+--------------------
+NEXT_NETADDR_VERSION
+--------------------
+
+Date: not released yet
+
+---------------
+Release: 0.10.1
+---------------
+
+Date: 2024-01-02
+
+Fixed:
+
+* Get rid of some warnings
+
+Deprecated:
+
+* Deprecate the flag shorthands: ``N``, ``P`` and ``Z``. Use :data:`NOHOST`, :data:`INET_PTON`
+ and :data:`ZEROFILL` instead.
+* Deprecate importing objects from ``netaddr`` subpackages. Only importing things from the
+ top-level ``netaddr`` namespace is supported, everything else is considered private.
+
+ This has already been the case but we can use a reminder.
+* Deprecate permissive-by-default IPv4 parsing in :func:`valid_ipv4`. The ``inet_pton()``
+ semantics (with leading zeros always disallowed) will become the default. Use :data:`INET_ATON`
+ and/or :data:`ZEROFILL` flags if you need the legacy behavior.
+
+---------------
+Release: 0.10.0
+---------------
+
+Date: 2023-12-31
+
+Added:
+
+* Add an :data:`INET_ATON` flag to explicitly request ``inet_aton()`` IPv4 parsing semantics
+ from :class:`IPAddress`.
+* Add an :meth:`IPAddress.is_ipv4_private_use` convenience method.
+* Add an :meth:`IPAddress.is_global` convenience method to allow determining if an address is
+ considered globally reachable.
+* Add an :meth:`IPAddress.is_ipv6_unique_local` convenience method.
+
+Fixed:
+
+* Improve Python 3.13 compatibility, thank you John Eckersberg.
+
+Deprecated:
+
+* Deprecate Python 3.7 support.
+* Deprecate abbreviated CIDR format support in :class:`IPNetwork`
+ (``implicit_prefix=True``).
+* Deprecate accepting leading zeros when parsing IPv4 addresses in :data:`INET_PTON` mode
+ (it's been allowed on some platforms).
+
+ If you need to allow and discard leading zeros use the :data:`ZEROFILL` flag.
+
+ This change will implicit conversions from ``str`` in all relevant contexts. If you need
+ to control the IPv4 parsing mode construct :class:`IPAddress` objects explicitly.
+* Deprecate parsing IPv4 addresses permissively (``inet_aton()``-like) by default.
+
+ :data:`INET_PTON` will become the default mode.
+
+ If you need to be permissive and parse using ``inet_aton()`` semantics use the
+ :data:`INET_ATON` flag.
+
+ This change will implicit conversions from ``str`` in all relevant contexts. If you need
+ to control the IPv4 parsing mode construct :class:`IPAddress` objects explicitly.
+* Deprecate the :meth:`IPAddress.is_private` method. Migration instructions in the
+ documentation.
+
+Other:
+
+* Raise an exception if invalid flags are passed to ``IPAddress``, ``IPNetwork`` or ``IPRange``.
+* Improve the documentation substantially.
+* Update the DB files to the latest versions (2023-12-23).
+
+--------------
+Release: 0.9.0
+--------------
+
+Date: 2023-09-18
+
+Added:
+
+* Add hash capabilities to OUI (#225, amitmi704)
+
+Fixed:
+
+* **Backwards incompatible:** Handle RFC 6164 IPv6 addresses (don't reserve first IP
+ address in point-to-point subnets) ($267, Damien Claisse)
+* **Technically backwards incompatible:** Fix for is_loopback behaviour – consider
+ ``IPNetwork('::1/128')`` to be loopback (#222, #223, niels)
+* Include tutorials in source distributions (#215, Louis Sautier)
+* Fix a documentation typo (#242, Wouter)
+* Fix print syntax in the documentation to be Python 3 compatible (#221, François Magimel)
+* Fix the Sphinx syntax in the documentation (#220, François Magimel)
+
+Other:
+
+* Update the databases (#266, Jakub Stasiak)
+* Deprecate Python 3.6 (#263, Jakub Stasiak)
+* Eliminate unnecessary evals (#228, KOLANICH)
+
+--------------
+Release: 0.8.0
+--------------
+Date: 3 Jul 2020
+
+^^^^^^^^^^^^^^^^^^^^
+Changes since 0.7.20
+^^^^^^^^^^^^^^^^^^^^
+
+* Fixed weak reference support in classes with ``__slots__``
+* Added ``__bytes__`` to ``IPAddress`` for intuitive usage, thanks to Michael Belousov.
