   - `%TypedArray%.prototype.filterReject` replaces `%TypedArray%.prototype.filterOut`
 - Work with symbols made stricter: some missed before case of methods that should throw error on symbols now works as they should
 - Handling `@@toPrimitive` in some cases of `ToPrimitive` internal logic made stricter
+- Fixed work of `Request` with polyfilled `URLSearchParams`, [#965](https://github.com/zloirock/core-js/issues/965)
 - Fixed some cases of typed arrays subclassing logic
 - Fixed a minor bug related to string conversion in `RegExp#exec`
