0.4.0 - 2011-08-12
Server:
  * deltacloudd: new option --drivers to list all drivers
  * deltacloudd: new options --ssl, --ssl-key and --ssl-cert to
    enable HTTPS support
  * API entrypoint reports features in JSON
  * unify response behavior: any operation returning a 201 Created also
    sets the Location header to point to the new resource; ensure the
    status for an operation is the same regardless of output format
  * Add type to public addresses; type can be one of 'ipv4', 'mac', 'vnc',
    and 'hostname'
  * Complete overhaul of the HTML UI, now uses jquery-mobile
  * Response status for attach/detach storage is now 202 (instead of 302)
  * Response status for get/set blob metadata is 204 No Content
  * Response status for (un)register with load balancer is 204 No Content
  * The user_name feature now reports the permissible length of the name
    as the 'max_length' constraint
  * Add Date header to responses as per RFC 2616
  * New collection 'firewalls' for managing sets of firewalling rules
  * split server/config/drivers.yaml into individual files so each driver
    can be packaged separately; gives deployers better choice of what
    drivers they want enabled
  * Numerous bug fixes and improvements to the test suite
  * Drivers
    + Condor
      - new driver to run a simple cloud based on the Condor grid scheduler
    + EC2
      - Fix bug in reboot instance so that the details returned are those
        of the stopped instance, not some random instance
      - Support getting and updating blob metadata
      - support destroying images
      - support firewalls (security groups)
      - do not support user_name anymore; instance tagging is too fragile
        in EC2 to be used reliably for this
      - do not support registering an instance with a load balancer upon
        creation anymore
      - stream blob PUT to backend (requires thin)
      - support attaching EBS snapshot to instance upon creation (feature
        'attach_snapshot')
      - support elastic IP's
    + Eucalyptus
      - support firewalls (security groups)
      - support elastic IP's
    + Gogrid
      - when retrieving single realm, make sure we return the right one
      - correctly capture load_balancer params
      - report a listener if load_balancer has no instances
    + Mock
      - support destroying images
    + Rackspace
      - support destroying images
      - stream blob PUT to backend (requires thin)
    + RHEV-M
      - support creating and destroying images
      - report VNC address of instances
      - can use Audrey's confserver to fetch IP of an instance
    + vSphere
      - turns a VMWare vSphere installation into a cloud
      - driver stateless, state is stored in vSphere's data store in
        'deltacloud' folder
      - images are template VM's
      - single HWP, whose max_cpu and max_memory are based on available
        cpus and memory across all vSphere hosts
      - support data injection via user_data and user_iso (upload entire
        ISO image) For both, instance gets virtual CD-ROM with injected
        data

Client:
  * make authentication info for instances available
  * retrieve type and address for public addresses of an instance
  * deltacloudc: allow specifying bucket location when creating a bucket

Site:
  * Major rewrite of REST API docs, covers the entire API now
  * Add libdeltacloud API docs

0.3.0 - 2011-04-01
Server:
  * Dynamic driver switching: select driver on a per-request basis; new
    toplevel 'drivers' collection describing drivers supported by server
  * Create images from running instances (EC2, Mock, GoGrid, Rackspace);
    advertised as action 'create_image' in instance details when possible
  * New 'user_files' feature for create_instance to advertise RAX-style
    injection of user data
  * Return status 204 after successful DELETE operation
  * Return status 401 when authentication fails because of invalid
    credentials
  * Blobs: support user metadata as key/value pairs passed through
    X-Deltacloud-Blobmeta-KEY: VALUE headers
  * Support HEAD requests to retrieve the operations and methods supported
    by a collection
  * Support for OPTIONS request to retrieve optional and required
    parameters for operations
  * Advertise 'create_instance' action for each image
  * Drivers
    + EC2
      - instance_count feature to allow creating multiple instances at once
      - run commands inside an insance via ssh
      - by default, list images owned by 'amazon', when passing in empty
        owner_id, list _all_ images (thousands)
    + Eucalyptus
      - new driver for Eucalyptus (Sang-Min Park)
    + Gogrid
      - run commands inside an insance via ssh
      - allow creating sandbox instances
    + Rackspace
      - report root password after instance creation
    + SBC
      - new driver for IBM SBC cloud (Eric Woods)

Client:
  * run: new method to run commands via ssh