+* Added ``format()`` function to EUI, thanks to Omer Anson.
+* Added ``IPNetwork.netmask`` property setter, thanks to Naveen Nathan.
+* Added support for IABs in the ``40:D8:55`` OUI, thanks to Brian Maissy.
+* Drastically optimized ``spanning_cidr()``, thanks to Brian Maissy.
+* Fixed ``"x.x.x.x/x" in IPNetwork`` tests, thanks to xpac1985.
+* Added support for passing iterables of ``IPRange`` to ``IPSet`` and ``cidr_merge()``, based
+ on a patch by Henry Stern.
+
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Specific bug fixes addressed in this release
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+FIXED Issue 205: https://github.com/netaddr/netaddr/issues/205

+
+FIXED Issue 161: https://github.com/netaddr/netaddr/issues/161
+ - Weak reference support
+
+^^^^^^^^^^^
+Miscellanea
+^^^^^^^^^^^
+
+- The next release (0.9.0) will contain a backwards incompatible change in IPNetwork's behaviour.
+ It's connected to handling of RFC 6164 IPv6 addresses (/127 and /128): IPNetwork.broadcast will
+ return None for those and first addresses in the networks will no longer be excluded when
+ iterating IPNetwork and IPNetwork.iter_hosts(). See https://github.com/netaddr/netaddr/pull/168
+ (or temporarily reverted commit 2984c0a40a70 in this repository) to see the actual patch.
+
+---------------
+Release: 0.7.20
+---------------
+Date: 19 Jun 2020
+
+^^^^^^^^^^^^^^^^^^^^
+Changes since 0.7.19
+^^^^^^^^^^^^^^^^^^^^
+
+* Fixed returning from an iterator on Python 3.7+, by Sergey Kozlov.
+* Fixed Python 3.8 SyntaxWarning on using `is not` with a string literal, by Stefan Nordhausen.
+* Fixed DeprecationWarnings by using raw strings for escape characters used in regexes, by Sean McGinnis.
+* Improved IPGlob documentation, by obkmeta.
+* Fixed exception creation in corner cases by explicitly passing error message params as tuples, by
+ Matthias Urlichs.
+* Stopped manually replacing shebang of an included script.
+* Stopped using __file__ in all code that's expected to run in environments that don't support it
+ (like PyOxidizer-produced binaries).
+* Updated all databases included in the package.
+
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Specific bug fixes addressed in this release
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+FIXED Issue 182: https://github.com/netaddr/netaddr/issues/182
+ - test_ip_splitter_remove_prefix_larger_than_input_range fails with python 3.7
+
+FIXED Issue 206: https://github.com/netaddr/netaddr/issues/206
+ - ""is not" with a literal." SyntaxWarning
+
+FIXED Issue 198: https://github.com/netaddr/netaddr/issues/198
+ - oui databases are outdated
+
+FIXED Issue 188: https://github.com/netaddr/netaddr/issues/188
+ - Avoid use of __file__
+
+^^^^^^^^^^^
+Miscellanea
+^^^^^^^^^^^
+
+- Python 2 versions older than 2.7 and Python 3 versions older than 3.5 should be considered
+ unsupported. No incompatible code has been introduced to the best of our knowledge but
+ there's no CI infrastructure in place to verify this and if there are any issues with
+ those versions they won't be fixed.
