+
+### Notable changes
+
+* **doc**:
+  * The JSON variant of the API documentation is no longer experimental (Rich Trott) [#27842](https://github.com/nodejs/node/pull/27842).
+* **esm**:
+  * JSON module support is always enabled under `--experimental-modules`. The
+    `--experimental-json-modules` flag has been removed (Myles Borins) [#27752](https://github.com/nodejs/node/pull/27752).
+* **http,http2**:
+  * A new flag has been added for overriding the default HTTP server socket
+    timeout (which is two minutes). Pass `--http-server-default-timeout=milliseconds`
+    or `--http-server-default-timeout=0` to respectively change or disable the timeout.
+    Starting with Node.js 13.0.0, the timeout will be disabled by default (Ali Ijaz Sheikh) [#27704](https://github.com/nodejs/node/pull/27704).
+* **inspector**:
+  * Added an experimental `--heap-prof` flag to start the V8 heap profiler
+    on startup and write the heap profile to disk before exit (Joyee Cheung) [#27596](https://github.com/nodejs/node/pull/27596).
+* **stream**:
+  * The `readable.unshift()` method now correctly converts strings to buffers.
+    Additionally, a new optional argument is accepted to specify the string's
+    encoding, such as `'utf8'` or `'ascii'` (Marcos Casagrande) [#27194](https://github.com/nodejs/node/pull/27194).
+* **v8**:
+  * The object returned by `v8.getHeapStatistics()` has two new properties:
+    `number_of_native_contexts` and `number_of_detached_contexts` (Yuriy Vasiyarov) [#27933](https://github.com/nodejs/node/pull/27933).
