Log Message:
Update to 1.4, based on PR 31335 by Victor I.
Additional PLIST fixes.

Changes in 1.4:
An interesting new optimization: instances of user-defined classes
are now really supported, i.e. their attributes keep type information
and are stored quite compactly in memory.  However, it only works
so far with instances of a new type ``psyco.compact`` (which is
subclassable).  The line ``from psyco.classes import *`` has the
effect of turning your classes into psyco.compact subclasses, too.

Changes in 1.3:
Includes support for Python 2.4 (and of course still for 2.1-2.3).
As always comes with a few bug fixes, including a memory leak when
using the profiler.  Another good news is that the built-in functions
that read the local variables -- locals(), eval(), execfile(),
vars(), dir(), input() -- now work correctly!
