+The Transaction API will probably change a lot in the future.  For
+now, the base Transaction object doesn't know about the metadata
+fields that ZODB stores in the database.  Instead, those are defined
+in ZODB.ZTransaction.  There are some ugly names here, because taking
+Transaction for a top-level package prevents its use as name with
+ZODB.

+will probably diverge more over time.  The key different so far is
+that the registerDB() takes a single call.  The unused second argument
+has been removed.
+
+The TimeStamp object is different.  To convert the object to a raw
+8-byte string, call raw() instead of getting its repr().