+- Consequently, Python 2.7 and 3.5 support should be considered deprecated as 2.7 has
+ reached its end-of-life already and 3.5 will hit it soon.
+- A CI setup has been introduced which allows us to test on a variety of Python versions
+ on all Mac, Linux and Windows.

+* Implement the "!=" operator for OUI and IAB under Python2. It was already
+ working under Python3.
+
+* 64 bit EUIs could only be created from strings with "-" as a separator.

+^^^^^^^^^^^^^^^^^^^^
+
+* Performance of IPSet increased dramatically, implemented by

+
+* Various performance improvements all over the place.
+
+* netaddr is now hosted on PyPI and can be installed via pip.
+
+* Doing "10.0.0.42" in IPNetwork("10.0.0.0/24") works now.

+* IPSet has two new methods: iscontiguous() and iprange(), thanks to Louis des Landes.
+
+* Re-added the IPAddress.netmask_bits() method that was accidentally removed.

+Release: 0.7.5
+--------------
+
+Date: 5th Oct 2010
+
+^^^^^^^^^^^^^^^^^^^
+Changes since 0.7.4
+^^^^^^^^^^^^^^^^^^^
+
+* Python 3.x is now fully supported. The paint is still drying on this so
+ please help with testing and raise bug tickets when you find any issues!
+ New Issue Tracker - https://github.com/drkjam/netaddr/issues
+
+* Moved code hosting to github. History ported thanks to svn2git.
+ - (https://github.com/nirvdrum/svn2git)
+
+* All netaddr objects now use approx. 65% less memory due to the use of
+ __slots__ in classes throughout the codebase. Thanks to Stefan Nordhausen
+ and his Python guru for this suggestion!
+
+* Applied many optimisations and speedups throughout the codebase.
+
+* Fixed the behaviour of the IPNetwork constructor so it now behaves in
+ a much more sensible and expected way (i.e. no longer uses inet_aton
+ semantics which is just plain odd for network addresses).
+
+* One minor change to behaviour in this version is that the .value property
+ on IPAddress and IPNetwork objects no longer support assignment using a
+ string IP address. Only integer value assignments are now valid. The impact
+ of this change should be minimal for the majority of users.

+
+------------
+Release: 0.7
+------------
+Date: 11th Aug 2009
+
+^^^^^^^^^^^^^^^^^^^
+Changes since 0.6.x
+^^^^^^^^^^^^^^^^^^^
+
+Please Note - This release represents a major overhaul of netaddr. It breaks
+backward compatibility with previous releases. See the API documentation for
+full details of what is available.
+
+Some highlights of what has changed :-
+
+* Internal module hierarchy has been completely overhauled and redesigned. This
+ fixes up a lot of inconsistencies and problems with interdependent imports.
+ All public classes, objects, functions and constants are still published via
+ the main netaddr module namespace as in previous releases.
+
+* No more AT_* and ST_* 'constants'.
+
+* The Addr base class is gone. This removes the link between EUI and IP
+ functionality so the library is can now easily be split into distinct units
+ without many interdependencies between layer 2 and layer 3 functionality.
+
+* The use of custom descriptor classes has been completely discontinued.
+
+* Strategy classes and singleton objects have been replaced with a group of
+ strategy modules in their own netaddr.strategy namespace. Each IP or EUI
+ address object now holds a reference to a module rather than a singleton
+ object.
+
+* Many operations that were previously static class methods are now presented as
+ functions in the relevant modules. See the API documentation for details.
+
+* The IP and CIDR classes have been replaced with two new classes called
+ IPAddress and IPNetwork respectively. This name change is important as the IP
+ part of netaddr has been completed redesigned. The notion of an individual IP
+ address and an IP network or subnet has been made more obvious. IPAddress
+ objects are now true scalars and do not evaluate in a list or tuple context.
+ They also do not support any notion of a netmask or CIDR prefix; this is the
+ primary function of an IPNetwork object.
