ignore the value. A value must still be specified, however, since it is a required field in WebDriver's wire protocol.
- FIXED: 7994: The `stacktrace` module will not modify stack traces if the initial parse fails (e.g. the user defined `Error.prepareStackTrace`)
- FIXED: 5855: Added a module (`until`) that defines several common conditions for use with explicit waits. See updated examples for usage.

# v2.43.5

- FIXED: 7905: `Builder.usingServer(url)` once again returns `this` for chaining.

# v2.43.2-4

- No changes; version bumps while attempting to work around an issue with publishing to npm (a version string may only be used once).

# v2.43.1

- Fixed an issue with flakiness when setting up the Firefox profile that could prevent the driver from initializing properly.

# v2.43.0

- Added native support for Firefox - the Java Selenium server is no longer required.
- Added support for generator functions to `ControlFlow#execute` and `ControlFlow#wait`. For more information, see documentation on `webdriver.promise.consume`. Requires harmony support (run with `node --harmony-generators` in `v0.11.x`).
- Various improvements to the `Builder` API. Notably, the `build()` function will no longer default to attempting to use a server at `http://localhost:4444/wd/hub` if it cannot start a browser directly - you must specify the WebDriver server with `usingServer(url)`. You can also set the target browser and WebDriver server through a pair of environment variables. See the documentation on the `Builder` constructor for more information.
- For consistency with the other language bindings, added browser specific classes that can be used to start a browser without the builder.

      var webdriver = require('selenium-webdriver')
          chrome = require('selenium-webdriver/chrome');

      // The following are equivalent.
      var driver1 = new webdriver.Builder().forBrowser('chrome').build();
      var driver2 = new chrome.Driver();

- Promise A+ compliance: a promise may no longer resolve to itself.
- For consistency with other language bindings, deprecated `UnhandledAlertError#getAlert` and added `#getAlertText`. `getAlert` will be removed in `2.45.0`.
- FIXED: 7641: Deprecated `ErrorCode.NO_MODAL_DIALOG_OPEN` and `ErrorCode.MODAL_DIALOG_OPENED` in favor of the new `ErrorCode.NO_SUCH_ALERT` and `ErrorCode.UNEXPECTED_ALERT_OPEN`, respectively.
- FIXED: 7563: Mocha integration no longer disables timeouts. Default Mocha timeouts apply (2000 ms) and may be changed using `this.timeout(ms)`.
- FIXED: 7470: Make it easier to create WebDriver instances in custom flows for parallel execution.

# v2.42.1

- FIXED: 7465: Fixed `net.getLoopbackAddress` on Windows
- FIXED: 7277: Support `done` callback in Mocha's BDD interface
- FIXED: 7156: `Promise#thenFinally` should not suppress original error

# v2.42.0

- Removed deprecated functions `Promise#addCallback()`, `Promise#addCallbacks()`, `Promise#addErrback()`, and `Promise#addBoth()`.
- Fail with a more descriptive error if the server returns a malformed redirect
- FIXED: 7300: Connect to ChromeDriver using the loopback address since ChromeDriver 2.10.267517 binds to localhost by default.
- FIXED: 7339: Preserve wrapped test function's string representation for Mocha's BDD interface.

# v2.41.0

- FIXED: 7138: export logging API from webdriver module.
- FIXED: 7105: beforeEach/it/afterEach properly bind `this` for Mocha tests.

# v2.40.0

- API documentation is now included in the docs directory.
- Added utility functions for working with an array of promises: `promise.all`, `promise.map`, and `promise.filter`
- Introduced `Promise#thenCatch()` and `Promise#thenFinally()`.
- Deprecated `Promise#addCallback()`, `Promise#addCallbacks()`, `Promise#addErrback()`, and `Promise#addBoth()`.
- Removed deprecated function `webdriver.WebDriver#getCapability`.
- FIXED: 6826: Added support for custom locators.

# v2.39.0

- Version bump to stay in sync with the Selenium project.

# v2.38.1

- FIXED: 6686: Changed `webdriver.promise.Deferred#cancel()` to silently no-op if the deferred has already been resolved.

