[PATCH 2/5] templates: Resolve cycle issues with Django 1.10

Stephen Finucane stephen at that.guru
Mon Oct 10 09:26:39 AEDT 2016


The 'future.cycle' template tag is removed in Django 1.10. Since
Django 1.7 is still supported by Patchwork, it is necessary to
provide a custom 'cycle' wrapper to prevent the deprecation
warnings resolved by '9cab078' being reintroduced.