+
+* Arbitrary IP ranges and are still supported but a lot of their functionality
+ has also been exposed via handy functions.
+
+* IP globbing routines (previous known as Wildcards) have been moved into
+ their own submodule.
+
+* Added a new IPSet class which fully emulates mutable Python sets. This
+ replaces a lot of half-baked experimental classes found in 0.5.x and 0.6.x
+ such as IPRangeSet and CIDRGroup. See documentation for details.
+
+* All methods and properties that previously used or supported the 'fmt'
+ formatting property no longer do so. In all cases, objects are now returned to
+ correctly support pass through calls without side effects. It is up to the
+ user to extract data in the right format from the objects IPAddress objects
+ returned as required.
+
+* Unit tests have been completed re-written to support docstring style tests
+ bundled into test suites. These are handy as they double up as documentation
+ being combined with wiki syntax. Implemented code coverage checking using
+ coverage 3.x.
+
+* nash - a nascent shell like tool for the netaddr library (requires IPython).
+
+* Support for RFC 1924 added ;-)

+
+FIXED Issue 32 - http://code.google.com/p/netaddr/issues/detail?id=32
+
+ - Addr.__ne__ returns wrong answer
+
+--------------
+Release: 0.6.1
+--------------
+Date: 6th Apr 2009
+
+^^^^^^^^^^^^^^^^^
+Changes since 0.6
+^^^^^^^^^^^^^^^^^
+
+* Added COPYRIGHT file with details and attribution for all 3rd party files
+ bundled with netaddr.
+
+* Minimum Python version required is now 2.4.x changed from 2.3.x.
+
+ - Python 2.3 compatibility code in many sections of code have been removed.
+
+ - the @property and @staticmethod decorators are now used throughout the
+ code along with the reversed() and sorted() builtin iterators.
+
+ - A specific version check has also been added that will raise RuntimeError
+ exceptions if you run netaddr on a Python interpreter version < 2.4.x.
+
+* Integer addresses passed to the IP() and EUI() constructors no longer
+ require a mandatory second address type (AT_*) argument in most cases. This
+ is now only really required to disambiguate between IPv4/IPv6 addresses with
+ the same numerical value. The same behaviour applies to EUI-48/EUI-64
+ identifiers. A small speed boost is achieved if the 2nd address type
+ argument is explicitly provided.
+
+* IPv6 addresses returned by EUI.ipv6_link_local() now always have a subnet
+ prefix of /64.
+
+* Default sort order of aggregate classes (IPRange, CIDR and Wildcard) has
+ been changed (again). They now sort initially by first address and then
+ by network block size from largest to smallest which feels more natural.
+
+* Fixed a bug in the CIDR.abbrev_to_verbose() static method where IPv4
+ addresses with 4 octets (i.e. non-partial addresses) were being assigned
+ subnet prefixes using abbreviated rules. All complete IPv4 addresses should
+ always get a /32 prefix where it is not explicitly provided.
+
+* Abbreviated address expansion in the CIDR constructor is now optional and
+ can be controlled by a new 'expand_abbrev' boolean argument.
+
+* Added the new CIDR.summarize() static method which transforms lists of IP
+ addresses and CIDRs into their most compact forms. Great for trimming down
+ large ad hoc address lists!
+
+* Added the previous() and next() methods to the CIDR classes which return
+ the CIDR subnets either side of a given CIDR that are of the same size.
+ For the CIDR 192.0.2.0/24, previous will return 192.0.1.0/24 and next
+ will return 192.0.3.0/24. Also accepts and optional step size (default
+ is 1).
+
+* Added the supernet() method to the CIDR class which returns a generator of
+ all the subnets that contain the current CIDR found by decrementing the
+ prefixlen value for each step until it reaches zero.
+
+* Changed the way the fallback code works when the socket module is missing
+ important constants and functions.
+
+* Removed the uppercase options from the Strategy constructors and internals
+ as this behaviour can be easily replicated using the word_fmt option
+ instead and requires less code (word_fmt='%X').

