From the July TC39 meeting [0]:

> After 7 years, Temporal is close to done. Our only focus is making sure in-progress implementations are successful, by fixing corner-case bugs found by implementors, and making editorial changes to improve clarity and simplicity.

It's not (yet) on the October TC39 agenda [1].

The Chromium implementation issue hasn't been updated since 2022. [2]

Webkit's implementation issue was updated once this year... to add a blocker [3]

V8 is passing 75% of test262's tests, and JavascriptCore is passing 41%. Spidermonkey is a no-show. [4] Note that test262 is incomplete and hasn't seen activity this year [5], so those percentages may decrease over time.

"about to be fixed" ehhhh. If it lands this year I'd be surprised.
