Version 0.75 (2011-04-12)
-------------------------

 * IP('::/0').netmask() gives IP('::') instead of IP('0.0.0.0')

Version 0.74 (2011-02-16)
-------------------------

 * Fix tests for Python 3.1 and 3.2
 * ip.__nonzero__() and (ipa in ipb) return a bool instead of 0 or 1
 * IP('0.0.0.0/0') + IP('0.0.0.0/0') raises an error, fix written by Arfrever

Version 0.73 (2011-02-15)
-------------------------

 * Support Python 3: setup.py runs 2to3
 * Update the ranges for IPv6 IPs
 * Fix reverseName() and reverseNames() for IPv4 in IPv6 addresses
 * Drop support of Python < 2.5

Version 0.72 (2010-11-23)
-------------------------

 * Include examples and MANIFEST.in in source build (add them to
   MANIFEST.in)
 * Remove __rcsid__ constant from IPy module

Version 0.71 (2010-10-01)
-------------------------

 * Use xrange() instead of range()
 * Use isinstance(x, int) instead of type(x) == types.IntType
 * Prepare support of Python3 (use integer division: x // y)
 * Fix IP(long) constructor: ensure that the address is not too large
 * Constructor raise a TypeError if the type is not int, long,
   str or unicode
 * 223.0.0.0/8 is now public (belongs to APNIC)

Version 0.70 (2009-10-29)
-------------------------

 * New "major" version because it may break compatibility
 * Fix __cmp__(): IP('0.0.0.0/0') and IP('0.0.0.0') are not equal
 * Fix IP.net() of the network "::/0": "::" instead of "0.0.0.0".
   IPy 0.63 should fix this bug, but it wasn't.

Version 0.64 (2009-08-19)
-------------------------

 * Create MANIFEST.in to fix setup.py bdist_rpm, fix by Robert Nickel

Version 0.63 (2009-06-23)
-------------------------

 * Fix formatting of "IPv4 in IPv6" network, eg. IP('::ffff:192.168.10.0/120'),
   the netmask ("/120" in the example) was missing!

Version 0.62 (2008-07-15)
-------------------------

 * Fix reverse DNS of IPv6 address: use ".ip6.arpa." suffix instead of
   deprecated ".ip6.int." suffix

Version 0.61 (2008-06-12)
-------------------------

 * Patch from Aras Vaichas allowing the [-1] operator
   to work with an IP object of size 1.

Version 0.60 (2008-05-16)
-------------------------

 * strCompressed() formats '::ffff:a.b.c.d' correctly
 * Use strCompressed() instead of strFullsize() to format IP addresses,
   ouput is smarter with IPv6 address
 * Remove check_addr_prefixlen because it generates invalid IP address
