   http://bugs.jquery.com/ticket/1450

0.3.2
=====

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

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.

   Opera to messup history.

 * 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.

   instead of 2000 error.

 * #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.

   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
