PEPs 273+302 have landed.

New ideas:

  - Add reST?

  - Fix new-style pickling

  - Remove __safe_for_unpickling__

+    - reST is going to be used a lot in Zope3.  Maybe it could become
+      a standard library module?
+
+    - I really, really, really would like to improve pickling of
+      new-style classes.
+
+      I've finally come to the conclusion that any solution to making
+      pickled new-style class instances (and hence pickled datetime
+      objects) more efficient will require adding new codes to the
+      pickle protocol.
+
+      We can do that in Python 2.3.  Because this is backwards
+      incompatible, I propose that you have to request this protocol
+      explicitly.  I propose to "upgrade' the binary flag to a general
+      "protocol version" flag, with values:
+
+        0 - original protocol
+        1 - binary protocol
+        2 - new protocol
+
+      The new protocol can contain an explicit pickle code for the new
+      datetime objects.  That's about all the thinking I've done so
+      far.  We need to decide on the new format, but first we must
+      figure out ways how to efficiently pickle and unpickle subclass
+      instances of (picklable) built-in types, preferably without
+      having to copy all the data twice, and instances of new-style
+      classes with slots.  And we need to implement these twice: in
+      Python for pickle.py and in C for cPickle.py.
+
+    - I'd also like to get rid of __safe_for_unpickling__ and all
+      other pseudo security features.  Attempting to unpickle pickles
+      from an untrusted source is insane, and nothing can help us
+      there; I'd rather make the marshal protocol bulletproof (all it
+      needs is a few more checks for inconsistent data and a little
+      better error handling).
+
     - For a class defined inside another class, the __name__ should be
       "outer.inner", and pickling should work.
