2.3.0
^^^^^


New Features
************

* Add new configuration option "rbd_thin_provisioning" and
  "filesystem_thin_provisioning" to rbd and filesystem store to enable
  or not sparse upload, default are False.

  A sparse file means that we do not actually write null byte
  sequences but only the data itself at a given offset, the "holes"
  which can appear will automatically be interpreted by the storage
  backend as null bytes, and do not really consume your storage.

  Enabling this feature will also speed up image upload and save
  network traffic in addition to save space in the backend, as null
  bytes sequences are not sent over the network.

* Added support for cinder multiple stores. Operators can now
  configure multiple cinder stores by configuring a unique
  cinder_volume_type for each cinder store.


Upgrade Notes
*************

* Legacy images will be moved to specific stores as per their
  current volume's type and the location URL will be updated
  respectively.
