Excited to finally ship the graph implementation that @lettertwo and team worked on! Some serious engineering went into this. It's a custom data structure backed by SharedArrayBuffer with similar perf to native v8 hash maps but with no serialization cost to send between threads!

A new implementation of ES Modules landed on Node master, behind a flag. It allows using ESM with the traditional .js file extension.

The new ESM implementation just landed in @nodejs core Still behind a flag, still work to be done... but an amazing accomplishment. Thank you so much everyone who has helped with getting this over the finish line. github.com/nodejs/node/pull/…
