      • Symbol.dispose
      • Symbol.asyncDispose
      • SuppressedError
      • DisposableStack
        • DisposableStack.prototype.dispose
        • DisposableStack.prototype.use
        • DisposableStack.prototype.adopt
        • DisposableStack.prototype.defer
        • DisposableStack.prototype.move
        • DisposableStack.prototype[@@dispose]
      • AsyncDisposableStack
        • AsyncDisposableStack.prototype.disposeAsync
        • AsyncDisposableStack.prototype.use
        • AsyncDisposableStack.prototype.adopt
        • AsyncDisposableStack.prototype.defer
        • AsyncDisposableStack.prototype.move
        • AsyncDisposableStack.prototype[@@asyncDispose]
      • Iterator.prototype[@@dispose]
      • AsyncIterator.prototype[@@asyncDispose]
    • Moved to stable ES, May 2025 TC39 meeting
    • Added es. namespace module, /es/ and /stable/ namespaces entries
  • Array.fromAsync proposal:
    • Built-ins:
      • Array.fromAsync
    • Moved to stable ES, May 2025 TC39 meeting
    • Added es. namespace module, /es/ and /stable/ namespaces entries
  • Error.isError proposal:
    • Built-ins:
      • Error.isError
    • Moved to stable ES, May 2025 TC39 meeting
    • Added es. namespace module, /es/ and /stable/ namespaces entries
  • Added Joint iteration stage 2.7 proposal:
    • Added built-ins:
      • Iterator.zip
      • Iterator.zipKeyed
  • Added Iterator chunking stage 2 proposal:
    • Added built-ins:
      • Iterator.prototype.chunks
      • Iterator.prototype.windows
  • Number.prototype.clamp proposal:
  • Always check regular expression flags by flags getter PR. Native methods are not fixed, only own implementation updated for:
    • RegExp.prototype[@@match]
    • RegExp.prototype[@@replace]
  • Improved handling of RegExp flags in polyfills of some methods in engines without proper support of RegExp.prototype.flags and without polyfill of this getter
  • Added feature detection for a WebKit bug that occurs when this is updated while Set.prototype.difference is being executed
  • Added feature detection for a WebKit bug that occurs when iterator record of a set-like object isn't called before cloning this in the following methods:
    • Set.prototype.symmetricDifference
    • Set.prototype.union
  • Added feature detection for a bug in V8 ~ Chromium < 126. Following methods should throw an error on invalid iterator:
    • Iterator.prototype.drop
    • Iterator.prototype.filter
    • Iterator.prototype.flatMap
    • Iterator.prototype.map
  • Added feature detection for a WebKit bug: incorrect exception thrown by Iterator.from when underlying iterator's return method is null
  • Added feature detection for a FF bug: incorrect exception thrown by Array.prototype.with when index coercion fails
  • Added feature detection for a WebKit bug: TypedArray.prototype.with should truncate negative fractional index to zero, but instead throws an error
  • Worked around a bug of many different tools (example) with incorrect transforming and breaking JS syntax on getting a method from a number literal
  • Fixed deoptimization of the Promise polyfill in the pure version
  • Added some missed dependencies to /iterator/flat-map entries
  • Some other minor fixes and improvements
  • Compat data improvements:
    • Added Deno 2.3 and Deno 2.3.2 compat data mapping
    • Updated Electron 37 compat data mapping
    • Added Opera Android 90 compat data mapping
    • Error.isError marked not supported in Node because of a bug
    • Set.prototype.difference marked as not supported in Safari and supported only from Bun 1.2.5 because of a bug
    • Set.prototype.{ symmetricDifference, union } marked as not supported in Safari and supported only from Bun 1.2.5 because of a bug
    • Iterator.from marked as not supported in Safari and supported only from Bun 1.2.5 because of a bug
    • Iterators closing on early errors in Iterator helpers marked as implemented from FF141
    • Array.prototype.with marked as supported only from FF140 because it throws an incorrect exception when index coercion fails
    • TypedArray.prototype.with marked as unsupported in Bun and Safari because it should truncate negative fractional index to zero, but instead throws an error
    • DisposableStack and AsyncDisposableStack marked as shipped in FF141 (SuppressedError has a bug)
    • AsyncDisposableStack bugs marked as fixed in Deno 2.3.2
    • SuppressedError bugs (extra arguments support and arity) marked as fixed in Bun 1.2.15
