Private symbols did not achieve consensus. The current class fields proposal remains unchanged.

[jridgewell]

Simplifying Set constructor will be pursued as a normative PR.

Richer keys to Stage 2

This proposal is still in list of stage 1 proposals, though there is new collection normalisation proposal which is on stage 2. Where did it come from? Was it separated from Richer Keys proposal?

[jridgewell]

They were both in 1 repo when it was presented. Composite keys was not discussed at the meeting. Rekey reached stage 2

Not sure exactly where to ask this, but is there any plan for implementing Object.fromEntries() in Babel? It's in Stage 4 and I can't see any mention of it anywhere in regards to transforming.

[nicolo-ribaudo]

It's implemented in core-js@3, and will be added to Babel by https://github.com/babel/babel/pull/7646

[DM2489]

I'd also like to request information on when array.prototype.flat will be added to Babel?

[TrySound]

@DM2489 Available in core-js 3

[DM2489]

Okay, I'm looking to move from @babel\pollyfill to core-js 3, but there is not dist/pollyfill.js file in there for me to use (I need to use the pollyfills in the browser) :(

Edit - for anyone that comes aross this and needs the bundled version of core-js, use core-js-bundle instead.
