Subject [ANNOUNCE] Apache Deltacloud 0.3.0 (incubating)
Date Thu, 28 Apr 2011 23:00:37 GMT
I am pleased to announce the availability of Apache Deltacloud 0.3.0.

Apache Deltacloud is a RESTful cloud abstraction API. The release
consists both of the API server and a Ruby client.

The release can be found at Gems and RPM's

Overview of the changes for this release:

  * 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
  * 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
