This enhancement adds support for configuring multiple IPv6 prefixes and addresses on a single interface.
As a result, OpenStack Networking (neutron) considers the type of IPv6 subnets that form part of the network, and automatically associates ports with addresses from all the SLAAC-enabled subnets within the ports network.
There is no change to the REST API, but port-create/port-update responses automatically include the SLAAC addresses in the list of 'fixed_ips'.

Compute can now provide dedicated CPU resources, where each guest virtual CPU has full access to a specific host CPU.
Previous releases of Compute guest CPUswere permitted to float across any host CPU. Even when the NUMA feature was enabled, the CPUs could still float within a NUMA node. Host CPUs would  also overcommit so many virtual CPUs contended for the host resource. This made it impossible to provide strong performance guarantees to guest operating system workloads.
With this update, the cloud administrator now has the ability to set up a host aggregate, which provides a pool of hosts that supports guests with dedicated CPU resource assignment. The cloud administrator or tenant user can make use of these pools to run instances with guaranteed CPU resource.

The 'API Access' page in the dashboard ('Project > Compute > Access & Security > API Access') now provides more information on user credentials. To view this information, click 'View Credentials'. A pop-up displays the user name, project name, project ID, authentication URL, S3 URL, EC2 URL, EC2 access, and secret key.

The option to create Block Storage (cinder) volume transfers has been added to the 'Volumes' tab in the OpenStack dashboard. Volume transfers move ownership from one project to another. A donor creates a volume transfer, captures the resulting transfer ID and secret authentication key, and passes that information out of band to the recipient (such as by email or text message). The recipient accepts the transfer, supplying the transfer ID and authentication key. The ownership of the volume is then transferred from the donor to the recipient, and the volume is no longer visible to the donor.

Note the following limitations of the Block Storage API for volume transfers and their impact on the UI design:
1. When creating a volume transfer, you cannot specify who the intended recipient will be, and anyone with the transfer ID and authentication key can claim the volume. Therefore, the dashboard UI does not prompt for a recipient.
2. Current volume transfers are only visible to the donor; users in other projects are unable to view these transfers. So, the UI does not include a project table to view and accept volume transfers, since the current transfers are not visible. Instead, the transfer information is added to the volume details, which are visible by the donor, and the volume state clearly reflects that a transfer has been created. The UI also cannot present to the recipient a pull-down list of transfers to accept.
3. The only time that the authorization key is visible to the donor is in the response from the creation of the transfer; after creation, it is impossible for even the donor to recover it. Since the donor must capture the transfer ID and authorization key in order to send it to the recipient, an extra form was created to present this information to the donor immediately after the transfer has been created.

Identity Service (keystone) now allows for unscoped tokens to be explicitly requested.
This feature was added after users who had a default project assigned were previously unable to retrieve unscoped tokens; if one of these users requested a token without defining a scope, it would be automatically scoped to the default project.
As a result of this update, unscoped tokens can now be issued to all users, even if they have a default project defined.

"cluster_configs": {
   "HDFSHA": {
      "hdfs.nnha": true
   }
}

With this update, administrators are now able to view the state of High Availability routers on each node, and specifically, where the active instance is hosted. 
Previously, the High Availability router state information was not visible to the administrator; this made maintenance harder, for example, when moving HA router instances from one agent to another, or assessing the impact of putting a node in maintenance mode. 
This new functionality also serves as a sanity test and offers assurance that a router is indeed active on only one node. As a result, administrators may now run the 'neutron l3-agent-list-hosting-router <router_id>' command on a High Availability router to view where the active instance is currently hosted.

Previously, Image service's 'swift' store implementation stored all images on a single container. While this worked well, it created a performance bottleneck in large scale deployments.

With this update, it is now possible to use several Object Storage containers as storage for the 'glance' images. In order to use this feature, you need to set 'swift_store_multiple_containers_seed' to a value bigger than '0'. You can disable using multiple containers by enabling the 'swift_uer_multi_tenant' parameter, as these containers are split on a per-tenant basis.

Previously, the cm_api library was not packaged by Cloudera for any Linux distribution. The previous CDH plug-in depended on this package, so CDH could not be enabled as a default plug-in prior to this release. Now, a subset of the cm_api library has been added to Sahara's codebase, and CDH is functional and enabled by default.

The Identity service now allows unscoped federation tokens to be used to obtain a scoped token using the 'token' authentication method.

When using the Identity service's federation extension, an unscoped federation token is returned as a result of the initial authentication. This is then exchanged for a scoped token. An unscoped federation token previously had to use the 'saml2' or 'mapped' authentication to obtain a scoped token. This is inconsistent with the method used to exchanging a regular unscoped token for a scoped token, which uses the 'token' method.

Exchanging an unscoped federation token for a scoped token now uses the 'token' authentication method, which is consistent with the regular unscoped token behavior.

