Corepack is breaking backward compatibility by ending support for Node.js 20 and 25, while requiring NODE_USE_ENV_PROXY for proxy functionality going forward.

Corepack's new engine support matrix [1] [2] marks a significant shift in maintenance strategy, dropping two actively-used versions and moving to built-in proxy support that requires explicit environment configuration. This is a forcing function for teams still on Node 20 to plan their migration timeline now. Undici 8.3.0 landed this morning [3] with a critical fix that preserves pool capacity after removing stale clients [3], addressing a connection stability issue that affected production workloads. The release also fixes a race condition in test suites on Windows [4] where listeners registered after connection initiation could miss events. Over on nodejs.org, the dev team merged a lint toolchain refresh [5] bumping ESLint to 10.2.1, TypeScript-ESLint to 8.59.1, and Prettier to 3.8.3, plus React component library updates [6] to 19.2.6. Playwright test infrastructure got a Windows fix in 1.59.1 [7] that restores codegen and UI functionality after a console window regression.
