-- Autogenerate feature is implemented in a rudimentary

+- Autogenerate feature is implemented and has been 
+  tested, though only a little bit in a production setting.
+  In particular, detection of type and server 
+  default changes are optional and are off by default;
+  they can also be customized by a callable.
+  Both features work but can have surprises particularly
+  the disparity between BIT/TINYINT and boolean,
+  which hasn't yet been worked around, as well as 
+  format changes performed by the database on defaults
+  when it reports back.  When enabled, the PG dialect 
+  will execute the two defaults to be compared to 
+  see if they are equivalent.  Other backends may 
+  need to do the same thing.

+  The autogenerate feature only generates 
+  "candidate" commands which must be hand-tailored 
+  in any case, so is still a useful feature and 
+  is safe to use.  Please report missing/broken features
   of autogenerate!  This will be a great feature and
   will also improve SQLAlchemy's reflection services.
