* **peer:** The peer dependency on `prettier` has been tightened to encompass React Hooks-related features and bugfixes, as well as to explicitly disclaim support for _all_ versions 2.x and above.
* **mocha:** Passing an arrow function to a Mocha test case is now an error.
* **style:** Prefer object spread instead of `Object.assign()`. This rule is fixable.
* **style:** Function names must match the name of the variable or property to which they are assigned.
* **style:** `camelcase` no longer errors when (predominantly) Python APIs insist on returning JSON with `snake_case` keys.
* **errors:** Assignments that can lead to race conditions due to usage of `await` or `yield` are not allowed.
* **errors:** Misleading character classes in regular expressions are not allowed.
* **errors:** Passing an `async` function to the `Promise` constructor is not allowed.
* **peer:** Several new rules require a higher minimum version of various peer plugins.
* **best-practices:** Self-assigning properties is not allowed.
* **best-practices:** Only one class per-file is allowed.
* **jest:** Emtpy test cases are no longer allowed. This rule is fixable.
* **jest:** The `toBeTruthy()` and `toBeFalsy()` assertions are no longer allowed. There are several assertions available with greater clarity.

* **jest:** Jasmine globals are no longer allowed. This rule is fixable.
* **jest:** Test cases without a call to `expect()` will now error. If you use a different assertion function, you will need to extend the [assertionFunctionNames](https://github.com/jest-community/eslint-plugin-jest/blob/master/docs/rules/expect-expect.md#assertfunctionnames) rule option.
* **best-practices:** Empty `catch` statements are not allowed.
