* Redesign of the accounting system (quotaholder) and integration into
astakos.

  * Simplified the quotaholder model; removed tables Entity and Policy; now
    table Holding contains limit and usage for every holding.

  * Extended table Holding, so that we can keep track of quota for every
    valid combination of holder (e.g. user), resource, and source (e.g. the
    default system or some specific project).

  * Refactored code for issuing and resolving commissions for robustness;
    added a 'force' option to bypass the upper limit check when issuing a
    commission.

  * Simplified syncing to the quotaholder; removed fields from models
    Project and ProjectMembership, previously needed for syncing; removed
    state PROJECT_DEACTIVATED from ProjectMembership.

* Service and resource specification and handling:

  * Specified a format for defining resources a service exposes. Migrated
    internal resource name by prefixing it with service name (e.g. 'vm'
    becomes 'cyclades.vm'); renamed registered service 'pithos+' to
    'pithos'.

  * Specified a procedure to register a service's resources in astakos and
    set their respective default base quota limit. Removed resource
    definitions from settings.

  * Moved service and resource presentation data out of the respective db
    models into a separate file of UI constants.

* Converted the limit on pending applications from a setting to a quotable
  resource. Converted the related user setting to a user-specific base quota
  limit. Deprecated model UserSetting; removed setting
  ASTAKOS_PENDING_APPLICATION_LIMIT.

* Changes in locking strategy:

  * Lock only project's chain for all project operations; lock user before
    syncing to quotaholder.

  * When locking multiple rows (e.g. users or holdings) include an ORDER BY
    clause in the query to impose ordering on locking.

* API-related changes:

 * Implemented API calls for quota, resources, and commissions.

 * Moved all API calls under '/astakos/api'. Kept also previous locations
   for backwards compatibility.

* Changes in views:

  * Replaced custom transaction context with a simple decorator for managing
    transactions and a context 'ExceptionHandler', which logs and suppresses
    exceptions

* Management commands:

  * Renamed command astakos-quota to quota; user-update to user-modify.

  * Removed user-set-initial-quota; integrated its functionality in
    user-modify and quota.

  * Added quota and project-related information in user-show command; added
    membership information in project-show.

  'reconcile-commissions-cyclades'.
108 109 110
* Remove obsolete 'MAX_VMS_PER_USER', 'MAX_NETWORKS_PER_USER',
  "VMS_USER_QUOTA" and "NETWORKS_USER_QUOTA" settings, since their usage

In v0.13 the code was very heavily refactored for increased uniformity since
most of the Synnefo components have been merged into a single repository. Thus,
**just for this version** we will not document a complete Changelog (features,
fixes, improvements, issues, setting changes), but rather just copy from the
`NEWS` file with minor additions wherever needed.
