## 0.12.0 - 2019-02-05

### Changed

- We now wait for [`ClusterVersion`][ClusterVersion] to report all
operators as available before returning from `create cluster`.
- We now configure the network operator via
`networks.config.openshift.io` and reserve
`networkconfigs.networkoperator.openshift.io` for lower-level
configuration (although we still generate it as well).
- We now set `apiServerURL` and `etcdDiscoveryDomain` in
`infrastructures.config.openshift.io`.
- Release binaries are now stripped, which dramatically reduces their
size. Builds with `MODE=dev` remain unstripped if you want to
attach a debugger.
- On AWS, `destroy cluster` no longer depends directly on the cluster
name (although it still depends on the cluster name indirectly via
the `kubernetes.io/cluster/{name}` tag). This makes it easier to
reconstruct `metadata.json` for `destroy cluster` if you
accidentally removed the file before destroying your cluster.
- On AWS, the default worker MachineSets have been bumped to 120 GiB
volumes to increase our baseline performance from on [gp2's sliding
IOPS scale][aws-ebs-gp2-iops]. The new default worker volumes match
our master bump from 0.5.0.
- On OpenStack, the HAProxy configuration on the service VM is
dynamically updated as masters and workers are added and removed.
This supports console access, among other things.
- Several doc and internal cleanups.

### Fixed

- We no longer write distracting `ERROR: logging before flag.Parse...`
messages from our underlying Kubernetes libraries.
- On loading `install-config.yaml`, we now error on CIDRs whose IP is
not at the beginning of the masked subnet. For example, we now
error for `192.168.126.10/24`, since the beginning of that subnet is
`192.168.126.0`.
- On loading `install-config.yaml`, we now fill in defaults for
`replicas` when it is unset or explicitly `null`.
- We have fixed some issues with round-tripping assets between the
installer and the asset directory which lead to the reloaded assets
being falsely identified as dirty and rebuilt.
- On OpenStack, a new security rule exposes port 443 to allow
OpenShift web-console access.
- On OpenStack, credentials secret generation now respects the install
configuration's `cloud` value, and the secret name has been updated
from `openstack-creds` to `openstack-credentials`.
- On OpenStack, the `local-dns` service will now restart on failure
(e.g. when the initial image pull fails) and it no longer sets the
name of the container (so we can always re-run it without running
into duplicate name issues).

### Removed

- On loading `install-config.yaml`, the installer no longer restricts
`networking.type` to a known value. If the network operator sees an
unrecognized type, it assumes the user is configurating networking
and doesn't react.
- We no longer seed `~core/.bash_history` on the bootstrap node, as
part of becoming less opinionated about which users are present on
the underlying operating system.
- On AWS, the `iamRoleName` machine-pool property is gone, and the
`podCIDR` networking property (deprecated in 0.4.0) is gone. The
install-config version has been bumped from `v1beta1` to `v1beta2`.
All users, regardless of platform, will need to update any saved
`install-config.yaml` to use the new version. IAM roles are being
replaced by [the credentials operator][credential-operator], and
while we still create IAM roles for our master, worker, and
bootstrap machines, we're removing the user-facing property now to
avoid making this breaking change later.
- On AWS, the bootstrap machine security group allowing kubelet access
(added in 0.10.1) has been removed. Static pod logs should soon be
available from journald (although they aren't yet).

leaking AWS resources despite `delete cluster` claiming success.
