lib/_stream_readable.js

-    if (state.objectMode && (chunk === null || chunk === undefined))
-      return;
-    else if (!state.objectMode && (!chunk || !chunk.length))
-      return;


Readable should already handle all of the above. Not sure why this was put here. Legacy?

lib/_stream_readable.js

-  stream.on('resume', () => {
-    // TODO(ronag): this.resume()?
-    this.emit('resume');
-  });


I'm a little unsure what to do exactly when the wrapped stream emits pause and resume. I don't think it's relevant?

One of the big changes in npm 7 is that peer dependencies are now installed by default. Throw On Unhandled Rejections (#33021): As of Node.js 15, the default mode for `unhandledRejection` is changed to `throw` (from `warn`). In `throw` mode, if an `unhandledRejection` hook is not set, the `unhandledRejection` is raised as an uncaught exception. Users that have an `unhandledRejection` hook should see no change in behavior, and it’s still possible to switch modes using the `--unhandled-rejections=mode` process flag. QUIC (#32379): Node.js 15 comes with experimental support QUIC, which can be enabled by compiling Node.js with the `--experimental-quic` configuration flag. The Node.js QUIC implementation is exposed by the core `net` module. V8 8.6 (#35415): The V8 JavaScript engine has been updated to V8 8.6 (V8 8.4 is the latest available in Node.js 14). Along with performance tweaks and improvements the V8 update also brings the following language features: * `Promise.any()` (from V8 8.5) * `AggregateError` (from V8 8.5) * `String.prototype.replaceAll()` (from V8 8.5) * Logical assignment operators `&&=`, `||=`, and `??=` (from V8 8.5) Other Notable Changes: -
