7.1.2 (2018-09-28)

Same as v7.1.1, except compiled against Node 6 instead of Node 8 by accident (e.g had async functions).

v7.1.1 (2018-09-28)

EDIT: had a publish issue here as well where it compiled against Node 8 instead of Node 6 so 7.1.2 will fix this. Also force publish @babel/runtime and @babel/runtime-corejs2. We need to fix the publishing around that since Lerna doesn't pickup the @babel/helpers changes as there is no "dependency"

v7.0.0-beta.54 (2018-07-16)

Regarding babel#8184, we aren't using micromatch for paths, just basic */** substitution now. For anything more complicated we will recommend using a regex/.js config. Fixed a bug in the stage presets (babel#8307), so we just removed the requirements for setting options in the meantime for ease of use. We are removing the Stage presets next release. babel#8293

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.

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: babel#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

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

Publish issue

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

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

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

Foo(); // => undefined
new Foo(); // => Foo
  • better for of optimization (if inferred array)
// 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

class A {}

Output (loose)

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

Output (normal)

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);
};
