Hi,

here's the first (and hopefully last) beta of Cython 0.18. Please give it a
try. The final release is expected to follow soon.

http://cython.org/release/Cython-0.18b1.tar.gz

This is a feature release with the following changes:

* Named Unicode escapes ("\N{...}") are supported.

* Python functions/classes provide the special attribute "__qualname__"
  as defined by PEP 3155.

* Added a directive ``overflowcheck`` which raises an OverflowException
  when arithmetic with C ints overflows.  This has a modest performance
  penalty, but is much faster than using Python ints.

* Calls to nested Python functions are resolved at compile time.

* Type inference works across nested functions.

* ``py_bytes_string.decode(...)`` is optimised.

* C ``const`` declarations are supported in the language.


Have fun,

Stefan
