General
~~~~~~~

  [Tomaz Muraus]

- Add support for AWS Signature version 4.

  Note: Currently only GET HTTP method is supported.
  (GITHUB-444)

  type and not a str or int.
  (GITHUB-533, LIBCLOUD-716)
  [Avi Weit]

- Update ``is_valid_ip_address`` function so it also works on Windows.
  (GITHUB-343, GITHUB-498, LIBCLOUD-601, LIBCLOUD-686)
  [Nicolas Fraison, Samuel Marks]

- Add support for retrying failed HTTP requests.

  Retrying is off by default and can be enabled by setting

  (GITHUB-515, LIBCLOUD-360, LIBCLOUD-709)

- Fix a bug in consuming stdout and stderr strams in Paramiko SSH client.
  In some cases (like connecting to localhost via SSH), exit_status_ready
  gets set immediately even before the while loop to consume the streams
  kicks in. In those cases, we will not have consumed the streams at all.
  (GITHUB-558)
  [Lakshmi Kannan]

Compute
~~~~~~~

- Google Compute now supports paginated lists including filtering.
  (GITHUB-491)
  [Lee Verberne]

- OpenStackNodeSize objects now support optional, additional fields that are
  supported in OpenStack 2.1: `ephemeral_disk`, `swap`, `extra`.
  (GITHUB-488, LIBCLOUD-682)
  [Greg Hill]

- StorageVolume objects now have an attribute `state` that holds a
  state variable that is standardized state across drivers. Drivers that
  currently support the `state` attribute are OpenStack and EC2.
  StorageVolume objects returned by drivers that do not support the
  attribute will have a `state` of `None`. When a provider returns a state
  that is unknown to the driver, the state will be `UNKNOWN`. Please report
  such states. A couple of drivers already put state fields in the `extra`
  fields of StorageVolumes. These fields were kept for
  backwards-compatibility and for reference.
  (GITHUB-476)
  [Allard Hoeve]

- StorageVolume objects on EC2 and OpenStack now have a key called snapshot_id
  in their extra dicts containing the snapshot ID the volume was based on.
  (GITHUB-479)
  [Allard Hoeve]

- OpenStack driver: deprecated ex_create_snapshot and ex_delete_snapshot in
  favor of create_volume_snapshot and destroy_volume_snapshot. Updated base
  driver method create_storage_volume argument name to be optional.
  (GITHUB-478)
  [Allard Hoeve]

- Add support for creating volumes based on snapshots to EC2 and OS drivers.
  Also modify signature of base NodeDriver.create_volume to reflect the fact
  that all drivers expect a StorageSnapshot object as the snapshot argument.
  (GITHUB-467, LIBCLOUD-672)
  [Allard Hoeve]

- VolumeSnapshots now have a `created` attribute that is a `datetime`
  field showing the creation datetime of the snapshot. The field in
  VolumeSnapshot.extra containing the original string is maintained, so
  this is a backwards-compatible change.
  (GITHUB-473)
  [Allard Hoeve]

- Improve GCE create_node, make sure ex_get_disktype function
  (GITHUB-448)
  [Markos Gogoulos]

- GCE driver fix to handle unknown image projects

  Also allow "name" argument to be empty (None). This way CloudStack
  automatically uses Node's UUID for the name.
  (GITHUB-289)
  [Jeff Moody]

- Deprecate "key" argument in the SSHClient class in favor of new "key_files"
  argument.

  Also add a new "key_material" argument. This argument can contain raw string

  Note #1: If timed out happens, this functionality doesn't guarantee that the
  underlying command will be stopped / killed. The way it works it simply
  closes a connect to the remote server.
