• 3.25.2 - 2022-09-18
  • Considering document.all as a callable in some missed cases
  • Added Safari 16.0 compat data
  • Added iOS Safari 16.0 compat data mapping
  • Fixed some ancient iOS Safari versions compat data mapping
• 3.25.1 - 2022-09-07
  • Added some fixes and workarounds of FF30- typed arrays bug that does not properly convert objects to numbers
  • Added sideEffects field to core-js-pure package.json for better tree shaking, #1117
  • Dropped semver dependency from core-js-compat
    • semver package (ironically) added a breaking change and dropped NodeJS 8 support in the minor 7.1 version, after that semver in core-js-compat was pinned to 7.0 since for avoiding breaking changes it should support NodeJS 8. However, since core-js-compat is usually used with other packages that use semver dependency, it causes multiple duplications of semver in dependencies. So I decided to remove semver dependency and replace it with a couple of simple helpers.
  • Added Bun 0.1.6-0.1.11 compat data
  • Added Deno 1.25 compat data mapping
  • Updated Electron 21 compat data mapping
  • Some stylistic changes, minor fixes, and improvements
• 3.25.0 - 2022-08-24
  • Added Object.prototype.__proto__ polyfill
    • It's optional, legacy, and in some cases (mainly because of developers' mistakes) can cause problems, but some libraries depend on it, and most code can't work without the proper libraries' ecosystem
    • Only for modern engines where this feature is missed (like Deno), it's not installed in IE10- since here we have no proper way setting of the prototype
    • Without fixes of early implementations where it's not an accessor since those fixes are impossible
    • Only for the global version
  • Considering document.all as an object in some missed cases, see ECMAScript Annex B 3.6
  • Avoiding unnecessary promise creation and validation result in %WrapForValid(Async)IteratorPrototype%.return, proposal-iterator-helpers/215
  • Fixed omitting the result of proxing .return in %IteratorHelperPrototype%.return, #1116
  • Fixed the order creation of properties of iteration result object of some iterators (value should be created before done)
  • Fixed some cases of Safari < 13 bug - silent on non-writable array .length setting
  • Fixed ArrayBuffer.length in V8 ~ Chrome 27-
  • Relaxed condition of re-usage native WeakMap for internal states with multiple core-js copies
  • Availability cloning of FileList in the structuredClone polyfill extended to some more old engines versions
  • Some stylistic changes and minor fixes
  • Throwing a TypeError in core-js-compat / core-js-builder in case of passing invalid module names / filters for avoiding unexpected result, related to #1115

      • AsyncIterator.prototype.asIndexedPairs -> AsyncIterator.prototype.indexed
    • Avoid exposing spec fiction %AsyncFromSyncIteratorPrototype% in AsyncIterator.from and Iterator.prototype.toAsync, proposal-iterator-helpers/182, proposal-iterator-helpers/202
    • Avoid unnecessary promise creation in %WrapForValidAsyncIteratorPrototype%.next, proposal-iterator-helpers/197
    • Do not validate value in %WrapForValid(Async)IteratorPrototype%.next, proposal-iterator-helpers/197 and proposal-iterator-helpers/205
    • Do not forward the parameter of .next / .return to an underlying iterator by the extended iterator protocol, a part of proposal-iterator-helpers/194
    • .throw methods removed from all wrappers / helpers prototypes, a part of proposal-iterator-helpers/194
    • Close inner iterators of { Iterator, AsyncIterator }.prototype.flatMap proxy iterators on .return, proposal-iterator-helpers/195

  • Added a fix of the FF103+ structuredClone bugs (1774866 (fixed in FF104) and 1777321 (still not fixed)) that now can clone errors, but .stack of the clone is an empty string
