Change log for the astroid package (used to be astng)
=====================================================

2014-07-25  --  1.2.0

    * Function nodes can detect decorator call chain and see if they are
      decorated with builtin descriptors (`classmethod` and `staticmethod`).
   
    * infer_call_result called on a subtype of the builtin type will now
      return a new `Class` rather than an `Instance`.

    * `Class.metaclass()` now handles module-level __metaclass__ declaration
      on python 2, and no longer looks at the __metaclass__ class attribute on
      python 3.

    * Function nodes can detect if they are decorated with subclasses
      of builtin descriptors when determining their type
      (`classmethod` and `staticmethod`).

    * Add `slots` method to `Class` nodes, for retrieving
      the list of valid slots it defines.

    * Expose function annotation to astroid: `Arguments` node
      exposes 'varargannotation', 'kwargannotation' and 'annotations'
      attributes, while `Function` node has the 'returns' attribute.

    * Backported most of the logilab.common.modutils module there, as
      most things there are for pylint/astroid only and we want to be
      able to fix them without requiring a new logilab.common release

    * Fix names grabed using wildcard import in "absolute import mode" 
      (ie with absolute_import activated from the __future__ or with 
      python 3). Fix pylint issue #58.

    * Add support in pylint-brain for understanding enum classes.

2014-04-30  --  1.1.1
    * `Class.metaclass()` looks in ancestors when the current class
      does not define explicitly a metaclass.

    * Do not cache modules if a module with the same qname is already
      known, and only return cached modules if both name and filepath
      match. Fixes pylint Bitbucket issue #136.

2014-04-18  --  1.1.0
    * All class nodes are marked as new style classes for Py3k.

    * Add a `metaclass` function to `Class` nodes to
      retrieve their metaclass.

    * Add a new YieldFrom node.

    * Add support for inferring arguments to namedtuple invocations.

    * Make sure that objects returned for namedtuple
      inference have parents.

    * Don't crash when inferring nodes from `with` clauses
      with multiple context managers. Closes #18.

    * Don't crash when a class has some __call__ method that is not
      inferable. Closes #17.

    * Unwrap instances found in `.ancestors()`, by using their _proxied
      class.



2013-10-18  --  1.0.1
    * fix py3k/windows installation issue (issue #4)

    * fix bug with namedtuple inference (issue #3)

    * get back gobject introspection from pylint-brain

    * fix some test failures under pypy and py3.3, though there is one remaining
      in each of these platform (2.7 tests are all green)



2013-07-29  --  1.0.0
    * Fix some omissions in py2stdlib's version of hashlib and
      add a small test for it.

    * Properly recognize methods annotated with abc.abstract{property,method}
      as abstract.

    * Allow transformation functions on any node, providing a
      `register_transform` function on the manager instead of the
     `register_transformer` to make it more flexible wrt node selection

    * Use the new transformation API to provide support for namedtuple
      (actually in pylint-brain, closes #8766)

    * Added the test_utils module for building ASTs and
      extracting deeply nested nodes for easier testing.

    * Add support for py3k's keyword only arguments (PEP 3102)

    * RENAME THE PROJECT to astroid

      ast as well (not doing it will much probably cause crash later)

    * somewhat fix #57299 and other similar issue: Exception when
      trying to validate file using PyQt's PyQt4.QtCore module: we can't
      do much about it but at least catch such exception to avoid crash

       source code or C-compiled object)



2010-09-10  --  0.20.2
    * fix astng building bug: we've to set module.package flag at the node
      creation time otherwise we'll miss this information when infering relative
      import during the build process (this should fix for instance some problems
      with numpy)

    * added __subclasses__ to special class attribute

    * fix Class.interfaces so that no InferenceError raised on empty __implements__

    * fix #19641: "maximum recursion depth exceeded" messages w/ python 2.6
      this was introduced by a refactoring

    * Ned Batchelder patch to properly import eggs with Windows line
      endings.  This fixes a problem with pylint not being able to
      import setuptools.

    * Winfried Plapper patches fixing .op attribute value for AugAssign nodes,
      visit_ifexp in nodes_as_string

    * Edward K. Ream / Tom Fleck patch closes #19641 (maximum recursion depth

    * grrr, fixed python 2.3 incompatibility introduced by generator expression
      scope handling

    * fix [Class|Module].block_range method (this fixes pylint's inline

      (close #10434)

    * multiple inference related bug fixes

    * associate List, Tuple and Dict and Const nodes to their respective
      classes

    * new .ass_type method on assignment related node, returning the
      assignment type node (Assign, For, ListCompFor, GenExprFor,
      TryExcept)

    * more API refactoring... .resolve method has disappeared, now you
      have .ilookup on every nodes and .getattr/.igetattr on node
      supporting the attribute protocol

    * introduced a YES object that may be returned when there is ambiguity
      on an inference path (typically function call when we don't know
      arguments value)

    * builder try to instantiate builtin exceptions subclasses to get their
      instance attribute



2006-01-10  --  0.14.0
    * some major inference improvements and refactoring ! The drawback is
      the introduction of some non backward compatible change in the API
      but it's imho much cleaner and powerful now :)

    * new boolean property .newstyle on Class nodes (implements #10073)

    * new .import_module method on Module node to help in .resolve
      refactoring

    * .instance_attrs has list of assignments to instance attribute

    * fix so that module names are always absolute

    * fix .resolve on package where a subpackage is imported in the
      __init__ file

    * fix a bug regarding construction of Function node from living object
      with earlier version of python 2.4

    * fix a NameError on Import and From self_resolve method

    * fix a bug occurring when building an astng from a living object with
      a property

    * lint fixes



2005-11-07  --  0.13.1
    * fix bug on building from living module the same object in
      encountered more than once time (e.g. builtins.object) (close #10069)

    * fix bug in Class.ancestors() regarding inner classes (close #10072)

    * fix .self_resolve() on From and Module nodes to handle package
      precedence over module (close #10066)

    * astng provide GenExpr and GenExprFor nodes with python >= 2.4
      (close #10063)

    * fix python2.2 compatibility (close #9922)

    * link .__contains__ to .has_key on scoped node to speed up execution

    * remove no more necessary .module_object() method on From and Module
      nodes

    * normalize parser.ParserError to SyntaxError with python 2.2



2005-10-21  --  0.13.0
    * .locals  and .globals on scoped node handle now a list of references
       to each assignment statements instead of a single reference to the
       first assignment statement.

    * fix bug with manager.astng_from_module_name when a context file is
      given (notably fix ZODB 3.4 crash with pylint/pyreverse)

    * fix Compare.as_string method

    * fix bug with lambda object missing the "type" attribute

    * some minor refactoring

    * This package has been extracted from the logilab-common package, which
      will be kept for some time for backward compatibility but will no
      longer be maintained (this explains that this package is starting with
      the 0.13 version number, since the fork occurs with the version
      released in logilab-common 0.12).