The Identity service now allows restriction of re-scoping tokens to only allow unscoped changes to be exchanged for scoped tokens.

The Identity service allows for an existing token to be used to obtain a new token via the 'token' authentication method.  Previously, a user with a valid token scoped for a project could use that token to obtain another token for a different project that they were authorized for.  This allowed for anyone possessing a user's token to have access to any project the user has access to, as opposed to only having access to the project that the token is scoped for.  To improve the security properties of scoped tokens, it was desirable to not allow this.
 
A new 'allow_rescope_scoped_token' configuration option is available to allow token rescoping to be retricted. Rescoping of tokens is now only allowed by using an unscoped token to authenticate when this option is enabled.

Previously, every call to policy.enforce passed an empty dictionary as the target. This prevented operators from using tenant specific restrictions in their policy.json files since the target would always be an empty dictionary. If you tried to restrict some actions so an image owner (users with the correct tenant id) could perform actions, the check categorically failed because the target is okay is an empty dictionary.

With this update, you can pass the ImageTarget instance wrapping an Image to the enforcer so these rules can be used and properly enforced. You can now properly grant access to the image owner(s) based on tenant (e.g., owner:%(tenant)). Without this fix, the only check that actually works in Image service is a RoleCheck (e.g., role:admin).

Support has been added for intelligent NUMA node placement for guests that have been assigned a host PCI device. PCI I/O devices, such as  Network Interface Cards (NICs), can be more closely associated with one processor than another. This is important because there are different memory performance and latency characteristics when accessing memory directly attached to one processor than when accessing memory directly attached to another processor in the same server. With this update, Openstack guest placement can be optimized by ensuring that a guest bound to a PCI device is scheduled to run on a NUMA node that is associated with the guest's pCPU and memory allocation. For example, if a guest's resource requirements fit in a single NUMA node, all guest resources will now be associated with the same NUMA node.

The Identity service now has an experimental support for a new token format called 'fernet'.

The token formats currently supported by the Identity service require issued tokens to be persisted in a database table. This table can grow quite large, which requires proper tuning and a flush job to keep the Identity service performing well. The new 'fernet' token format is designed to allow the token database table to be eliminated, avoiding the problem of this table becoming a scalability limitation. The 'fernet' token format is now available as an experimental feature.

All Ironic drivers now support deployment via IPA ramdisk. IPA is written in Python, supports more features than the BASH ramdisk, and runs as a service. For these reasons, nodes deployed through IPA are generally easier to deploy, debug, and manage.

With this update, it is now possible to filter the list operations by more than one filter option and in multiple directions. For example:

  /images?sort=status:asc,name:asc,created_at:desc

With the above, a list of images will be returned and they will be sorted by status, name, and creation date with the following directions respectively: ascending, ascending, and descending.

Imbalance in tiers in Swift was previously addressed by weights. However, no matter what the numerical ratio of weight is set, at a certain point there are not enough devices and replicas remaining in lower weight tiers to balance out the crowding at the higher weight tier. At this moment, the tier becomes underutilized, while an administrator may need to force more than one replica into tier to achieve utilization. The ratio of more-than-1 partition is the overload parameter.

This update permits administrators to store more than one replica in a tier in case of severely unbalanced clusters. As a result, it is now possible so sacrifice data durability in order to achieve better utilization, which in some cases is required for availability. For example, a cluster will fail to store new data if low-weight tiers overflow and quorum fails.

Previously, the GUI did not allow a user to create or upload images.

This new feature adds the following changes to the horizon and the tuskar-ui packages. To horizon, it adds the Kernel and Ramdisk fields to the create image form in horizon, which enables a user to associate a kernel and a ramdisk to a glance image during image creation. In the tuskar-ui, it exposes horizon's create image form (with the newly added capability to set kernel and ramdisk) in the tuskar-ui. On the images page, there should now be a "create image" button which allows the user to create an image. As a result, GUI now has the ability to create images.

Previously, when using huge pages, the back-end memory for a guest was configured as private. Consequently, the vhostuser VIF back end was designed to allow an external process to provide the QEMU network driver functionality. For some use cases of vhostuser, this required that the external process be able to access the QEMU guest's memory pages directly. This is not possible when the huge pages are mapped with MAP_PRIVATE; they must use MAP_SHARED instead. With this update, when a guest is configured to use huge pages backed memory, mappings are be marked as shared. As a result, the external process to provide QEMU network is now able to access to guest's memory pages.

On a PATCH update (using the "-x" flag in the 'heat stack-update' command), the existing environment is now retained unless explicitly overridden. This is because the Orchestration service now re-uses other parts of the environment, not just the parameters that were passed previously and not overriden.

This feature was added because in the most common stack update cases, users prefer to maintain the current environment (including resource mappings and the like). This will also prevent any unintended changes in complex deployments whenever users forget to include the required environment files at stack creation time.
