Log Message:
Changes 1.9.5:
Made MultiPartParser ignore filenames that normalize to an empty string to fix \ 
crash in MemoryFileUploadHandler on specially crafted user input.
Fixed a race condition in BaseCache.get_or_set(). It now returns the default \ 
value instead of False if there’s an error when trying to add the value to \ 
the cache.
Fixed data loss on SQLite where DurationField values with fractional seconds \ 
could be saved as None.
The forms in contrib.auth no longer strip trailing and leading whitespace from \ 
the password fields. The change requires users who set their password to \ 
something with such whitespace after a site updated to Django 1.9 to reset their \ 
password. It provides backwards-compatibility for earlier versions of Django.
Fixed a memory leak in the cached template loader.
Fixed a regression that caused collectstatic --clear to fail if the storage \ 
doesn’t implement path().
Fixed a crash when using a reverse lookup with a subquery when a ForeignKey has \ 
a to_field set to something other than the primary key.
Fixed a regression in CommonMiddleware that caused spurious warnings in logs on \ 
requests missing a trailing slash.
Restored the functionality of the admin’s raw_id_fields in list_editable.
Fixed a regression with abstract model inheritance and explicit parent links.
Fixed a migrations crash on SQLite when renaming the primary key of a model \ 
containing a ForeignKey to 'self'.
Fixed JSONField inadvertently escaping its contents when displaying values after \ 
failed form validation.
