Hi, we've released Crossbar.io and AutobahnPython 0.13.0, running on Twisted 16.0.0 and PyPy 5.0. Get it here: Source: * https://github.com/crossbario/crossbar * https://github.com/crossbario/autobahn-python Python Packages: * https://pypi.python.org/pypi/crossbar * https://pypi.python.org/pypi/autobahn Binary Packages (recommended) * http://crossbar.io/docs/Local-Installation/ The binary packages contain a complete, self-contained, optimized Crossbar.io with everything - including PyPy 5.0, and of course based on Twisted 16.0.0! These packages are available for Ubuntu, FreeBSD and CentOS. (thanks to Hawkie, Miss Amber Brown - she made that happen;) ) Cheers, /Tobias
