+### Notable changes
+
+* **crypto**:
+  * Added an oaepHash option to asymmetric encryption which allows users to specify a hash function when using OAEP padding (Tobias Nießen) [#28335](https://github.com/nodejs/node/pull/28335).
+* **deps**:
+  * Updated V8 to 7.6.303.29 (Michaël Zasso) [#28955](https://github.com/nodejs/node/pull/28955).
+    * Improves the performance of various APIs such as `JSON.parse` and methods
+      called on frozen arrays.
+    * Adds the [`Promise.allSettled`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise/allSettled) method.
+    * Improves support of `BigInt` in `Intl` methods.
+    * For more information: https://v8.dev/blog/v8-release-76
+  * Updated libuv to 1.31.0 (cjihrig) [#29070](https://github.com/nodejs/node/pull/29070).
+    * `UV_FS_O_FILEMAP` has been added for faster access to memory mapped files on Windows.
+    * `uv_fs_mkdir()` now returns `UV_EINVAL` for invalid filenames on Windows. It previously returned `UV_ENOENT`.
+    * The `uv_fs_statfs()` API has been added.
+    * The `uv_os_environ()` and `uv_os_free_environ()` APIs have been added.
+* **fs**:
+  * Added `fs.writev`, `fs.writevSync` and `filehandle.writev` (promise version) methods. They allow to write an array of `ArrayBufferView`s to a file descriptor (Anas Aboureada) [#25925](https://github.com/nodejs/node/pull/25925), (cjihrig) [#29186](https://github.com/nodejs/node/pull/29186/files).
+* **http**:
+  * Added three properties to `OutgoingMessage.prototype`: `writableObjectMode`, `writableLength` and `writableHighWaterMark` [#29018](https://github.com/nodejs/node/pull/29018).
+* **stream**:
+  * Added an new property `readableEnded` to readable streams. Its value is set to `true` when the `'end'` event is emitted. (Robert Nagy) [#28814](https://github.com/nodejs/node/pull/28814).
+  * Added an new property `writableEnded` to writable streams. Its value is set to `true` after `writable.end()` has been called. (Robert Nagy) [#28934](https://github.com/nodejs/node/pull/28934).