+------------
+Release: 0.6
+------------
+Date: 20th Jan 2009
+
+^^^^^^^^^^^^^^^^^^^
+Changes since 0.5.x
+^^^^^^^^^^^^^^^^^^^
+
+* Namespace changes
+
+ 3 new sub namespaces have been added :-
+
+ - netaddr.eui
+
+ Currently contains IEEE OUI and IAB classes and lookup code.
+
+ - netaddr.ip
+
+ Currently contains IANA IPv4, IPv6 and IPv4 multicast lookup code.
+
+ - netaddr.core
+
+ Currently contains only a couple of classes that are shared between code in
+ netaddr.eui and netaddr.ip.
+
+ Please Note: This change is part of a two stage internal restructuring of
+ netaddr. In future releases, layer-2 MAC/EUI functionality will be separated
+ from and layer-3 IP, CIDR and Wildcard functionality. All shared code will
+ be moved to netaddr.core. When the migration is complete (expected in 0.7)
+ the netaddr.address and netaddr.strategy namespaces will be removed. Please
+ endeavour to access everything you need via the top-level netaddr namespace
+ from this release onwards. See netaddr.__all__ for details of constants,
+ objects, classes and functions intended for the public interface.
+
+* Addition of IEEE and IANA informational lookups
+
+ - the IP() and EUI() classes now have an additional info() method through
+ which contextual information about your addresses can be accessed. This
+ data is published by IANA and the IEEE respectively and sourced directly
+ from text files bundled with netaddr that are available for download
+ publicly online. Details are available in the docstring of the relevant
+ parsing classes. Subsequent netaddr releases will endeavour to keep
+ up-to-date with any updates to these files.
+
+ - the EUI() class has been updated with the addition of the OUI() and IAB()
+ classes. They provide object based access to returned via the EUI.info()
+ method. Please see API docs included with netaddr for details.
+
+ - added new NotRegisteredError exception that is raised when an EUI doesn't
+ match any currently registration entries in the IEEE registry files.
+
+* Addr() class removed from the public interface
+
+ - This class is only ever meant to be used internally and its usage may soon
+ be deprecated in favour converting it into an abstract base class in
+ future releases.
+
+* Deletion of AddrRange() class
+
+ - replaced with the more specific IPRange() class. AddrRange() wasn't
+ very useful in practice. Too much time has been spent explaining its
+ theoretical merits over its actual practicality for every day use.
+
+* Addition of new IPRange() class
+
+ - the new base class for CIDR() and Wildcard().
+
+ - a 'killer feature' of this new class are the new methods iprange(),
+ cidrs() and wildcard() which allow you to use and switch between all
+ 3 formats easily. IPRange('x', 'y').cidrs() is particularly useful
+ returning all the intervening CIDRs between 2 arbitrary IP addresses.
+
+ - IPRange() is a great place to expose several new methods available to
+ sub classes. They are issupernet(), issubnet(), adjacent() and overlaps().
+
+ - previous method called data_flavour() has been renamed (again) to a more
+ suitable format().
+
+* IP() class updates
+
+ - is_netmask() and is_hostmask() methods have been optimised and are now
+ both approximately 4 times faster than previously!
+
+ - added wildcard() and iprange() methods that return pre-initialised
+ objects of those classes based on the current netmask / subnet prefix.
+
+ - copy constructor methods ipv4() and ipv6() now preserve the value of the
+ prefixlen property now also support IPv6 options for returning IPv4-mapped
+ or IPv4-compatible IPv6 addresses.
+
+ - added new methods is_loopback(), is_private(), is_link_local(),
+ is_ipv4_mapped() and is_ipv4_compat() which are all self explanatory.
+
+ - added a bin() method which provides an IP address in the same format
+ as the standard Python bin() builtin type ('0bxxx') now available in
+ Python 2.6.x and higher.
