<commit_before>## v0.9.9 (in development)

### New features & improvements:

- System check for deferred builtin which should always be switched off.
-

### Bug fixes:

- Fixed a minor bug where entities were still added to memcache (but not fetched from it) with `DJANGAE_CACHE_ENABLED=False`.  This fix now allows disabling the cache to be a successful workaround for https://code.google.com/p/googleappengine/issues/detail?id=7876.
- Fixed a bug where entities could still be fetched from memcache with `DJANGAE_CACHE_ENABLED=False` when saving in a transaction or deleting them.
- Fixed overlap filtering on RelatedListField and RelatedSetField (Thanks Grzes!)
- Fixed various issues with `djangae.contrib.mappers.defer_iteration`, so that it no longers gets stuck deferring tasks or hitting memory limit errors when uses on large querysets.
- Fixed reverse lookups with the SimulatedContentTypesManager
- Fixed validation problems when using simulated contenttypes when IDs would be too large for an AutoField
