• Recent updates of the iterator helpers proposal:
  • Added a counter parameter to helpers, proposal-iterator-helpers/211
  • Don't await non-objects returned from functions passed to AsyncIterator helpers, proposal-iterator-helpers/239
  • { Iterator, AsyncIterator }.prototype.flatMap supports returning both - iterables and iterators, proposal-iterator-helpers/233
  • Early exit on broken .next in missed cases of { Iterator, AsyncIterator }.from, proposal-iterator-helpers/232

• Added Opera Android 72 compat data mapping
• Updated Electron 22 compat data mapping

3.25.5 - 2022.10.04

• Fixed regression with an error on reuse of some built-in methods from another realm, #1133

3.25.4 - 2022.10.03

• Added a workaround of a Nashorn bug with Function.prototype.{ call, apply, bind } on string methods, #1128
• Updated lists of [Serializable] and [Transferable] objects in the structuredClone polyfill. Mainly, for better error messages if polyfilling of cloning such types is impossible
• Array.prototype.{ group, groupToMap } marked as supported from V8 ~ Chromium 108
• Added Electron 22 compat data mapping

3.25.3 - 2022.09.26

• Forced polyfilling of Array.prototype.groupToMap in the pure version for returning wrapped Map instances
• Fixed existence of Array.prototype.{ findLast, findLastIndex } in /stage/4 entry
• Added Opera Android 71 compat data mapping
• Some stylistic changes

3.25.2 - 2022.09.19

• 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 - 2022.09.08

• 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 - 2022.08.25

• 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
• Added missed NodeJS 13.2 to esmodules core-js-compat / core-js-builder target
• Added Electron 21 compat data mapping
• Added Oculus Browser 23.0 compat data mapping

3.24.1 - 2022.07.30

• NodeJS is ignored in IS_BROWSER detection to avoid a false positive with jsdom, #1110
• Fixed detection of @@species support in Promise in some old engines
• { Array, %TypedArray% }.prototype.{ findLast, findLastIndex } marked as shipped in FF104
• Added iOS Safari 15.6 compat data mapping
• Fixed Opera 15 compat data mapping

3.24.0 - 2022.07.25

• Recent updates of the iterator helpers proposal, #1101:
  • .asIndexedPairs renamed to .indexed, proposal-iterator-helpers/183:
    • Iterator.prototype.asIndexedPairs -> Iterator.prototype.indexed
    • 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
  • Throw RangeError on NaN in { Iterator, AsyncIterator }.prototype.{ drop, take }, proposal-iterator-helpers/181
  • Many other updates and fixes of this proposal
• %TypedArray%.prototype.toSpliced method removed from the change array by copy proposal and marked as obsolete in core-js, proposal-change-array-by-copy/88
• Polyfill Promise with unhandledrejection event support (browser style) in Deno < 1.24
• Available new targets in core-js-compat / core-js-builder and added compat data for them:
  • Bun (bun), compat data for 0.1.1-0.1.5, #1103
  • Hermes (hermes), compat data for 0.1-0.11, #1099
  • Oculus Browser (oculus), compat data mapping for 3.0-22.0, #1098
