* Added ``datetime.time`` support to migrations questioner (:ticket:`23998`).
* Fixed admindocs crash on apps installed as eggs (:ticket:`23525`).
* Changed migrations autodetector to generate an ``AlterModelOptions`` operation
instead of ``DeleteModel`` and ``CreateModel`` operations when changing
``Meta.managed``. This prevents data loss when changing ``managed`` from
``False`` to ``True`` and vice versa (:ticket:`24037`).
