  • Added /actual/ namespace entries, unconditional forced replacement changed to feature detection
  • Ignore return value of [@@dispose]() method when hint is async-dispose, proposal-explicit-resource-management/180
  • Added ticks for empty resources, proposal-explicit-resource-management/163
• Added some methods from Float16Array stage 3 proposal:
  • There are some reason why I don't want to add Float16Array right now, however, make sense to add some methods from this proposal.
  • Methods:
    • Math.f16round
    • DataView.prototype.getFloat16
    • DataView.prototype.setFloat16
• Added DataView get / set Uint8Clamped methods stage 1 proposal:
  • Methods:
    • DataView.prototype.getUint8Clamped
    • DataView.prototype.setUint8Clamped
• Used strict mode in some missed cases, #1269
• Fixed a Chromium 117 bug in value argument of URLSearchParams.prototype.{ has, delete }
• Fixed early WebKit ~ Safari 17.0 beta Set methods implementation by the actual spec
• Fixed incorrect Symbol.{ dispose, asyncDispose } descriptors from NodeJS 20.4 / transpilers helpers / userland code
• Fixed forced polyfilling of some iterator helpers that should return wrapped iterator in the pure version
• Fixed and exposed AsyncIteratorPrototype core-js/configurator option, #1268
• Compat data improvements:
  • Sync Iterator helpers proposal features marked as supported from V8 ~ Chrome 117
  • Array grouping proposal features marked as supported from V8 ~ Chrome 117
  • Mark Symbol.{ dispose, asyncDispose } as supported from NodeJS 20.5.0 (as mentioned above, NodeJS 20.4.0 add it, but with incorrect descriptors)
  • Added Electron 27 compat data mapping