+
+ - added a packed() method which provides an IP address in packed binary
+ string format, suitable for passing directly to Python socket calls.
+
+* nrange() generator function updates
+
+ - by default this now returns IP() objects instead of Addr() objects.
+
+* CIDR() class updates
+
+ - the 'strict_bitmask' option in the CIDR class constructor has been had a
+ name change and is now just 'strict' (less typing).
+
+ - support for Cisco ACL-style (hostmask) prefixes. Also available to the
+ IP() class. They are converted to their netmask equivalents before being
+ applied to the base address.
+
+ - added a new subnet() generator method that returns iterators to subnet
+ CIDRs found within the current CIDR object's boundaries e.g. a /24 CIDR
+ can provide address with subnet prefixes between a /25 and /32.
+
+ - added a new span() method which takes a list of IP, IPRange, CIDR and/or
+ Wildcards returning a single CIDR that 'spans' the lowest and highest
+ boundary addresses. An important property of this class is that only a
+ single CIDR is returned and that it (potentially) overlaps the start and
+ end addresses. The most important aspect of this method is that it
+ identifies the left-most set of bits that are common to all supplied
+ addresses. It is the plumbing that makes a lot of other features function
+ correctly.
+
+ - although IPv6 doesn't support the concept of a broadcast address, after
+ some pondering I've decide to add network() and broadcast() methods to the
+ CIDR class. It is an interface quirk that users expect so it has been
+ added for ease of use.
+
+ - the methods network(), broadcast(), hostmask() and netmask() have been
+ wrapped in property() builtin calls to make them appear as read-only
+ properties.
+
+* Many more MAC and IPv4 string address representation are now supported
+
+ - Improvements to both EUI and IP classes. They now accept many more valid
+ address formats than previously. Thanks for all the bugs tickets raised.
+
+* ``__repr__()`` method behaviour change
+
+ - Using ``repr()`` now assume that you have performed a ``from netaddr import *``
+ before you execute them. They no longer specify the originating namespace
+ of objects which is a bit unnecessary and a lot to read on-screen.They
+ will also be moving around within the namespace shortly anyway so its
+ best not to think of them as being anywhere other than directly below
+ netaddr itself.
+
+* 'klass' property renamed to 'fmt' (format)
+
+ - now referred to as the 'format callable' property. An unfortunately but
+ necessary change. 'klass' was a bad initial name choice as it most often
+ doesn't even reference a class object also supporting references to Python
+ types, builtin functions and user defined callables.
+
+* Complete re-work and consolidation of unit tests.
+
+ - now over 100 tests covering all aspects of the API and library
+ functionality.
+ - Moved all tests into a single file. Lots of additional tests have been
+ added along with interface checks to ensure netaddr's always presents
+ a predictable set of properties and methods across releases.
+
+* Nascent support for Python eggs and setuptools.
+
+ - Help is need to test this as it is not something I use personally.
+
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Specific bug fixes addressed in this release
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+* Finally fixed the IPv6 string address compression algorithm so that it
+ is now compliant with the socket modules inet_ntop() and inet_pton() calls.
+ (not available on all platforms).
+
+^^^^^^^^^^^^^^^^^^^^^
+Experimental Features
+^^^^^^^^^^^^^^^^^^^^^
+
+* added bitwise operators to the IP class
+
+ - does what it says on the tin. Does not effect that value of the IP object
+ itself but rather, returns a new IP after the operation has been applied.
+
+* IPRangeSet() class added (EXPERIMENTAL).
+
+ - the intention with this class is to allows you to create collections of
+ unique IP(), IPRange(), CIDR() and Wildcard() objects. It provides
+ iteration over IPs in the collection as well as several membership based
+ operations such as any_match() all_matches(), min_match() and max_match().
+ - lots more work to do here. Please raise bugs and feature requests against
+ this as you find them. Improvements to this are coming in 0.7.

