Announcing Tornado 5.1b1
<http://groups.google.com/group/python-tornado/t/fe8465beb656bcf?utm_source=digest&utm_medium=email>
I've just uploaded a beta version of Tornado 5.1. This is a transitional
release to prepare for Tornado 6.0 which will drop support for Python 2 and
remove some older APIs.
Tornado 5.1 adds deprecation warnings for everything that is going away. If
your application works on Python 3.5+ and Tornado 5.1 without warnings when
using the environment variable `PYTHONWARNINGS=d`, you should be able to
upgrade to Tornado 6.0 without difficulty. If not, you may need to pin your
dependency to Tornado 5.x.
Specifically, the stack_context module and nearly all callback arguments
are being removed in Tornado 6.0 in favor of coroutines. Full details are

To install the beta, use
pip install --pre tornado==5.1b1
