# Changelog ## v1.1.8 (2017-01-10) ### :bug: Bug Fix - debug: Transformations before logs. ([#128](https://github.com/babel/babel-preset-env/pull/128)) (@yavorsky) Makes sure that all transformations on `targets` (such as `exclude`/`include`) are run before logging out with the `debug` option. Fixes ([#127](https://github.com/babel/babel-preset-env/issues/127))) ### :house: Internal - remove unnecessary extension. ([#131](https://github.com/babel/babel-preset-env/pull/131)) (@roman-yakobnyuk) - Include yarn.lock and update CI. ([#124](https://github.com/babel/babel-preset-env/pull/124)) (@existentialism) ## v1.1.7 (2017-01-09) Had a publishing issue in the previous release. ## v1.1.6 (2017-01-06) ### :bug: Bug Fix - Explicitly resolve lowest browser version. ([#121](https://github.com/babel/babel-preset-env/pull/121)) (@brokenmass) ```js { "targets": { "browsers": ["ios >= 6"] // was resolving to {ios: 10} rather than {ios: 6} } } ``` ## v1.1.5 (2017-01-04) ### :bug: Bug Fix - Show error if target version is not a number. ([#107](https://github.com/babel/babel-preset-env/pull/107)) (@existentialism) ```js { "presets": [ ["env", { "targets": { "chrome": "52", // will error since it's not a number, "chrome": 52 // correct! } }] ] } ``` - Fix targets for the `debug` option. ([#109](https://github.com/babel/babel-preset-env/pull/109)) (@yavorsky) Now it prints the transformed targets/environments rather than the browsers query. ```txt Using targets: { "chrome": 53, "ie": 10, "node": 6 } Modules transform: false Using plugins: transform-es2015-arrow-functions {"chrome":47,"node":6} transform-es2015-block-scoped-functions {"chrome":41,"ie":11,"node":4} Using polyfills: es6.typed.uint8-clamped-array {"chrome":5,"node":0.12} es6.map {"chrome":51,"node":6.5} ``` ## v1.1.4 (2016-12-16) v1.1.2-v1.1.4 ### :bug: Bug Fix The new `exclude`/`include` options weren't working correctly for built-ins. ([#102](https://github.com/babel/babel-preset-env/pull/102)). Also fixes an issue with debug option. ## v1.1.1 (2016-12-13) ### :bug: Bug Fix Regression with the previous release due to using `Object.values` (ES2017). This wasn't caught because we are using babel-register to run tests and includes polyfills so it didn't fail on CI even though we have Node 0.10 as an env. Looking into fixing this to prevent future issues. ## v1.1.0 (2016-12-13) ### :rocket: New Feature - Add `exclude` option, rename `whitelist` to `include` ([#89](https://github.com/babel/babel-preset-env/pull/89)) (@hzoo) Example: ```js { "presets": [ ["env", { "targets": { "browsers": ["last 2 versions", "safari >= 7"] }, "include": ["transform-es2015-arrow-functions"], "exclude": [ "transform-regenerator", "transform-async-to-generator", "map" ], "useBuiltIns": true }] ] } ``` `"exclude": ["transform-regenerator"]` doesn't transform generators and removes `regeneratorRuntime` from being imported. `"exclude": ["transform-async-to-generator"]` doesn't use the built-in async-to-gen transform so you can use something like [fast-async](https://github.com/MatAtBread/fast-async). `"exclude": ["map"]` doesn't include the `Map` polyfill if you know you aren't using it in your code (w/ `useBuiltIns`). (We will figure out a way to automatically do this [#84](https://github.com/babel/babel-preset-env/issues/84)). If you pass a wrong plugin it will error: valid options for `include/exclude` are in [/data/plugin-features.js](https://github.com/babel/babel-preset-env/blob/master/data/plugin-features.js) and [/data/built-in-features.js](https://github.com/babel/babel-preset-env/blob/master/data/built-in-features.js) (without the `es6.`) ### :house: Internal - Optimize result filtration.

