[pypy-dev] PyPy and RinohType

[Brecht Machiels]

Hello Maciej,

Any idea when a new PyPy3 release is due? I seem to remember it was announced on Twitter some time ago, but haven't heard anything about it since. However, I suppose the next release will neither be mature?

I'll see how much trouble it is to get RinohType working on Python 2. Perhaps there's not much more to it besides overriding the builtin str and unicode.

Best regards,
Brecht
