For other SDKs, see

The PHP SDK should work with most OpenStack-based cloud deployments, though it specifically targets the Rackspace public cloud. In general, whenever a Rackspace deployment is substantially different than a pure OpenStack one, a separate Rackspace subclass is provided so that you can still use the SDK with a pure OpenStack instance (for example, see the OpenStack class (for OpenStack) and the Rackspace subclass).

See the Release Notes for what has changed in the latest release(s).

See the php-opencloud wiki for incidental notes mostly aimed at developers who are working on the SDK (and not developers working with the SDK).
