+co_flags.CO_NOFREE is now always set correctly by the code object
+constructor based on freevars and cellvars, rather than needing to be set
+correctly by the caller. This ensures it will be cleared automatically when
+additional cell references are injected into a modified code object and
+function.

+Fixed several issues in printing tracebacks (PyTraceBack_Print()).
+
+* Setting sys.tracebacklimit to 0 or less now suppresses printing tracebacks.
+* Setting sys.tracebacklimit to None now causes using the default limit.
+* Setting sys.tracebacklimit to an integer larger than LONG_MAX now means using
+  the limit LONG_MAX rather than the default limit.
+* Fixed integer overflows in the case of more than 2**31 traceback items on
+  Windows.
+* Fixed output errors handling.
