0.43.0

Fixed a bug with MediaStorage.delete_unused_files - it was raising an exception when used with Array columns. Thanks to @sumitsharansatsangi for reporting this issue.

When using S3MediaStorage you can now specify additional arguments when files are uploaded (using the upload_metadata argument), for example, setting the cache settings, and much more. Thanks to @sumitsharansatsangi, and @sinisaos for help reviewing.

S3MediaStorage(
    ...,
    # Cache the file for 24 hours:
    upload_metadata={'CacheControl': 'max-age=86400'}
)
