• Highlights: Python 2.5

  ...import can use both relative and absolute imports when inside packages. Try/except/finally were changed so that it's now possible to have both except blocks and a finally block for the same try block. Exceptions have become new-style classes, and the exception hierarchy has been rearranged a bit. Internally, Python was changed to use the Py_ssize_t type - this means that many structures that were limited to 2^32 objects can now hold up to 2^64 instead. New or upgraded built-ins partition and r...
