ChangeLog for PyLint
====================

  --
    * new W0212 message for access to protected member from client code
    * new W0105 message extracted from W0104 (statement seems to have no effect)
      with string
	
2006-04-19  --  0.11.0
    * fix crash caused by the exceptions checker in some case
    * fix some E1101 false positive with abstract method or classes defining
      __getattr__
    
    * dirty fix to avoid "_socketobject" has not "connect" member. The actual
      problem is that astng isn't able to understand the code used to create 
      socket.socket object with exec
	
    * added an option in the similarity checker to ignore docstrings, enabled
      by default
	
    * included patch Benjamin Niemann to allow block level enabling/disabling
      of messages

	
2006-03-06  --  0.10.0
    * WARNING, this release include some configuration changes (see below),
      so you may have to check and update your own configuration file(s) if
      you use one
        
    * this release require the 0.15 version of astng or superior (it will save
      you a lot of pylint crashes...)
        
    * W0705 has been reclassified to E0701, and is now detecting more
      inheriting problem, and a false positive when empty except clause is
      following an Exception catch has been fixed (close #10422)

    * E0212 and E0214 (metaclass/class method should have mcs/cls as first
      argument have been reclassified to C0202 and C0203 since this not as
      well established as "self" for instance method (E0213)
        
    * W0224 has been reclassified into F0220 (failed to resolve interfaces
      implemented by a class)   
        
    * a new typecheck checker, introducing the following checks:
        - E1101, access to unexistant member (implements #10430), remove
          the need of E0201 and so some options has been moved from the
          classes checker to this one
        - E1102, calling a non callable object
        - E1111 and W1111 when an assigment is done on a function call but the 
          infered function returns None (implements #10431) 

    * change in the base checker:
        - checks module level and instance attribute names (new const-rgx
          and attr-rgx configuration option) (implements #10209  and
          #10440) 
        - list comprehension and generator expression variables have their
          own regular expression  (the inlinevar-rgx option) (implements
          #9146)
        - the C0101 check with its min-name-lentgh option has
          been removed (this can be specified in the regxp after all...)
        - W0103 and W0121 are now handled by the variables checker
          (W0103 is now W0603 and W0604 has been splitted into different messages)
        - W0131 and W0132 messages  have been reclassified to C0111 and
          C0112 respectivly 
        - new W0104 message on statement without effect
        
    * regexp support for dummy-variables (dummy-variables-rgx option
      replace dummy-variables) (implements #10027)
        
    * better global statement handling, see W0602, W0603, W0604 messages
      (implements #10344 and #10236)
        
    * --debug-mode option, disabling all checkers without error message
      and filtering others to only display error

2006-01-10  --  0.9.0

      style / new style classes usage problems (rely on astng 0.14 new
      style detection feature)

      from the command line or from a configuration file) (implements
      #10031)
