# [6.0.0](v5.2.3...v6.0.0) (2021-01-13)

### Bug Fixes

* **ci:** abandon browserstack tests for Safari and IE ([#3615](#3615)) ([04a811d](04a811d))
* **client:** do not reset karmaNavigating in unload handler ([#3591](#3591)) ([4a8178f](4a8178f)), closes [#3482](#3482)
* **context:** do not error when karma is navigating ([#3565](#3565)) ([05dc288](05dc288)), closes [#3560](#3560)
* **cve:** update ua-parser-js to 0.7.23 to fix CVE-2020-7793 ([#3584](#3584)) ([f819fa8](f819fa8))
* **cve:** update yargs to 16.1.1 to fix cve-2020-7774 in y18n ([#3578](#3578)) ([3fed0bc](3fed0bc)), closes [#3577](#3577)
* **deps:** bump socket-io to v3 ([#3586](#3586)) ([1b9e1de](1b9e1de)), closes [#3569](#3569)
* **middleware:** catch errors when loading a module ([#3605](#3605)) ([fec972f](fec972f)), closes [#3572](#3572)
* **server:** clean up close-server logic ([#3607](#3607)) ([3fca456](3fca456))
* **test:** clear up clearContext ([#3597](#3597)) ([8997b74](8997b74))
* **test:** mark all second connections reconnects ([#3598](#3598)) ([1c9c2de](1c9c2de))

### Features

* **cli:** error out on unexpected options or parameters ([#3589](#3589)) ([603bbc0](603bbc0))
* **client:** update banner with connection, test status, ping times ([#3611](#3611)) ([4bf90f7](4bf90f7))
* **server:** print stack of unhandledrejections ([#3593](#3593)) ([35a5842](35a5842))
* **server:** remove deprecated static methods ([#3595](#3595)) ([1a65bf1](1a65bf1))
* remove support for running dart code in the browser ([#3592](#3592)) ([7a3bd55](7a3bd55))

### BREAKING CHANGES

* **server:** Deprecated `require('karma').server.start()` and `require('karma').Server.start()` variants were removed from the public API. Instead use canonical form:

```
const { Server } = require('karma');
const server = new Server();
server.start();
```
* **cli:** Karma is more strict and will error out if unknown option or argument is passed to CLI.
* Using Karma to run Dart code in the browser is no longer supported. Use your favorite Dart-to-JS compiler instead.

`dart` file type has been removed without a replacement.

`customFileHandlers` DI token has been removed. Use [`middleware`](http://karma-runner.github.io/5.2/config/configuration-file.html#middleware) to achieve similar functionality.

`customScriptTypes` DI token has been removed. It had no effect, so no replacement is provided.
* **deps:** Some projects have socket.io tests that are version sensitive.

The reconnecting test is flakey, sometimes running the tests twice. This is exactly
the behavior we are trying to prevent. Hard to reproduce.

Refactoring:
 * rename newBrowser to knownBrowser as appropriate.
 * move browser STATE constant set/check into browser module.
     Browser should be the only place the state is set.
 * pass singleRun and clientConfig into Browser
 * pass isSocketReconnect into browser.reconnect()
 * rename browser.onDisconnect to browser.onSocketDisconnect to distinguish
   the socket from the reload cases.
