    including an empty string.
  - `Buffer.fill()` will throw if an attempt is made to fill with an
    empty `Buffer`.
- Child Process
  - Undefined properties of env are ignored.
- Console
  - The `console.table()` method has been added.

- N-API
  - The n-api is no longer experimental.
- Net
  - The `'close'` event will be emitted after `'end'`.

  - The `performance` API has been simplified.
  - Performance milestone marks will be emitted as trace events.
- Process
  - Using non-string values for `process.env` is deprecated.
  - The `process.assert()` method is deprecated.
- REPL
  - REPL now experimentally supports top-level await when using the
    `--experimental-repl-await` flag.
  - The previously deprecated "magic mode" has been removed.
  - The previously deprecated `NODE_REPL_HISTORY_FILE` environment
    variable has been removed.
  - Proxy objects are shown as Proxy objects when inspected.
- Streams
  - The `'readable'` event is now always deferred with nextTick.
  - A new `pipeline()` method has been provided for building

    `stream.Readable`.
- Timers
  - The `enroll()` and `unenroll()` methods have been deprecated.
- TLS
  - The `tls.convertNPNProtocols()` method has been deprecated.
  - Support for NPN (next protocol negotiation) has been dropped.
  - The `ecdhCurve` default is now `'auto'`.
- Trace Events
  - A new `trace_events` top-level module allows trace event
    categories to be enabled/disabled at runtime.
- URL
  - The WHATWG URL API is now a global.
