 In 2007, Peru changed from departments to regions for their local district names. In [8230], Django's Peruvian localflavor was updated to reflect this change. Previous uses of the `PEDepartmentSelect` class (from `django.contrib.localflavor.pe.forms`) should be changed to use `PERegionSelect`.

+[8244] refactored Django's file storage system. Detailed notes of the changes can be found at FileStorageRefactor; see specifically the [http://code.djangoproject.com/wiki/FileStorageRefactor#Backwards-incompatibilechanges list of backwards-incompatibe changes].

+{{{
+#!python
+class FileContent(models.Model):
+    content = models.FileField(upload_to='content')
+}}}