+
+------------
+Release: 0.5
+------------
+Date: 19th Sep 2008
+
+^^^^^^^^^^^^^^^^^^^
+Changes since 0.4.x
+^^^^^^^^^^^^^^^^^^^
+
+**General**
+
+* Access to all important object attributes in all netaddr classes now takes
+ place via custom Python descriptor protocol classes. This has greatly
+ simplified internal class logic and made external attributes changes much
+ safer and less error prone. It has also made aggregate classes such as CIDR
+ and Wildcard effectively read-write rather than read-only which they have
+ been up until this release.
+
+* Amended the way sort order is calculated for Addr and AddrRange (sub)class
+ instances so that the address type is taken into account as well as as the
+ numerical value of the address or address range. The ascending sort order
+ is IPv4, IPv6, EUI-48 and EUI-64. Sequences of AddrRange (sub)class
+ instances now sort correctly!
+
+* Comparisons between instances of Addr and AddrRange (sub)classes now return
+ False, rather than raising an AttributeError.
+
+* Added checks and workaround code for Python runtime environments that suffer
+ from the infamous socket module inet_aton('255.255.255.255') bug. This was
+ discovered recently in Python 2.4.x on PowerPC under MacOS X. The fix also
+ applies in cases where the socket module is not available (e.g. on Google
+ App Engine).
+
+* All general Exception raising in the strategy module has now been replaced
+ with more specific exceptions, mainly ValueError (these were unintentionally
+ missed out of the 0.4 release).
+
+* Implemented __hash__() operations for the Addr and AddrStrategy classes. This
+ allows you to use IP, CIDR and Wildcard objects as keys in dictionaries and
+ as elements in sets. Please note - this is currently an experimental feature
+ which may change in future releases.
+
+* Added __ne__() operation to Addr and AddrRange classes.
+
+* Obeying the 'Law of Demeter', the address type of Addr and AddrRange
+ (sub)class instances can be accessed using the property directly :-
+
+ obj.addr_type # 0.5 onwards
+
+ rather than having to go via the strategy object :-
+
+ obj.strategy.addr_type # 0.4 and earlier
+
+* Renamed the AT_DESCR lookup dictionary to AT_NAMES. Removed invalid and
+ duplicated imports from all modules.
+
+**Addr class changes**
+
+* Removed the setvalue() method from the Addr class and replaced all uses of
+ __setattr__() replaced by custom descriptors throughout.
+
+**IP class changes**
+
+* Removed the ambiguity with masklen and prefixlen attributes in the IP class.
+ prefixlen now denotes the number of bits that define the netmask for an IP
+ address. The new method netmask_bits() returns the number of non-zero bits
+ in an IP object if the is_netmask() method returns True. A prefixlen value
+ other than /32 for an address where is_netmask() returns True is invalid
+ and will raise a ValueError exception.
+
+* Removed the family() method from the IP class. It duplicates information
+ now provided by the prefixlen property.
+
+* IP class has several new methods. is_multicast() and is_unicast() quickly
+ tell you what category of IP address you have and while ipv4() and ipv6()
+ act as IPv4 <-> IPv6 conversions or copy constructors depending on context.
+
+* Reverse DNS lookup entries now contain a trailing, top-level period (.)
+ character appended to them.
+
+* Added the hostname() method to IP instances which performs a reverse DNS
+
+* The IP class __str__() method now omits the subnet prefix is now implicit
+ for IPv4 addresses that are /32 and IPv6 addresses that are /128. Subnet
+ prefix is maintained in return value for all other values.
+
+**AddrRange class changes**
+
+* The AddrRange class no longer stores instances of Addr (sub)classes for the
+ first and last address in the range. The instance variables self.start_addr
+ and self.stop_addr have been renamed to self.first and self.last and the
+ methods obj.first() and obj.last() have been removed.
+
+ Instead, self.first and self.last contain integer values and a reference
+ to a strategy object is stored. Doing this is a lot more useful and cleaner
+ for implementing internal logic.
