24828	AlterUniqueTogether prevents squashmigrations optimizations	Piotr Maliński	Markus Holtermann	I have a model that has a AlterUniqueTogether so in initial migration after CreateModel there was a AlterUniqueTogether operation. After that I got some migrations that add/alter/remove some fields to that model (but not those in AlterUniqueTogether). squashmigrations couldn't optimize those additional operations into one CreateModel operation. When I moved AlterUniqueTogether to the end of the squash operations list and resquashed then it did that.
