Does this mean libraries will no longer need to output a cjs bundle? (if supporting only node20+). Impressive job indeed, love it when things get backported :)

This would allow package maintainers to stop worrying about dual shipping from April (when 18.x goes EOL), also then TypeScript 5.9 can ship --module node20 for people to generate code that can assume require(esm) interop and make things less crazy

Node20 will reach end-of-life (EOL) in April of 2026. As a result we have started the deprecation process of Node20 for GitHub Actions. We plan to migrate all actions to run on Node24 in the fall of 2025. The newest GitHub runner (v2.328.0) now supports both Node20 and Node24 and uses Node20 as the default version. If you’d like to test Node24 ahead of time, set FORCE_JAVASCRIPT_ACTIONS_TO_NODE24=true as an env in your workflow or as an environment variable on your runner machine to force the use of Node24.

Node20のもPuppetierの新バージョン移行が促されていたので新たに並行運用で作成。

Gotta give credit to GitHub Copilot and Claude 3.7.
Tried to upgrade a rarely touched Lambda from node v16 to v22. Spent 20 confused minutes when it wouldn't process an invocation.
Asked the Q to Claude and quickly learned that node20 introduced filename case sensitivity. 🤦♀️ Oops.