# v2.38.0

- When a promise is rejected, always annotate the stacktrace with the parent flow state so users can identify the source of an error.
- Updated tests to reflect features not working correctly in the SafariDriver (cookie management and proxy support; see issues 5051, 5212, and 5503)
- FIXED: 6284: For mouse moves, correctly omit the x/y offsets if not specified as a function argument (instead of passing (0,0)).
- FIXED: 6471: Updated documentation on `webdriver.WebElement#getAttribute`
- FIXED: 6612: On Unix, use the default IANA ephemeral port range if unable to retrieve the current system's port range.
- FIXED: 6617: Avoid triggering the node debugger when initializing the stacktrace module.
- FIXED: 6627: Safely rebuild chrome.Options from a partial JSON spec.

# v2.37.0

- FIXED: 6346: The remote.SeleniumServer class now accepts JVM arguments using the `jvmArgs` option.

# v2.36.0

- Release skipped to stay in sync with main Selenium project.

# v2.35.2

- FIXED: 6200: Pass arguments to the Selenium server instead of to the JVM.

# v2.35.1

- FIXED: 6090: Changed example scripts to use chromedriver.

# v2.35.0

- Version bump to stay in sync with the Selenium project.

# v2.34.1

- FIXED: 6079: The parent process should not wait for spawn driver service processes (chromedriver, phantomjs, etc.)

# v2.34.0

- Added the `selenium-webdriver/testing/assert` module. This module simplifies writing assertions against promised values (see example in module documentation).
- Added the `webdriver.Capabilities` class.
- Added native support for the ChromeDriver. When using the `Builder`, requesting chrome without specifying a remote server URL will default to the native ChromeDriver implementation. The ChromeDriver server must be downloaded separately.

      // Will start ChromeDriver locally.
      var driver = new webdriver.Builder().
          withCapabilities(webdriver.Capabilities.chrome()).
          build();

      // Will start ChromeDriver using the remote server.
      var driver = new webdriver.Builder().
          withCapabilities(webdriver.Capabilities.chrome()).
          usingServer('http://server:1234/wd/hub').
          build();

- Added support for configuring proxies through the builder. For examples, see `selenium-webdriver/test/proxy_test`.
- Added native support for PhantomJS.
- Changed signature of `SeleniumServer` to `SeleniumServer(jar, options)`.
- Tests are now included in the npm published package. See `README.md` for execution instructions
- Removed the deprecated `webdriver.Deferred#resolve` and `webdriver.promise.resolved` functions.
- Removed the ability to connect to an existing session from the Builder. This feature is intended for use with the browser-based client.

# v2.33.0

- Added support for WebDriver's logging API
- FIXED: 5511: Added webdriver.manage().timeouts().pageLoadTimeout(ms)

# v2.32.1

- FIXED: 5541: Added missing return statement for windows in `portprober.findFreePort()`

# v2.32.0

- Added the `selenium-webdriver/testing` package, which provides a basic framework for writing tests using Mocha. See `selenium-webdriver/example/google_search_test.js` for usage.
- For Promises/A+ compatibility, backing out the change in 2.30.0 that ensured rejections were always Error objects. Rejection reasons are now left as is.
- Removed deprecated functions originally scheduled for removal in 2.31.0
  - promise.Application.getInstance()
  - promise.ControlFlow::schedule()
  - promise.ControlFlow::scheduleTimeout()
  - promise.ControlFlow::scheduleWait()
- Renamed some functions for consistency with Promises/A+ terminology. The original functions have been deprecated and will be removed in 2.34.0:
  - promise.resolved() -> promise.fulfilled()
  - promise.Deferred::resolve() -> promise.Deferred::fulfill()
- FIXED: remote.SeleniumServer::stop now shuts down within the active control flow, allowing scripts to finish. Use #kill to shutdown immediately.
- FIXED: 5321: cookie deletion commands

# v2.31.0

- Added an example script.
- Added a class for controlling the standalone Selenium server (server available separately)
- Added a portprober for finding free ports
- FIXED: WebElements now belong to the same flow as their parent driver.

# v2.30.0

- Ensures promise rejections are always Error values.
- Version bump to keep in sync with the Selenium project.

# v2.29.1

- Added a README.md

# v2.29.0
