   - The methods renamed to end with `Symbol`, [May 2023 TC39 meeting](https://github.com/babel/proposals/issues/88#issuecomment-1548219580):
     - `Symbol.isRegistered` -> `Symbol.isRegisteredSymbol`
     - `Symbol.isWellKnown` -> `Symbol.isWellKnownSymbol`
+- Added `value` argument of `URLSearchParams.prototype.{ has, delete }`, [url/735](https://github.com/whatwg/url/pull/735)
 - Fixed some cases of increasing buffer size in `ArrayBuffer.prototype.{ transfer, transferToFixedLength }` polyfills
 - Fixed awaiting async `AsyncDisposableStack.prototype.adopt` callback, [#1258](https://github.com/zloirock/core-js/issues/1258)
 - Compat data improvements:
   - `Set.prototype.difference` that was missed in Bun because of [a bug](https://github.com/oven-sh/bun/issues/2309) added in 0.6.0
   - `Array.prototype.{ group, groupToMap }` are disabled from Bun 0.6.2 because of [web compat issues](https://github.com/tc39/proposal-array-grouping/issues/44)
+  - `value` argument of `URLSearchParams.prototype.{ has, delete }` marked as [supported](https://github.com/nodejs/node/pull/47885) from NodeJS 20.2.0
   - Added Deno 1.34 compat data mapping
   - Added Electron 26 compat data mapping
