 - ES2020 added string method [`matchAll`](https://github.com/tc39/proposal-string-matchall) (which returns an iterator), plus `RegExp.prototype[Symbol.matchAll]`.
 - ES2021 added string method [`replaceAll`](https://github.com/tc39/proposal-string-replaceall). When given a regex, the only difference from ES3's `replace` is that it throws if not using flag `g`.
 - ES2022 added [flag `d`](https://github.com/tc39/proposal-regexp-match-indices) (`hasIndices`), which provides start/end indices for matched substrings.
-- ES2024 added [flag `v`](https://github.com/tc39/proposal-regexp-v-flag) (`unicodeSets`) \[[*explainer*](https://v8.dev/features/regexp-v-flag)] as an upgrade to flag `u` (can't be used together), which adds a set of multicharacter "properties of strings" to `\p{…}`, multicharacter elements within character classes via `\p{…}` and `\q{…|…}`, nested character classes, set operators `[…--…]` and `[…&&…]`, and different escaping rules within character classes. It also fixes case-insensitive matching for doubly-negated `[^\P{…}]`.
