Changes with Apache Libcloud 0.12.3:

  *) General

    - Fix Python 3.x related regressions. (LIBCLOUD-245)
      Reported by Arfrever Frehtes Taifersar Arahesis.
      [Tomaz Muraus]

    - Fix a regression introduced with recent xmlrpiclib changes which broke all
      the Gandi.net drivers. (LIBCLOUD-288)

      Reported by Hutson Betts.
      [Tomaz Muraus]

    - Improve deploy code to work correctly if the ssh user doesn't have access
      to the /root directory.

      Previously the ScriptDeployment script was stored in /root folder by
      default. Now it's stored in users home directory under filename
      ~/libcloud_deploymeny_<random>.sh. (LIBCLOUD-302)

      Reported by rotem on #libcloud.
      [Tomaz Muraus]

  *) Compute

    - Improve public and private IP address handling in OpenStack 1.1 driver.
      Assume every IP address which doesn't have a label "public" or "internet"
      is private. (LIBCLOUD-297)
      [Grischa Meyer, Tomaz Muraus]

    - Add new driver for DigitalOcean provider - https://www.digitalocean.com/.
      (LIBCLOUD-304)
      [Tomaz Muraus]

    - Fix a regression in ParamikoSSHClient.run method which caused this methid
      to only work as expected if you passed an absolute or a relative path to
      the script to it. (LIBCLOUD-278)
      [Tomaz Muraus]

  *) DNS

    - Allow user to specify 'priority' extra argument when creating a MX or SRV
      record.
      [Brian Jinwright, Tomaz Muraus]

Changes with Apache Libcloud 0.12.1:

  *) General

    - Deprecate LazyList method of iteration over large paginated collections
      and use a new, more efficient generator based approach which doesn't
      require the iterator to be pre-exhausted and buffering all of the values
      in memory.

      Existing list_* methods which previously used LazyList class are
      preserving the old behavior and new iterate_* methods which use a new
      generator based approach have been added. (LIBCLOUD-254)
      [Mahendra M]

    - Replace old ENUM style provider constants and replace them with a string
      version.
      This change allows users to dynamically register new drivers using a new
      set_driver method. (LIBCLOUD-255)
      [Mahendra M]

    - Allow user to explicitly specify which CA file is used for verifying
      the server certificate by setting 'SSL_CERT_FILE' environment variable.

      Note: When this variable is specified, the specified path is the only
      CA file which is used to verifying the server certificate. (LIBCLOUD-283)
      [Tomaz Muraus, Erinn Looney-Triggs]

    - Add a common module (libcloud.common.xmlrpc) for handling XML-RPC
      requests using Libcloud http layer.

      Also refactor existing drivers which use xmlrpclib directly (VCL, Gandi,
      Softlayer) to use this module.

      This change allows drivers to support LIBCLOUD_DEBUG and SSL certificate
      validation functionality. Previously they have bypassed Libcloud http
      layer so this functionality was not available. (LIBCLOUD-288)
      [John Carr]

  *) Compute

    - Fix string interpolation bug in __repr__ methods in the IBM SCE driver.
      (LIBCLOUD-242)
      [Tomaz Muraus]

    - Fix test failures which happened in Python 3.3 due to:
      - hash randomization
      - changes in xml.etree module
      - changes in xmlrpc module
      (LIBCLOUD-245)
      [Tomaz Muraus]

    - Improvements and additions in vCloud driver:
      - Expose generic query method (ex_query)
      - Provide functionality to get and set control access for vApps. This way
        created vApps can be shared between users/groups or everyone.
     (LIBCLOUD-251)
     [Michal Galet]

   - Update EC2 pricing data to reflect new, lower prices -

     [Tomaz Muraus]

     - ex_create_security_group, ex_delete_security_group
     - ex_create_security_group_rule, ex_delete_security_group_rule
     (LIBCLOUD-253)
     [L. Schaub]

   - Modify ElasticStack driver class to pass 'vnc auto' instead of
     'vnc:ip auto' argument to the API when creating a server.
     It looks like 'vnc:ip' has been replaced with 'vnc'.

   - Add new EC2 instance type - High Storage Eight Extra Large Instance
     (hs1.8xlarge).
     [Tomaz Muraus]

   - Map 'shutting-down' node state in EC2 driver to UNKNOWN. Previously

     Note: This change is backward incompatible which means you need to update
     your code if you rely on the old behavior.
     [Tomaz Muraus, Marcin Kuzminski]

   - Change _wait_until_running method so it supports waiting on multiple nodes
     and make it public (wait_until_running). (LIBCLOUD-274)

      so it can more easily be re-used with other implementations (e.g. Google
      Storage, etc.).

      Also default to a multipart upload when using upload_object_via_stream.
      This methods is more efficient compared to old approach because it only
      requires buffering a single multipart chunk (5 MB) in memory.
      (LIBCLOUD-269)
      [Mahendra M]

      [Tomaz Muraus]

Changes with Apache Libcloud 0.11.2:

  *) General

    Fix a bug with the Libcloud SSL verification code. Code was too strict and

      [Daemian Mack]

    - Allow user to specify which IP to use when calling deploy_node.

      [Jay Doane]

    - Fix CloudSigmaLvsNodeDriver connectionCls bug.

      [Adam Pickeral]

Changes with Apache Libcloud 0.9.1:

  *) General:

    - Make parsing of the Auth API responses in the OpenStack drivers more
      flexible and extensible.

      Now, every connection class that inherits from the openstack base
      connection must implement get_endpoint(), who's job is to return the
      correct endpoint out of the service catalog.

      Note: The openstack.py base driver no longer works by default with
      Rackspace nova. The default endpoint parsed from the service catalog
      is the default compute endpoint for devstack. (LIBCLOUD-151)
      [Brad Morgan]

    - Allow user to pass ex_tenant_name keyword argument to the OpenStack node
      driver class. This scopes all the endpoints returned by the Auth API
      endpoint to the provided tenant. (LIBCLOUD-172)
      [James E. Blair]

    - Allow user to specify OpenStack service catalog parameters (service type,
      name and region). This way base OpenStack driver can be used with
      different providers without needing to subclass. (LIBCLOUD-173)
      [James E. Blair]

    - Fix a bug with handling compressed responses in the Linode driver.