([#75](https://github.com/babel/babel-preset-env/pull/75)) (@nhajidin) ## v1.0.2 (2016-12-10) ### :bug: Bug Fix * Fix issue with Object.getOwnPropertySymbols ([#71](https://github.com/babel/babel-preset-env/pull/71)) ([@existentialism](https://github.com/existentialism)) Was requiring the wrong module kinda of like in v1.0.1: https://github.com/zloirock/core-js#ecmascript-6-symbol ```diff -import "core-js/modules/es6.object.get-own-property-symbols"; ``` The test is just a part of `Symbol`. ## v1.0.1 (2016-12-10) ### :bug: Bug Fix * Fix regenerator import ([#68](https://github.com/babel/babel-preset-env/pull/68)) ([@hzoo](https://github.com/hzoo)) We were outputting an invalid path for `regenerator`! ```diff +import "regenerator-runtime/runtime"; -import "core-js/modules/regenerator-runtime/runtime"- ``` ## v1.0.0 (2016-12-09) ### :rocket: New Feature * Add `useBuiltIns` option ([#56](https://github.com/babel/babel-preset-env/pull/56)) ([@hzoo](https://github.com/hzoo)), ([@yavorsky](https://github.com/yavorsky)), ([@existentialism](https://github.com/existentialism)) A way to apply `babel-preset-env` for polyfills (via `"babel-polyfill"``). > This option will apply a new Babel plugin that replaces `require("babel-polyfill")` with the individual requires for `babel-polyfill` based on the target environments. Install ``` npm install babel-polyfill --save ``` In ```js import "babel-polyfill"; // create an entry js file that contains this // or import "core-js"; ``` Out (different based on environment) ```js // chrome 55 import "core-js/modules/es7.string.pad-start"; // haha left_pad import "core-js/modules/es7.string.pad-end"; import "core-js/modules/web.timers"; import "core-js/modules/web.immediate"; import "core-js/modules/web.dom.iterable"; ``` `.babelrc` Usage ```js { "presets": [ ["env", { "targets": { "electron": 1.4 }, "modules": false, // webpack 2 "useBuiltIns": true // new option }] ] } ``` > Also looking to make an easier integration point via Webpack with this method. Please reach out if you have ideas! --- * Support [Electron](http://electron.atom.io/) ([#55](https://github.com/babel/babel-preset-env/pull/55)) ([@paulcbetts](https://github.com/paulcbetts)) Electron is also an environment, so [Paul went ahead](https://twitter.com/paulcbetts/status/804507070103851008) and added support for this! `.babelrc` Usage ```js { "presets": [ ["env", {"targets": { "electron": 1.4 }}]] } ``` > Currently we are manually updating the data in [/data/electron-to-chromium.js](https://github.com/babel/babel-preset-env/blob/master/data/electron-to-chromium.js), but [@kevinsawicki](https://github.com/kevinsawicki) says we could generate the data from [atom-shell/dist/index.json](https://gh-contractor-zcbenz.s3.amazonaws.com/atom-shell/dist/index.json) as well! (Someone should make a PR :smile:) ## v0.0.9 (2016-11-24) ### :rocket: New Feature * Support Opera ([#48](https://github.com/babel/babel-preset-env/pull/48)) (Henry Zhu) Was as simple as modifying the chrome version and subtracting 13! (so chrome 54 = opera 41) ```js { "presets": [ ["env", { "targets": { "opera": 41 } }] ] } ``` ## v0.0.8 (2016-11-16) ### :nail_care: Polish * Only print the debug info once ([#46](https://github.com/babel/babel-preset-env/pull/46) (Henry Zhu) When using the `debug` option it was printing the data for each file processed rather than once. ```js { "presets": [ ["env", { "debug": true }] ] } ``` ## v0.0.7 (2016-11-02) ### :rocket: New Feature * hardcode a current node version option ([#35](https://github.com/babel/babel-preset-env/pull/35)) (Henry Zhu) ```js { "presets": [ ["env", { "targets": { "node": "current" // parseFloat(process.versions.node) } }] ] } ``` * add 'whitelist' option ([#31](https://github.com/babel/babel-preset-env/pull/31)) (Henry Zhu) ```js { "presets": [ ["env", { "targets": { "chrome": 52 }, "whitelist": ["transform-es2015-arrow-functions"] }] ] } ``` * Add more aliases (Henry Zhu) * Update plugin data: firefox 52 supports async/await! ([#29](https://github.com/babel/babel-preset-env/pull/29)) (Henry Zhu) ### :bug: Bug Fixes * Use compat-table equals option ([#36](https://github.com/babel/babel-preset-env/pull/36)) (Henry Zhu) Compute and use `compat-table` equivalents ```js { "safari6": "phantom", "chrome44": "iojs", "chrome50": "node64", "chrome51": "node65", "chrome54": "node7", "chrome30": "android44", "chrome37": "android50", "chrome39": "android51", "safari7": "ios7", "safari71_8": "ios8", "safari9": "ios9", "safari10": "ios10", "chrome50": "node6" } ``` * Change default behavior to act the same as babel-preset-latest ([#33](https://github.com/babel/babel-preset-env/pull/33)) (Henry Zhu) ```js { "presets": ["env"] } // should act the same as babel-preset-latest ``` ## Internal * Add fixture helper for tests ([#28](https://github.com/babel/babel-preset-env/pull/28)) (Henry Zhu)
