v1.3 - 2013-02-10

• IMPORTANT: The file extension for include files is now .php (instead of
  .inc). This came at the request of numerous individuals. However, it means
  that all of your scripts that use php-opencloud must be edited.
• DataObject::Create() now uses content_type; using the older
  type parameter is deprecated and will cause an UnknownParameterError
  exception.
• New global constant RAXSDK_CACERTPEM; if defined, this should be a path
  to a cacert.pem file that defines the root certificate servers. Defining
  this provides an extra degree of security in the HTTP transfer operations.
• Fixed a bug (issue #25) wherein the entire DataObject was retrieved in the
  constructor. This was incorrect; the constructor now does a HEAD request,
  and you need to use the SaveToFilename() or SaveToString() methods to
  actually fetch the data from Swift/Cloud Files. If your code relies upon
  the previous behavior, this might cause it to break.
• Support for Rackspace Cloud Load Balancers
• Fix to remove requirement for Tenant ID in authentication
• Added ExportCredentials() and ImportCredentials() methods to the
  OpenStack class to permit caching of tokens.