+
+ To get Addr (sub)class objects (or strings, hex etc when manipulating the
+ the klass property) use the index values obj[0] and obj[-1] as a substitute
+ for obj.first() and obj.last() respectively.
+
+* AddrRange (sub)class instances now define the increment, __iadd__(), and
+ decrement, __isub__(), operators. This allows you to 'slide' CIDRs and
+ Wildcards upwards and downwards based on their block sizes.
+
+* The _retval() method has now been renamed data_flavour() - yes, the UK
+ spelling ;-) You shouldn't really care much about this as it mostly for
+ internal use. I gave it a decent name as I didn't see any real need to hide
+ the functionality if users wanted it.
+
+**CIDR class changes**
+
+* The strictness of the CIDR class constructor in relation to non-zero bits
+ once the prefix bitmask has been applied can be disabled use the optional
+ argument strict_bitmask=False. It is True (strictness enabled) by default.
+
+* Fixed a bug in abbreviated CIDR conversion. Subnet prefix for multicast
+ address 224.0.0.0 is now /4 instead of /8.
+
+* The CIDR class now supports subtraction between two CIDR objects, returning
+ a list of the remainder. Please note that the bigger of the two CIDR objects
+ must be on the left hand side of the the expression, otherwise an empty list
+ is return. Sorry, you are not allowed to create negative CIDRs ;-)
+
+* The function abbrev_to_cidr() has been renamed to and turned into the static
+ method CIDR.abbrev_to_verbose(). No major changes to the logic have been
+ made.
+
+**Wildcard class changes**
+
+* The Wildcard class now defines a static method Wildcard.is_valid() that
+ allows you to perform validity tests on wildcard strings without fully
+ instantiation a Wildcard object.

+Release: 0.4
+------------
+Date: 7th Aug 2008
+
+^^^^^^^^^^^^^^^^^^^
+Changes since 0.3.x
+^^^^^^^^^^^^^^^^^^^
+
+* All general Exception raising has been replaced with more specific
+ exceptions such as TypeError and ValueError and with the addition of two
+ custom exception classes, AddrFormatError and AddrConversionError.
+
+* The IP class now accepts a subnet prefix. It is *NOT* strict about non-zero
+ bits to the right of implied subnet mask, unlike the CIDR class (see below).
+
+* The CIDR class is now completely strict about non-zero bits to the right of
+ the implied subnet netmask and raises a ValueError if they exist, with a
+ handy hint as to the correct CIDR to be used based on the supplied subnet
+ prefix.
+
+* The CIDR class now also supports abbreviated CIDR ranges and uses older
+ classful network address rules to decided on a subnet prefix if one is not
+ explicitly provided. Supported forms now include 10, 10/8 and 192.168/16.
+ Currently only supports these options for IPv4 CIDR address ranges.
+
+* __repr__() methods have been defined for all classes in the netaddr module
+ producing executable Python statements that can be used to re-create the
+ state of any object.
+
+* CIDR and Wildcard classes now have methods that support conversions between
+ these two aggregate types :-
+
+ * CIDR -> Wildcard
+ * Wildcard -> CIDR
+
+^^^^^^^^^^^^^^^^^^^^
+Housekeeping Changes
+^^^^^^^^^^^^^^^^^^^^
+
+* Massive docstring review and tidy up with the inclusino of epydoc specific
+ syntax to spruce up auto-generated API documentation.
+
+* Thorough review of code using pylint.
+
+* Netaddr module now has the special __version__ variable defined which is
+ also referenced by setup.py.
+
+* Some minor changes to setup.py and MANIFEST.in.
+
+* Constants and custom Exception classes have been moved to __init__.py from
+ strategy.py
+
+* An import * friendly __all__ has been defined for the netaddr namespace
+ which should remove the need to delve too much into the address and strategy
+ submodules.
+
+* Fixed a number of line-ending issues in several files.
