django-batch-select (via) A smart attempt at solving select_related for many-to-many relationships in Django. Add a custom manager to your model and call e.g. Entry.objects.all()[:10].batch_select("tags") to execute two queries - one pulling back the first ten entries and another using an "IN" query against the tags table to pull back all of the tags for those entries in one go.

Extra fields on many-to-many relationships (via) Checked in just over an hour ago, Django now lets you specify a custom “through” table for a ManyToManyField. Great work by Eric Florenzano.
