### 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.
