we've pushed new releases:
Besides accumulated smaller fixes, these releases now provide initial support for WAMP-over-Longpoll.
That means: WAMP in browsers lacking WebSocket support (and without using a Flash fallback) - such as IE9 or old Android Webkit.
To test with Crossbar.io:
pip install -U crossbar
crossbar init --template longpoll
and open http://localhost:8080 in Chrome and IE9. See the attached screenshot.
Also, AutobahnJS is now available for Bower (https://github.com/tavendo/AutobahnJS/#get-it) and older releases are hosted as well.
PS: I have tested this with IE9 only. This should work in principle with other browsers lacking WebSocket as well, like IE8 - but there are general JS issues with IE8 I don't have time to track down. Help on this would be welcome!
