* Allow deriving public from private keys (Tobias Nießen) [#26278](https://github.com/nodejs/node/pull/26278).
* **events**
* Added a `once` function to use `EventEmitter` with promises (Matteo Collina) [#26078](https://github.com/nodejs/node/pull/26078).
* **tty**
* Added a `hasColors` method to `WriteStream` (Ruben Bridgewater) [#26247](https://github.com/nodejs/node/pull/26247).
* Added NO\_COLOR and FORCE\_COLOR support (Ruben Bridgewater) [#26485](https://github.com/nodejs/node/pull/26485).
* **v8**
* Added `v8.getHeapSnapshot` and `v8.writeHeapSnapshot` to generate snapshots in the format used by tools such as Chrome DevTools (James M Snell) [#26501](https://github.com/nodejs/node/pull/26501).
* **worker**
* Added `worker.moveMessagePortToContext`. This enables using MessagePorts in different vm.Contexts, aiding with the isolation that the vm module seeks to provide (Anna Henningsen) [#26497](https://github.com/nodejs/node/pull/26497).
* **C++ API**
* `AddPromiseHook` is now deprecated. This API was added to fill an use case that is served by `async_hooks`, since that has `Promise` support (Anna Henningsen) [#26529](https://github.com/nodejs/node/pull/26529).
* Added a `Stop` API to shut down Node.js while it is running (Gireesh Punathil) [#21283](https://github.com/nodejs/node/pull/21283).
* **meta**
* [Gireesh Punathil](https://github.com/gireeshpunathil) is now a member of the Technical Steering Committee [#26657](https://github.com/nodejs/node/pull/26657).
* Added [Yongsheng Zhang](https://github.com/ZYSzys) to collaborators [#26730](https://github.com/nodejs/node/pull/26730).
