Changes between Version 6 and Version 7 of ModelSyntaxChangeInstructions

v6	v7
7	7	* Fields are now attributes of the model class, rather than members of a {{{fields}}} list.
8	8	* Meta information (anything that's NOT a field, such as {{{ordering}}}, {{{admin}}}, {{{unique_together}}}, etc.) now goes in an inner class, called {{{META}}} (note the all caps). This class doesn't have a parent class.
	9	* To manually specify a field's database column name, use {{{db_column}}} as an argument to {{{*Field()}}}.
9	10	* Each field is required to have an explicit name -- even {{{ForeignKey}}}s, {{{ManyToManyField}}}s and {{{OneToOneFields}}}. This solves the problem of "How do I refer to my field from within admin.fields?"
10	11	* {{{rel_name}}} is no longer used for {{{ForeignKey}}}s. If your model has more than one {{{ForeignKey}}} to the same foreign model, differentiate the fields using the field name, not {{{rel_name}}}. See [http://www.djangoproject.com/documentation/models/m2o_recursive2/ Relating a model to another model more than once] for an example.
