       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

    * fix #9588: false positive E1101 for augmented assignment



2009-03-25  --  0.19.0

2006-11-15  --  0.16.2
    * grrr, fixed python 2.3 incompatibility introduced by generator expression
      scope handling

    * upgrade to avoid warnings with logilab-common 0.21.0 (on which now
      depends so)

2006-09-25  --  0.16.1
    * python 2.5 support, patch provided by Marien Zwart

    * fix [Class|Module].block_range method (this fixes pylint's inline
      disabling of messages on classes/modules)

    * handle class.__bases__ and class.__mro__ (proper metaclass handling

    * fix locals/globals interactions when the global statement is used
      (close #10434)

    * multiple inference related bug fixes

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

    * 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

      refactoring

    * .instance_attrs has list of assignments to instance attribute

      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

      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)

    * 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).
