Breaking change regarding select_related+OneToOneField missing from release notes

Django 1.5 made changes to the way select_related interacts with OneToOneField reverse relations: https://code.djangoproject.com/ticket/13839
This is a breaking change and was not included in the release notes.
The behaviour of this interaction was previously undocumented (and had an open bug), but since it is core ORM functionality, I don't think you can fault people for relying on it.
Please document it in 1.5's release notes, preferably with its own paragraph.
