Release Notes
*************

Internal changes
================

* The agent source is now organized as a "opensvc" python package.
* The om commands can be run using ``python -m opensvc <args>``.
* The daemon is launched using ``python -m opensvc.daemon``.
* Support out-of-tree drivers. They are looked up in a ``site-opensvc`` package installed in ``sys.path``.
* ``status.json`` and object configuration files are no long overwriten (write in a tempfile and atomic rename).
* Provisioning code is now merged in the resource drivers, instead of in a separate file.
* Move the resource drivers keyword definitions to the driver file.
* On object build, prepare resource driver class arguments using only the keyword dictionnary.
* Use pytest instead of nose for unit testing.
* Discover available API handlers instead of hardcoding the list.
* Allow drivers to register their own api handlers.

Policy changes
==============

* Python 2.6 is no longer supported as an interpreter.
* Set pr status to n/a instead of undef when the resource handles no disks.
* Report n/a for disk.raw devices with no evaluated devs.
* Serialize volume creation cluster-wide.
