    • String#{escapeHTML, unescapeHTML}
    • delay
  • Add .sham flag to features which can't be properly polyfilled and / or not recommended for usage:
    • Symbol constructor - we can't add new primitives. Object.prototype accessors too expensive.
    • Object.{create, defineProperty, defineProperties, getOwnPropertyDescriptor, getOwnPropertyDescriptos}, Reflect.{defineProperty, getOwnPropertyDescriptor} can't be properly polyfilled without descriptors support.
    • Object.{freeze, seal, preventExtensions}, Reflect.preventExtensions can't be properly polyfilled in ES3 environment.
    • Object.getPrototypeOf can be deceived in ES3 environment.
    • Reflect.construct can't be polyfilled for a correct work with newTarget argument on built-ins.
    • Typed Array constructors polyfill is quite correct but too expensive.
    • URL constructor in engines without descriptors support.
• Bug and compatibility fixes:
  • Fix deoptimisation of iterators in V8, #​377.
  • Fix import of property before constructor which should contain this property, #​262.
  • Fix some cases of IE11 WeakMap frozen keys fallback, #​384.
  • Fix non-enumerable integer keys issue because of Nashorn ~ JDK8 bug, #​389.
  • Fix Safari 12.0 Array#reverse bug.
  • One more fix for microtasks in iOS related #​339.
  • Added a fallback for Rhino bug, #​440.
  • Many other internal fixes and improvements.
• Repository:
  • Change core-js repository structure to monorepo with packages in /packages/ directory.
  • Clean-up it, remove all possible duplicates, generated files, etc.
• Packages:
  • Extract a version without global namespace pollution to a separate core-js-pure package (replacement for core-js/library).
  • Leave only one pair of bundles (global, with all polyfills) and move it to core-js-bundle package.
  • Remove bundling logic from core-js package, leave it only in core-js-builder package.
  • Clean-up packages.
  • Because of all approaches, reduce size of packages from ~2mb for core-js@2 to:
    • ~500kb for core-js package
    • ~440kb for core-js-pure package
  • Finally remove bower.json
• CommonJS API, namespaces:
  • Add availability configuration of aggressiveness.
  • Move core-js/library to separate core-js-pure package.
  • Because of removing all non-standard features, we no longer need core-js/shim entry point, replace it just with core-js.
  • Move all features from ES5, ES2015, ES2016, ES2017, ES2018 and ES2019 to one namespace for stable ES - it's available as core-js/es, all those features in modules folder has es. prefix.
  • Change prefix for ES proposals from es7. to esnext., they no longer available in core-js/es7, use core-js/stage/* instead of that.
  • Rename core-js(/library)/fn to core-js(-pure)/features for improve readability.
  • Allow more granular inclusion of features from /es/ path (for example, core-js/es/array/from).
  • Add /stable/ entry points as an equal of /features/ for stable features, without proposals.
  • Add /proposals/ entry points for allow include all features from one proposal (for example, core-js/proposals/reflect-metadata).
  • Add /es|stable|features/instance/ entry points for getting polyfill of the related method for passed instance (could be used in cases like babel-runtime).
  • Split typed arrays polyfills. Now you can, for example, load only required method (for example, core-js/es/typed-array/from).
  • Extract well-known symbols definition from es.symbol module for loading only required features, for example, in MS Edge.
  • Rename web.dom namespace to web.dom-collections.
  • Rename es6.regexp.{match, replace, search, split} -> es.string.{match, replace, search, split} - mainly it's fixes / adding support of well-known symbols to string methods, only in second place adding related methods to regexp prototype.
  • Relax /modules/ directory by moving internal modules to /internals/ directory.
  • Remove deprecated array entry points: core-js(/library)/fn/array/{pop, push, reverse, shift, unshift}.
  • core object no longer available in the global version, entry points which previously returned it now returns globalThis object. Also, don't set global core property.
  • Add some missing entry points.
• Tools, tests, code quality:
  • Added core-js-compat package with:
    • Data about the necessity of core-js modules and API for getting a list of required core-js modules by browserslist query, #​466.
    • Data which modules load by each entry point (mainly useful for tools like @babel/preset-env).
    • Data which modules added in minor versions (mainly useful for tools like @babel/preset-env).
  • core-js-builder package:
    • Added targets option with browserslist query.
    • Removed an option for generation bundle of a version without global namespace pollution - now it's an odd use case.
    • Removed UMD wrapper from a generated code of bundles - we don't need it for a global polyfill.
  • Getting rid of LiveScript, usage another language in JS standard library looks strange and impedes usage of tools like ESLint:
    • Tests are rewritten to JS.
    • Scripts are rewritten to JS.
  • Babel with minimalistic config (which should work anywhere) used on tests.
  • ESLint used on tests and tools.
  • Source code refactored for improving readability.
