0.3.4

• Mentioned njoyce's fork of sockjs-gevent.

• 90 - Don't catch onbeforeunload event - it breaks javascript://

  links in IE.
• IE mangles 204 response code for 1223 on ajax, see:
  http://bugs.jquery.com/ticket/1450
• Make new optional for SockJS constructor (via substack).
• It is impossible to cancel JSONP polling request - compensate for that.
• Refactored EventEmitter prototype (used only internally)

• 66 - Failure to post data to /xhr_send should kill the session

0.3.2

• 77 - Getting /info on modern browsers when html is served from

   file:// urls was broken.
  

0.3.1

• 61 - Meteor guys found that we unintentionally catch "onopen" errors.

• 63 - Meteorjs guys found that xhr-streaming on Safari sometimes

  left busy cursor running.
• Increased allowed time for websocket transport (from 1 rtt to 2),
  this should make ws transport more reliable over SSL, at the cost
  of slightly longer connection time for users with blocked ws.

• 57 - previous fix didn't really work, sockjs-client still left

  a mess in browsers history when using iframe transports. This
  is fixed now.

• 60 - Opera 12 (next) claims to do AJAX2 / CORS, but can't

  do xhr-streaming.

• 58 - onunload test sometimes failed on Safari on windows

• Updated readme WRT websocket protocols
• Updated readme WRT deployments on heroku
• Add minimalistic license block to every source file.

0.3.0

• Temporarily disabled iframe tests - they are failing unpredictably.

• 57 - pointing an iframe to "about:blank" during cleanup caused

  Opera to messup history.

• 55 - Improved iframe abstraction (reduced a possible mem leak)

• Refactored AJAX abstractions, for better CORS handing - again.
• Add additional parent origin security check to an iframe.
• Urls with hashes or query strings can't be passed to SockJS.

• 18 - Mention workaround for Firefox ESC key issue

• 53 - AMD compliance

• sockjs/sockjs-protocol#28 - always use square brackets for
  websocket frames

• 51 - initial support for IE10 - try XHR before XDR

• 28 - handle onunload / onbeforeunload in a more robust fashion

• 49 - support SockJS-client being used from files served from

  file:// urls.

0.2.1

• "smoke-latency.html" test was unnecesairly sending too much data.
• Bumped core dependencies (coffee-script and uglify-js)
• Minor updates to the README, few cosmetic changes in the code.

0.2.0

• The API had changed - use protocols_whitelist option instead of
  passing an array of protocols as a second argument to SockJS constructor.
• Dropped 'chunking-test' functionality and replace it with 'info'.
• Rewritten protocol-choosing alogirthm, see "utils.detectProtocols" method.
• Use dynamic protocol timeouts based on RTT, not hardcoded 5 seconds

• 34 - Don't ever reuse session_id, especially when trying

  fallback protocols.
• The test server got moved from SockJS-client to SockJS-node.
• Don't test unicode surrogates - it can't work in some environments.
• XHR/XDR helpers were rewritten, ajax transports were simplified.
• Added a domain check in the iframe to improve security.
• SockJS will now trigger 1002 error if there is a problem during handshake
  instead of 2000 error.
• Smoke-throughput test is renamed to smoke-latency.

0.1.2

• 29 - Allow all unicode characters to be send over SockJS.

• 15 - SockJS should now work fine even if the connection is started

  in HEAD, before BODY is loaded.

• 28 - In rare circumstances WebSocket connection can be left intact

  after the page is unloaded in FireFox.
• Updated scripts to work with Node 0.6.
• Initial work to do better QUnit testing.
• Updated the minifying script (always escape unicode chars, remove
  trailing comment).
• Use string instead of array of chars (utils.js:random_number_string).

0.1.1

• 21 Get JsonP transport working on IE9 (Vladimir Dronnikov).

• 26 Emit heartbeat event.

• 27 Include license inline.

0.1.0

• SockJS-client can only send UTF-8 encodable strings. Previously we
  took advantage of rich data structures and automatically
  json-encoded them, but this got removed. Now, all data passed to
  send will be converted to string. This is also how native
• status property on EventClose is renamed to code
  as per Websocket API
  WebSockets behave.
• The test server was updated to new sockjs-node API
• Fixed problem with Jsonp-polling transport on IE9
• Repository was moved - updated links.

0.0.4

• All transports were refactored, some transports were introduced:
  htmlfile and separate xhr-streaming.
• Added logic to detect support for http chunking, and thus a
  possibility to rule out streaming transports before running them.
• Added 'cookie' option, useful for cookie-based load balancing
  (currently, it make a difference only for IE).
• Added hack to prevent EventSource from crashing Safari and Chrome.
• Loads and loads of other small and medium changes.

0.0.2

• Initial support for JSESSIONID based load balancing. Currently
  doesn't play nicely with IE XDomainRequest transport.

0.0.1

• Initial release.
