These changes make it incompatible with draft-hixie-thewebsocketprotocol-75; a client implementation of -75 can’t talk with a server implementation of -76, and vice versa. </div><div><br /></div><div>Developers should be aware that starting from WebKit nightly build r59903 and Chrome 6.0.414.0 (r47952), the client will talk to a server using -76 version of the protocol, so it will fail to open WebSocket connections with a WebSocket server based on draft-hixie-thewebsocketprotocol-75. Since -75 version of the protocol is obsoleted and no longer supported in future version of browsers, to support new clients you need to update the server implementation. (Note that Chrome 5 uses -75 version of protocol).</div><div><br /></div><div>The WebSocket protocol is still actively being changed. Until there is more consensus, we will continue to update our implementation to follow the latest draft of specification, rather than worrying about breaking changes.</div><div><br /></div><div>We’re more than happy to hear your feedback, and encourage you to file any bugs you find on our <a href="http://bugs.chromium.org/">issue tracker</a>.</div><div><br /></div><span class="post-author">Posted by Fumitoshi Ukai (鵜飼文敏), Software Engineer</span> <span itemprop='author' itemscope='itemscope' itemtype='http://schema.org/Person'> <meta content='https://plus.google.com/116899029375914044550' itemprop='url'/> </span> </noscript> </div> </div> <div class='share'> <span class='twitter-custom social-wrapper' data-href='http://twitter.com/share?text=Chromium Blog:WebSocket Protocol Updated&url=https://blog.chromium.org/2010/06/websocket-protocol-updated.html&via=ChromiumDev'> <img alt='Share on Twitter' height='24' src='https://www.gstatic.com/images/icons/material/system/2x/post_twitter_black_24dp.png' width='24'/> </span> <span class='fb-custom social-wrapper' data-href='https://www.facebook.com/sharer.php?u=https://blog.chromium.org/2010/06/websocket-protocol-updated.html'> <img alt='Share on Facebook' height='24' src='https://www.gstatic.com/images/icons/material/system/2x/post_facebook_black_24dp.png' width='24'/> </span> </div> <div class='post-footer'> <div class='cmt_iframe_holder' data-href='https://blog.chromium.org/2010/06/websocket-protocol-updated.html' data-viewtype='FILTERED_POSTMOD'></div> <a href='https://plus.google.com/112374322230920073195' rel='author' style='display:none;'> Google </a> <div class='label-footer'> <span class='labels-caption'> Labels: </span> <span class='labels'> <a class='label' href='https://blog.chromium.org/search/label/websockets' rel='tag'> websockets </a> </span> </div> </div> </div> <div class='post' data-id='7619714792016433254' itemscope='' itemtype='http://schema.org/BlogPosting'> <h2 class='title' itemprop='name'> <a href='https://blog.chromium.org/2009/12/web-sockets-now-available-in-google.html' itemprop='url' title='Web Sockets Now Available In Google Chrome'> Web Sockets Now Available In Google Chrome </a> </h2> <div class='post-header'> <div class='published'> <span class='publishdate' itemprop='datePublished'> Wednesday, December 9, 2009 </span> </div> </div> <div class='post-body'> <div class='post-content' itemprop='articleBody'> <script type='text/template'> <div>Starting in the Google Chrome <a href="http://www.chromium.org/getting-involved/dev-channel">developer channel</a> release 4.0.249.0, Web Sockets are available and enabled by default.
