ECMAScript 2021 has been released.
The next version is ECMAScript 2022 (draft).

It seems "Array find from last" is implemented:
https://github.com/Samsung/escargot/blob/master/src/builtins/BuiltinArray.cpp#L1848

I think the list could be updated with it.

Is there some feature you would prefer to be implemented sooner? Temporal is currently in progress.
