Release history
===============

macholib 1.7
------------

* Added support for ARM64, LC_ENCRYPTION_INFO_64 and LC_LINKER_OPTION

  Patch by Matthias Ringwald.

* Load commands now have a "describe" method that returns more information
  about the command.

  Patch by David Dorsey.

* The MAGIC value in the header was always represented in the native
  byte order, instead of as the value read from the binary.

  Patch by David Dorsey.

* Added various new constants to "macholib.mach_o".

  Patch by David Dorsey.

macholib 1.6.1
--------------

* ?

macholib 1.6
------------

* Add support for '@loader_path' link command in
  macholib.dyld:

  - Added function ``macholib.dyld.dyld_loader_search``

  - This function is used by ``macholib.dyld.dyld_find``,
    and that function now has an new (optional) argument
    with the path to the loader.

* Also add support for '@loader_path' to macholib.MachoGraph,
  using the newly added '@loader_path' support in the
  dyld module.

  Due to this suppport the *macho_standalone* tool can
  now rewrite binaries that contain an '@loader_path' load
  command.


macholib 1.5.2
--------------

* Issue #93: Show the name of the affected file in the exception message
  for Mach-O headers that are too large to relocate.


macholib 1.5.1
--------------

* There were no 'classifiers' in the package metadata due to
  a bug in setup.py.

macholib 1.5
--------------

macholib 1.5 is a minor feature release

* No longer use 2to3 to provide Python 3 support

  As a side-effect of this macholib no longer supports
  Python 2.5 and earlier.

* Adds suppport for some new macho load commands

* Fix for py3k problem in macho_standalone.py

  Patch by Guanqun Lu.

* Fix for some issues in macho_dump.py

  Patch by Nam Nguyen

* Issue #10: Fix for LC_DATA_IN_CODE linker commands, without
  this fix py2app cannot build application bundles when
  the source binaries have been compiled with Xcode 4.5.

* Issue #6: Fix for LC_ENCRYPTION_INFO linker commands

* Use the mach header information to print the cpu type of a
  binary, instead of trying to deduce that from pointer width
  and endianness.

  Changed the code because of issue #6, in which a user tries to
  dump a iOS binary which results in bogus output in the previous
  releases.

* The mapping ``macholib.macho_dump.ARCH_MAP`` is undocumented
  and no longer used by macholib itself. It will be removed
  in the next release.


* The command-line tools ``macho_find``, ``macho_dump`` and
  ``macho_standalone`` are deprecated. Use "python -mmacholib"
  instead. That is::

   $ python -mmacholib dump /usr/bin/grep

   $ python -mmacholib find ~

   $ python -mmacholib standalone myapp.app

  This makes it clearer which version of the tools are used.

macholib 1.4.3
--------------

macholib 1.4.3 is a minor feature release

* Added strings for 'x86_64' and 'ppc64' to
  macholib.mach_o.CPU_TYPE_NAMES.

* macho_find and macho_dump were broken in the 1.4.2 release

* added 'macholib.util.NOT_SYSTEM_FILES', a list of
  files that aren't system path's even though they are
  located in system locations.

  Needed to work around a bug in PySide (see issue #32 in the
  py2app tracker)



macholib 1.4.2
--------------

macholib 1.4.2 is a minor bugfix release

* The support for new load commands that was added in 1.4.1
  contained a typo that caused problems on OSX 10.7 (Lion).

macholib 1.4.1
--------------

macholib 1.4.1 is a minor feature release

Features:

- Add support for a number of new MachO load commands that were added
  during the lifetime of OSX 10.6: ``LC_LOAD_UPWARD_DYLIB``,
  ``LC_VERSION_MIN_MACOSX``, ``LC_VERSION_MIN_IPHONEOS`` and
  ``LC_FUNCTION_STARTS``.

macholib 1.4
-------------

macholib 1.4 is a feature release

Features:

- Documentation is now generated using `sphinx <http://pypi.python.org/pypi/sphinx>`_
  and can be viewed at <http://packages.python.org/macholib>.

- The repository has moved to bitbucket

- There now is a testsuite

- Private functionality inside modules was renamed to
  a name starting with an underscore.

  .. note:: if this change affects your code you are relying on undefined
     implementation features, please stop using private functions.

- The basic packable types in ``macholib.ptypes`` were renamed to better
  represent the corresponding C type. The table below lists the old
  an new names (the old names are still available, but are deprecated and
  will be removed in a future release).

  +--------------+--------------+
  | **Old name** | **New name** |
  +==============+==============+
  | p_byte       | p_int8       |
  +--------------+--------------+
  | p_ubyte      | p_uint8      |
  +--------------+--------------+
  | p_short      | p_int16      |
  +--------------+--------------+
  | p_ushort     | p_uint16     |
  +--------------+--------------+
  | p_int        | p_int32      |
  +--------------+--------------+
  | p_uint       | p_uint32     |
  +--------------+--------------+
  | p_long       | p_int32      |
  +--------------+--------------+
  | p_ulong      | p_uint32     |
  +--------------+--------------+
  | p_longlong   | p_int64      |
  +--------------+--------------+
  | p_ulonglong  | p_uint64     |
  +--------------+--------------+

  ``Macholib.ptypes.p_ptr`` is no longer present as it had an unclear
  definition and isn't actually used in the codebase.


Bug fixes:

- The semantics of ``dyld.dyld_default_search`` were changed a bit,
  it now first searches the framework path (if appropriate) and then
  the linker path, irrespective of the value of the ``DYLD_FALLBACK*``
  environment variables.

  Previous versions would change the search order when those variables
  was set, which is odd and doesn't correspond with the documented
  behaviour of the system dyld.

- It is once again possible to install using python2.5

- The source distribution includes all files, this was broken
  due to the switch to mercurial (which confused setuptools)

macholib 1.3
------------

macholib 1.3 is a feature release.

Features:

- Experimental Python 3.x support

  This version contains lightly tested support for Python 3.

macholib 1.2.2
--------------

macholib 1.2.2 is a bugfix release.

Bug fixes:

- Macholib should work better with 64-bit code
  (patch by Marc-Antoine Parent)
