REST API Version History
========================

This documents the changes made to the REST API with every
microversion change. The description for each version should be a
verbose one which has enough information to be suitable for use in
user documentation.

1.0 (Maximum in Kilo)
---------------------
  The 1.0 Manila API included all v1 core APIs existing prior to
  the introduction of microversions.  The /v1 URL was used to call
  1.0 APIs, and microversions headers sent to this endpoint were
  ignored.

  .. note::

     The v1 API was removed in the 2026.1 (Gazpacho) release.

2.0
---
  This is the initial version of the Manila API which supports
  microversions.  The /v2 URL is used to call 2.x APIs.

  A user can specify a header in the API request::

    X-OpenStack-Manila-API-Version: <version>

  where ``<version>`` is any valid api version for this API.

  If no version is specified then the API will behave as if version 2.0
  was requested.

  The only API change in version 2.0 is versions, i.e.
  GET http://localhost:8786/, which now returns information about
  both 1.0 and 2.x versions and their respective /v1 and /v2 endpoints.

  All other 2.0 APIs are functionally identical to version 1.0.

2.1
---
  Share create() method doesn't ignore availability_zone field of provided
  share.

2.2
---
  Snapshots become optional and share payload now has
  boolean attr 'snapshot_support'.

2.3
---
  Share instances admin API and update of Admin Actions extension.

2.4
---
  Consistency groups support. /consistency-groups and /cgsnapshots are
  implemented. AdminActions 'os-force_delete and' 'os-reset_status' have been
  updated for both new resources.

2.5
---
  Share Migration admin API.

2.6 (Maximum in Liberty)
------------------------
  Return share_type UUID instead of name in Share API and add share_type_name
  field.

2.7
---
  Rename old extension-like API URLs to core-API-like.

2.8
---
  Allow to set share visibility explicitly using "manage" API.

2.9
---
  Add export locations API. Remove export locations from "shares" and
  "share instances" APIs.

2.10
----
  Field 'access_rules_status' was added to shares and share instances.

2.11
----
  Share Replication support added. All Share replication APIs are tagged
  'Experimental'. Share APIs return two new attributes: 'has_replicas' and
  'replication_type'. Share instance APIs return a new attribute,
  'replica_state'.

2.12
----
  Share snapshot manage and unmanage API.

2.13
----
  Add 'cephx' authentication type for the CephFS Native driver.

2.14
----
  Added attribute 'preferred' to export locations.  Drivers may use this
  field to identify which export locations are most efficient and should be
  used preferentially by clients.  Also, change 'uuid' field to 'id', move
  timestamps to detail view, and return all non-admin fields to users.

2.15 (Maximum in Mitaka)
------------------------
  Added Share migration 'migration_cancel', 'migration_get_progress',
  'migration_complete' APIs, renamed 'migrate_share' to 'migration_start' and
  added notify parameter to 'migration_start'.

2.16
----
  Add user_id in share show/create/manage API.

2.17
----
  Added user_id and project_id in snapshot show/create/manage APIs.

2.18
----
  Add gateway in share network show API.

2.19

  Add admin APIs(list/show/detail/reset-status) of snapshot instances.

2.20
----
  Add MTU in share network show API.

2.21
----
  Add access_key in access_list API.

2.22 (Maximum in Newton)
------------------------
  Updated migration_start API with 'preserve_metadata', 'writable',
  'nondisruptive' and 'new_share_network_id' parameters, renamed
  'force_host_copy' to 'force_host_assisted_migration', removed 'notify'
  parameter and removed previous migrate_share API support. Updated
  reset_task_state API to accept 'None' value.

2.23
----
  Added share_type to filter results of scheduler-stats/pools API.

2.24
----
  Added optional create_share_from_snapshot_support extra spec. Made
  snapshot_support extra spec optional.

2.25
----
  Added quota-show detail API.

2.26
----
  Removed nova-net plugin support and removed 'nova_net_id' parameter from
  share_network API.

2.27
----
  Added share revert to snapshot. This API reverts a share to the specified
  snapshot. The share is reverted in place, and the snapshot must be the most
  recent one known to manila. The feature is controlled by a new standard
  optional extra spec, revert_to_snapshot_support.

