  Update the encoding package's search function to use absolute imports when
  calling __import__.  This helps make the expected search locations for encoding
  modules be more explicit.
  
  One could use an explicit value for __path__ when making the call to __import__
  to force the exact location searched for encodings.  This would give the most
  strict search path possible if one is worried about malicious code being
  imported.  The unfortunate side-effect of that is that if __path__ was modified
  on 'encodings' on purpose in a safe way it would not be picked up in future
  __import__ calls.

 *Release date: XX-XXX-200X*
 
+- Corrected some bugs in AutoComplete.  Also, Page Up/Down in ACW implemented;
+  mouse and cursor selection in ACWindow implemented; double Tab inserts
+  current selection and closes ACW (similar to double-click and Return); scroll
+  wheel now works in ACW.  Added AutoComplete instructions to IDLE Help.
+
+- AutoCompleteWindow moved below input line, will move above if there
+  isn't enough space.  Patch 1621265 Tal Einat
+
+- Calltips now 'handle' tuples in the argument list (display '<tuple>' :)
+  Suggested solution by Christos Georgiou, Bug 791968.
+
+- Add 'raw' support to configHandler. Patch 1650174 Tal Einat.

+
+	The AutoCompleteWindow (ACW) will open after a predefined delay
+	(default is two seconds) after a '.' or (in a string) an os.sep is
+	typed.  If after one of those characters (plus zero or more other
+	characters) you type a Tab the ACW will open immediately if a possible
+	continuation is found.
+
+	If there is only one possible completion for the characters entered, a
+	Tab will supply that completion without opening the ACW.
+
+	'Show Completions' will force open a completions window.  In an empty
+	string, this will contain the files in the current directory.  On a
+	blank line, it will contain the built-in and user-defined functions and
+	classes in the current name spaces, plus any modules imported.  If some
+	characters have been entered, the ACW will attempt to be more specific.
+
+	If string of characters is typed, the ACW selection will jump to the
+	entry most closely matching those characters. Entering a Tab will cause
+	the longest non-ambiguous match to be entered in the Edit window or
+	Shell.  Two Tabs in a row will supply the current ACW selection, as
+	will Return or a double click.  Cursor keys, Page Up/Down, mouse
+	selection, and the scrollwheel all operate on the ACW.
+
+	'Hidden' attributes can be accessed by typing the beginning of hidden
+	name after a '.'.  e.g. '_'.  This allows access to modules with
+	'__all__' set, or to class-private attributes.
+
+	Completions and the 'Expand Word' facility can save a lot of typing!
+
+	Completions are currently limited to those in the namespaces.  Names in

 Also, every dictionary iterates at least twice, once for the memset()
 when it is created and once by dealloc().
 
+Dictionary operations involving only a single key can be O(1) unless 
+resizing is possible.  By checking for a resize only when the 
+dictionary can grow (and may *require* resizing), other operations
+remain O(1), and the odds of resize thrashing or memory fragmentation
