## v7.0.0-beta.52 (2018-07-06)

Deprecating the yearly/stage presets in v7 (will remove next beta). Ran `npm deprecate` on `@babel/preset-es2015`, `@babel/preset-es2016`, `@babel/preset-es2017`, `@babel/preset-stage-0`, `@babel/preset-stage-1`, `@babel/preset-stage-2`, `@babel/preset-stage-3` only for versions `>v7.0.0-beta.52`. This means this will only break your build if you are using `^` in Babel v7 beta (which we have recommended against each release). (It is unfortunate that the default behavior of npm is to use `^` when using `npm install` though; haven't made an RFC for it yet).

Also various bugfixes, change to force the pipeline plugin to have an option.

The pipeline plugin must be configured with the `minimal` option. This is so people explicitly know the implementation that is being used, and someone will be able to implement and test out the other proposal options. After all, this proposal is in Stage 1 still and the semantics are being figured out: this is a great opportunity to specify via the config what people are using.

* Fix regression by landing [#7783](https://github.com/babel/babel/pull/7783)

## v7.0.0-beta.45 (2018-04-23)

- Drop Node 4 Support (ends 4/30).
- Make Stage 2 decorators "default" (implementation is still WIP), and require people use the `decoratorsLegacy` option for easier migration.
- Change `@babel/polyfill` to not throw an error but a warning if it is imported multiple times. Also introduce another entry point without the warning
- Change how Babel handles config files regarding a lot of cases, especially for compiling `node_modules`. Introduce `babel.config.js`
  - If you are using a monorepo an a single `.babelrc`, you will need to change to `babel.config.js` like Babel itself is doing (https://github.com/babel/babel/pull/7784)
- Add ES2018 to `@babel/preset-env`: like object rest/spread, etc.
- Lots of spec and bug fixes! Shoutout to Justin (@jridgewell) and Josh (@CodingItWrong) for all the PR work for private properties!

## v7.0.0-beta.4 (2017-10-30)

> Had a bug with peerDeps, moving changelog to beta.5

## v7.0.0-beta.3 (2017-10-15)

> Update from beta.2 -> beta.3 looks like this: https://github.com/babel/babel/pull/6488

---

> Wanted to get this release out first, but next release we should make necessary breaking changes for later: using peerDeps on babel-core so that people don't install incompatible versions of plugins/babel itself and get weird errors reported, using scoped npm packages like `@babel/core` due to issues with npm squatting, knowing what is an official package or not, etc, and renaming proposal plugins to `babel-plugin-proposal-x` instead of `babel-plugin-transform-x`

> Note: don't use `^` in your dependencies when using a beta. It can still break between (we should try not to do it but it can), so pin all the packages

- Pipeline Operator: (a |> b), also in the Stage 1 Preset
- Throw Expressions: (() => throw 'hi'), also in Stage 2
- Preset/Plugin options are available top level rather than previously only in the visitor state

## v7.0.0-alpha.20 (2017-08-30)

- Handle `Symbol` in `transform-es2015-computed-properties`
- Disallow `...[` & `...{` inside object destructuring

> http://tc39.github.io/tc39-notes/2017-05_may-23.html#16ih-why-allow-bindingpattern-for-bindingrestparameter-for-object-rest-maybe-we-should-just-allow-identifiers

```js
// Invalid
( {...{}} = {} ); ( {...[]} = {} );
let {...{}} = {}; let {...[]} = {};
```
- Split `transform-export-extensions` into `transform-export-namespace` and `transform-export-default` plugins
- Move `transform-numeric-separator` to Stage 2
- Move `transform-class-properties` to Stage 3
  - Change the default transform to use `Object.defineProperty` and `loose` option to use assignment (`this.a = 1`)
  - Use `configurable: true`
- Change `es2015-template-literals` to use `.concat` by default and concatenation in `loose` mode.
- Remove deprecated jsx pragma check in `transform-react-jsx`
- Remove `preset-flow` from the `preset-react` (there was confusion on why type syntax was allowed, and it also made it incompatible with `preset-typescript`
- Add `--config-file` CLI flag to explicitly pass a config location
- Move `babel-standalone` into the repo (another form of this used to be `babel-browser`)

## v7.0.0-alpha.16 (2017-07-25)

> Publish issue

## v7.0.0-alpha.15 (2017-07-11)

- [babel-plugin-transform-optional-chaining](https://github.com/babel/babel/tree/7.0/packages/babel-plugin-transform-optional-chaining)

> This is a Stage 0 TC39 Proposal (subject to change/removal and your feedback!)

```js
const obj = {
  foo: {
    bar: {
      baz: 42,
    },
  },
};

const baz = obj?.foo?.bar?.baz; // 42

const safe = obj?.qux?.baz; // undefined

// Optional chaining and normal chaining can be intermixed
obj?.foo.bar?.baz; // Only access `foo` if `obj` exists, and `baz` if
                   // `bar` exists
```

- [babel-plugin-transform-new-target](https://github.com/babel/babel/blob/7.0/packages/babel-plugin-transform-new-target/README.md)

```
function Foo() {
  console.log(new.target);
}

Foo(); // => undefined
new Foo(); // => Foo
```

- better `for of` optimization (if inferred array)

```js
// these kinds of scenarios will compile to a regular for loop
const x = [];
for (const y of x) {}
const arr = Object.entries(x);
for (const y of arr) {}
```
- loose mode for classes is a lot looser

Input

```js
class A {}
```

Output (loose)

```js
let A = function A() {}; // loose
```

Output (normal)

```js
function _classCallCheck(instance, Constructor) { if (!(instance instanceof Constructor)) { throw new TypeError("Cannot call a class as a function"); } }

var A = function A() {
  _classCallCheck(this, A);
};
```