2.28
----
  Added transitional states ('queued_to_apply' - was previously 'new',
  'queued_to_deny', 'applying' and 'denying') to access rules.
  'updating', 'updating_multiple' and 'out_of_sync' are no longer valid
  values for the 'access_rules_status' field of shares, they have
  been collapsed into the transitional state 'syncing'. Access rule changes
  can be made independent of a share's 'access_rules_status'.

2.29
----
  Updated migration_start API adding mandatory parameter 'preserve_snapshots'
  and changed 'preserve_metadata', 'writable', 'nondisruptive' to be mandatory
  as well. All previous migration_start APIs prior to this microversion are now
  unsupported.

2.46 (Maximum in Rocky)
-----------------------
  Added 'is_default' field to 'share_type' and 'share_group_type'
  objects.

2.47
----
  Export locations for non-active share replicas are no longer retrievable
  through the export locations APIs: ``GET
  /v2/{tenant_id}/shares/{share_id}/export_locations`` and ``GET
  /v2/{tenant_id}/shares/{share_id}/export_locations/{export_location_id}``.
  A new API is introduced at this version: ``GET
  /v2/{tenant_id}/share-replicas/{replica_id}/export-locations`` to allow
  retrieving export locations of share replicas if available.

2.48
----
  Administrators can now use the common, user-visible extra-spec
  'availability_zones' within share types to allow provisioning of shares
  only within specific availability zones. The extra-spec allows using
  comma separated names of one or more availability zones.

2.49 (Maximum in Stein)
-----------------------
  Added Manage/Unmanage Share Server APIs. Updated Manage/Unmanage Shares and
  Snapshots APIs to work in ``driver_handles_shares_servers`` enabled mode.

  ``description`` and/or ``share_type_access:is_public`` fields of the share
  type by the update share type API.

2.51 (Maximum in Train)
-----------------------
  Added to the service the possibility to have multiple subnets per share
  network, each of them associated to a different AZ. It is also possible to
  configure a default subnet that spans all availability zones.

  a share server and all its resources to a new host.

2.58
----

2.59
----
  Added 'details' field to migration get progress api, which optionally may hold
  additional driver data related to the progress of share migration.

2.60
----
  API URLs no longer need a "project_id" argument in them. For example, the
  API route: https://$(controller)s/share/v2/$(project_id)s/shares is
  equivalent to https://$(controller)s/share/v2/shares. When interacting
  with the manila service as system or domain scoped users, project_id should
  not be specified in the API path.

2.61
----
  Ability to add minimum and maximum share size restrictions which
  can be set on a per share-type granularity. Added new extra specs
  'provisioning:max_share_size' and 'provisioning:min_share_size'.

  Also, an attached security service can be replaced for another one of
  the same 'type'. In order to support those operations a 'status' field was
  added in the share networks as well as, a new property called
  'security_service_update_support' was included in the share networks and
  share servers. Also new action APIs have been added to the share-networks
  endpoint: 'update_security_service', 'update_security_service_check' and
  'add_security_service_check'.

  without go through share scheduler.

----
  Added filter search by group spec for share group type list.

2.67
----
  Added support for 'only_host' key in "scheduler_hints" in the request body
  of the POST/shares and POST/share-replicas request. This hint will invoke
  'OnlyHost' scheduler filter during share and share-replica creation.

2.68
----
  Added admin only capabilities to share metadata API.

2.69
----
  Manila support Recycle Bin. Soft delete share to Recycle Bin: ``POST
  /v2/shares/{share_id}/action  {"soft_delete": null}``. List shares in
  Recycle Bin: `` GET /v2/shares?is_soft_deleted=true``. Restore share from
  Recycle Bin: `` POST /v2/shares/{share_id}/action  {'restore': null}``.

2.70 (Maximum in Yoga)
----------------------
  Added support to configure multiple subnets for a given share network in the
  same availability zone (or the default one). Users can also add new subnets
  for an in-use share network. To distinguish this update support a new
  property called 'network_allocation_update_support' was added in the share
  network and share server.
