Skeletal version; I'm checking this in now so I can keep a list of changes,
but don't plan on actually writing any text until, ooh, say, July or thereabouts.

+\section{Introduction}
+
+{\large This document is a draft, and is subject to change until the
+final version of Python 2.2 is released. Currently it's not up to
+date at all. Please send any comments, bug reports, or questions, no
+matter how minor, to \email{amk1@bigfoot.com}. }
+
+This article explains the new features in Python 2.2.
+Python 2.2 includes some significant changes that go far toward cleaning up
+the language's darkest corners.
+
+This article doesn't attempt to provide a complete specification for
+the new features, but instead provides a convenient overview of the
+new features. For full details, you should refer to 2.2 documentation
+such as the Library Reference and the Reference Guide, or to the PEP
+for a particular new feature.
+
+The final release of Python 2.2 is planned for October 2001.

+
+ \item XXX C API: Reorganization of object calling
+
+%Original log message:
+
+%The call_object() function, originally in ceval.c, begins a new life
+%as the official API PyObject_Call(). It is also much simplified: all
+%it does is call the tp_call slot, or raise an exception if that's
+%NULL.
+
+%The subsidiary functions (call_eval_code2(), call_cfunction(),
+%call_instance(), and call_method()) have all been moved to the file
+%implementing their particular object type, renamed according to the
+%local convention, and added to the type's tp_call slot. Note that
+%call_eval_code2() became function_call(); the tp_slot for class
+%objects now simply points to PyInstance_New(), which already has the
+%correct signature.
+
+%Because of these moves, there are some more new APIs that expose
+%helpers in ceval.c that are now needed outside: PyEval_GetFuncName(),
+%PyEval_GetFuncDesc(), PyEval_EvalCodeEx() (formerly get_func_name(),
+%get_func_desc(), and eval_code2().
