v0.4.5 - Feb 7th 2012

  • Prioritized update: Corrected issue which would cause sockets to stay open longer than necessary, and resource leakage because of this. [einaros]

v0.4.2 - Feb 4th 2012

  • Breaking change: WebSocketServer's verifyOrigin option has been renamed to verifyClient. [einaros]

  • Split benchmark, in preparation for more thorough case. [einaros]
  • Introduced hixie-76 draft support for server, since Safari (iPhone / iPad / OS X) and Opera still aren't updated to use Hybi. [einaros]
  • Expose 'supports' object from WebSocket, to indicate e.g. the underlying transport's support for binary data. [einaros]
  • Test and code cleanups. [einaros]

v0.4.1 - Jan 25th 2012

  • Use readline in wscat [tricknotes]
  • Refactor _state away, in favor of the new _readyState [tricknotes]
  • travis-ci integration [einaros]
  • Fixed race condition in testsuite, causing a few tests to fail (without actually indicating errors) on travis [einaros]

  • Enabled running of WebSocketServer in noServer-mode, meaning that upgrades are passed in manually. [einaros]
  • Reworked connection procedure for WebSocketServer, and cleaned up tests. [einaros]

v0.4.0 - Jan 2nd 2012

  • Extensive WebSocket / WebSocketServer cleanup, including changing all internal properties to unconfigurable, unenumerable properties [einaros]
  • Receiver modifications to ensure even better performance with fragmented sends [einaros]
  • Fixed issue in sender.js, which would cause SlowBuffer instances (such as returned from the crypto library's randomBytes) to be copied (and thus be dead slow) [einaros]
  • Removed redundant buffer copy in sender.js, which should improve server performance [einaros]

v0.3.7 - Dec 25nd 2011

  • Added a browser based API which uses EventEmitters internally [3rd-Eden]
  • Expose request information from upgrade event for websocket server clients [mmalecki]

v0.3.5 - Dec 13th 2011

  • Optimized Sender.js, Receiver.js and
  • Apply loop-unrolling-like small block copies rather than use node.js Buffer#copy() (which is slow).

  • Leak fixes and code cleanups.

v0.3.3 - Dec 12th 2011

  • Compile fix for Linux.
  • Rewrote parts of WebSocket.js, to avoid try/catch and thus avoid optimizer bailouts.

v0.3.2 - Dec 11th 2011

  • Further performance updates, including the additions of a native BufferUtil module, which deals with several of the cpu intensive WebSocket operations.

v0.3.1 - Dec 8th 2011

  • Service release, fixing broken tests.

v0.3.0 - Dec 8th 2011

  • Node.js v0.4.x compatibility.
  • Code cleanups and efficiency improvements.
  • WebSocket server added, although this will still mainly be a client library.
  • WebSocket server certified to pass the Autobahn test suite.
  • Protocol improvements and corrections - such as handling (redundant) masks for empty fragments.
  • 'wscat' command line utility added, which can act as either client or server.

v0.2.6 - Dec 3rd 2011

  • Renamed to 'ws'. Big woop, right -- but easy-websocket really just doesn't cut it anymore!

v0.2.5 - Dec 3rd 2011

  • Rewrote much of the WebSocket parser, to ensure high speed for highly fragmented messages.
  • Added a BufferPool, as a start to more efficiently deal with allocations for WebSocket connections. More work to come, in that area.
  • Updated the Autobahn report, at, with comparisons against WebSocket-Node 1.0.2 and Chrome 16.

v0.2.0 - Nov 25th 2011

  • Major rework to make sure all the Autobahn test cases pass. Also updated the internal tests to cover more corner cases.

v0.1.2 - Nov 14th 2011

  • Back and forth, back and forth: now settled on keeping the api (event names, methods) closer to the websocket browser api. This will stick now.
  • Started keeping this history record. Better late than never, right?
