* Support for the nullish coalescing operator ([#561](https://github.com/mooz/js2-mode/pull/561)).
* Emacs 27 now provides improved JSX indentation support, along with
  new JSX highlighting and detection support. Install Emacs 27 and use
  `js-mode` with `js2-minor-mode` (see README), rather than
  `js2-jsx-mode`.
* Using `js2-jsx-mode` will now trigger a warning in Emacs 27.
* Support for optional-chaining operator `?.`

## 2019-02-19

* Changed the default of `js2-strict-trailing-comma-warning` to nil.

## 2018-03-01

* Support single-line JSDocs.
* New face `js2-object-property-access`.
* Support for trailing comma in function arguments
* JSDoc highlighting for `@yield`, `@yields`, `@abstract`, `@virtual` and `@typedef`.

* Support for ES7 public class fields.
* New user option `js2-ignored-warnings`.

## 2017-01-16

* New variable `js2-mode-assume-strict`, for use with ES6 modules.
* Support for JSDoc @callback, @func and @method tags.
* Object properties are highlighted using a different face:
  `js2-object-property`, which has no color by default.
* Experimental support for object rest/spread ECMAScript proposal.
* `js2-getter-setter-node` is renamed to `js2-method-node`, together with
  its related functions.  It already handles generator methods, and we
  added support for async methods (see below), so the old name would get
  more confusing.
* Support for default parameters in destructuring.  It should work for both
  objects and arrays, in both literals and function arguments.
* New mode: `js2-jsx-mode`, deriving from `js2-mode`.  Supports indentation of
  JSXElement expressions wrapped within parentheses or as function arguments.
  Indentation is customizable via `sgml-attribute-offset`.
* Experimental support for async/await ECMAScript proposal.

## 20150909

* `js2-mode` now derives from `js-mode`. That means the former
