------------------------------------------------------------------
Bugfixes
------------------------------------------------------------------
fix remaining potential accessor name clashes (but this only works
with Django 1.2+, for 1.1 no changes). Thanks to Andrew Ingram.
fix use of 'id' model field, replaced with 'pk'.
fix select_related bug for objects from derived classes (till now
sel.-
r. was just ignored)
------------------------------------------------------------------
"Restrictions & Caveats" updated
------------------------------------------------------------------
* Django 1.1 only - the names of polymorphic models must be unique
in the whole project, even if they are in two different apps.
This results from a restriction in the Django 1.1 "related_name"
option (fixed in Django 1.2).
* Django 1.1 only - when ContentType is used in models, Django's
seralisation or fixtures cannot be used. This issue seems to be
resolved for Django 1.2 (changeset 11863: Fixed #7052, Added
support for natural keys in serialization).
