0.18 (2013-01-28)

Features added

• 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 whenarithmetic with C ints overflow. This has a modest performance penalty, butis 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.

Bugs fixed

• Automatic C++ exception mapping didn’t work in nogil functions (only in“with nogil” blocks).
