Version 4.0.0 of ws was just published.

Dependency	ws
Current Version	3.3.3
Type	dependency

The version 4.0.0 is not covered by your current version range.

If you don’t accept this pull request, your project will work just like it did before. However, you might be missing out on a bunch of new features, fixes and/or performance improvements from the dependency update.

It might be worth looking into these changes and trying to get this project onto the latest version of ws.

If you have a solid test suite and good coverage, a passing build is a strong indicator that you can take advantage of these changes directly by merging the proposed change into your project. If the build fails or you don’t have such unconditional trust in your tests, this branch is a great starting point for you to work on the update.

Release Notes

4.0.0

Breaking changes

• The close status code is now set to 1005 if the received close frame contains
  no status code (a31b1f6).
• Error messages and types have been updated (695c5ea).
• The onerror event handler now receives an ErrorEvent instead of JavaScript
  error (63e275e).
• The third argument of WebSocket.prototype.ping() and
  WebSocket.prototype.pong() is no longer a boolean but an optional callback
  (30c9f71).
• The non-standard protocolVersion and bytesReceived attributes have been
  removed (7f8ebc6...ee9b5f3).
• The extensions attribute is no longer an object but a string representing
  the extensions selected by the server (fdec524).
• The 'headers' event on the client has been renamed to 'upgrade'. Listeners
  of this event now receive only the response argument (1c783c2).
• The WebSocket.prototype.pause() and WebSocket.prototype.resume() methods
  have been removed to prevent the user from interfering with the state of the
  underlying net.Socket stream (a206e98).
