+## 0.10.0 - 2019-01-14
+
+### Added
+
+- The installer pushes an Infrastructure object to
+ infrastructures.config.openshift.io with platform information.
+ Cluster components should use this instead of the deprecated
+ `cluster-config-v1` resource.
+- `openshift-install` has a new `completion` subcommand, to generation
+ shell-completion code (currently only for Bash).
+- On AWS, `destroy cluster` now also removed IAM users with the usual
+ tags. We don't create these users yet, but the removal sets the
+ stage for the coming credentials operator.
+
+### Changed
+
+- Install configuration now includes a new `apiVersion` property which
+ must be set to `v1beta1`. Future changes to the install-config
+ schema will result in new versions, allowing new installers to
+ continue to support older install-config schema (and older
+ installers to error out when presented with newer install-config
+ schema). Changes to the schema since 0.9.0:
+
+ - `clusterID` has been removed. This should be a new UUID for
+ every cluster, so there is no longer an easy way for users to
+ configure it.
+ - Image configuration has been removed. Almost all users should
+ be fine with the installer-chosen RHCOS. Users who need to
+ override the RHCOS build (because they're testing new RHCOS
+ releases) can set a new `OPENSHIFT_INSTALL_OS_IMAGE_OVERRIDE`
+ environment variable.
+ - Per-platform network properties have been consolidated into the
+ platform-agnostic `machineCIDR` from which node IP addresses are
+ assigned.
+ - On libvirt, all machine-pool configuration has been removed, as
+ no remaining properties were supported by the libvirt
+ cluster-API provider.
+
+- `install-config.yaml` read during [staged
+ installs](docs/user/overview.md#multiple-invocations) will now have
+ installer-defaults applied for missing properties. This allows you
+ to set only the properties you are interested in overriding, and
+ allow the installer to manage the remaining properties.
+- `create ignition-configs` now also writes the admin kubeconfig to
+ the asset directory, to support bring-your-own-infrastructure use
+ cases.
+- The bootstrap node now [serves
+ journals](docs/user/troubleshooting.md#troubleshooting-the-bootstrap-node)
+ for easier troubleshooting.
+- The validity for the initial kubelet TLS certificate has been
+ increased from one hour to 24 hours, to give
+ bring-your-own-infrastructure users longer to manually distribute
+ the certificate before it expires.
+- The key for the root certificate authority is no longer pushed into
+ the cluster (not even to the bootstrap node).
+- Machine(set)s generated by the installer now use `providerSpec`
+ instead of the deprecated `providerConfig`.
+- On AWS, the load balancers now use HTTPS health checks to reduce log
+ noise like:
+
+  http: TLS handshake error from 10.0.20.86:28372: EOF
+
+- On AWS, IAM roles are now tagged with the usual resource tags
+ (`openshiftClusterID`, etc.). Some other resources have had their
+ tags updated to match those conventions (e.g. the internal Route 53
+ hosted zone was updated from `KubernetesCluster` to
+ `kubernetes.io/cluster/{name}: owned`).
+- The OpenStack platform has been removed from the install-config
+ wizard while it remains experimental. It is still available for
+ users who supply their own `install-config.yaml`.
+- On OpenStack, the service VP now respects any SSH key specified in
+ the install configuration.
+- On OpenStack, a developer-only internal DNS server has been removed,
+ so users need to configure additional records for the existing
+ external DNS zone.
+- On OpenStack, Neutron trunk ports are now used for VM network
+ interfaces if Neutron supports them to support future Kuryr
+ integration.
+- On OpenStack, masters and workers have been consolidated in a single
+ subnet to simplify the deployment.
+- On OpenStack, the Ignition security group now only allows internal
+ connections, and no longer allows connections from outside the
+ cluster network.
+- On OpenStack, the machine(set) templates have been updated to set
+ `cloudName` and some other properties.
+- On libvirt, `destroy cluster` is not more robust in the face of
+ domains which were already shutdown.
+- Lots of doc and internal cleanup and minor fixes.
+
+### Removed
+
+- Support for `install-config.yml` (deprecated in 0.8.0) has been
+ removed.
+
+### Fixed
+
+- On AWS, domain pagination for the wizard's base-domain select widget
+ has been fixed. Previously, it would continuously fetch the first
+ page of hosted zones (for accounts with multiple pages of zones)
+ until it hit an error like:
+
+ ```
+ ERROR list hosted zones: Throttling: Rate exceeded
+ status code: 400, request id: ...
+ ```
+
+ before falling back to a free-form base domain input.
