+## v1.0.0-rc1
+
+### Added
+
+- The Slurm Helm Chart can now be configured with `PrologSlurmctld` and
+  `EpilogSlurmctld`.
+- Add arm64 support and multiarch manifest.
+- Added NodePort to `v1alpha1.ServiceSpec`.
+- Added pod hostname resolution of NodeSet pods.
+- Adds hostname label to pods for Slurm node mapping.
+- Synchronize Kubernetes node [un]cordon state to NodeSet pods and their Slurm
+  nodes. When Kubernetes nodes are cordoned, NodeSet pods running on those nodes
+  are also cordoned and their Slurm nodes drained. Those NodeSet pods remain
+  cordoned until the Kubernetes node becomes uncordoned.
+- Implements graceful nodeset pod disruption handling
+- Added metrics-server-bind-address command-line option for the slurm-operator
+  controller.
+- Added liveness probe to slurmrestd container, which will restart its pod if it
+  becomes unresponsive long enough.
+- Custom Slurm node drain message for kubectl cordon.
+- Adds dynamic node tainting.
+- Can now support hybrid clusters, where one or more Slurm components exist
+  externally to Kubernetes but be joined to the same Slurm cluster.
+
+### Fixed
+
+- Fixes parsing of `ServiceSpec` via `ServiceSpecWrapper`.
+- Correctly use global imagePullPolicy as the default value for all containers.
+- Determine cluster domain instead of assuming the default (`cluster.local`).
+- Update kubeVersion parsing to handle provider suffixes (e.g., GKE
+  `x.y.z-gke.a`).
+- Fixed odd number of arguments logger error when updating pod conditions.
+- Avoid needless NotFound errors when patching pod conditions.
+- Fixed regression where nodeset `partition.enabled` was not being respected.
+- Initial NodeSet no longer accidentally owns the worker service.
+- Fixed issue where changes to slurmd and/or logfile subobjects where not
+  causing a rolling update.
+- Fixed notation used to refer to LoginSets in installation docs.
+- Fixed documentation for uninstalling slurm-operator-crds.
+- When checking if a Slurm node is fully drained, the logic now follows closely
+  to how Slurm represents the drained state. There were certain edge cases that
+  could alleged the node was not drained when it actually was.
+- Check if Slurm node is [un]drain before requesting the opposite. This avoids a
+  race condition where an admin or script has applied [un]drain to the Slurm
+  node but the operator is not aware of it.
+- When Slurm nodes are put into drain state, the provided reason should not be
+  thrashed by subsequent drain requests.
+- Fixed installation instruction for cert-manager chart.
+- Fixes bug wereby slurm-controller hostname was set incorrectly.
+- Fixes per-nodeset partition creation.
+- Fixed chart installation failure where NOTES.txt failed to fetch value from
+  nested object where the parent was null.
+- Fixed imagePullPolicy in slurm-operator Helm chart.
+- Fixes edge case where Slurm node state is not reset when a worker pod migrates
+  kube nodes.
+- Reduce checksum collision during file change detection by using SHA256 instead
+  of MD5.
+- When `CgroupPlugin=disabled`, do not configure `PrologFlags=Contain` and other
+  parameters that depend on it.
+- Added liveness probe to slurmd container to restart the pod if slurmd crashes
+  after starting.
+- Prevent Slurm node undrain when node is down or notresponding.
+- Fixed reason prefixing behavior in MakeNodeUndrain.
+- Default webhook timeout is now consistent across all endpoints, respecing the
+  user input, otherwise using the Kubernetes default.
+- Fixed case where multiple env variables in LoginSet would cause the operator
+  to keep updating the LoginSet Deployment causing the underlying ReplicaSet to
+  endlessly thrash.
+- Fixed case where NodeSets being added or removed from the Slurm cluster was
+  not triggering a reconfigure.
+
+### Changed
+
+- Organized documentation into sub-directories.
+- Updates the paths used to refer to the user's home directory in installation
+  instructions.
+- Slurm node [un]drain activity now includes more context.
+- Made the NodeSet updateStrategy configurable in the Slurm helm chart. The
+  default minUnavailable was changed to 25%.
+- Shortened naming schema for health and metrics addresses.
+- Exposed addresses for health and metrics of the slurm-operator controller pod
+  via the Helm chart.
+- slurmctld - The reconfigure container is now a sidecar instead of main
+  container.
+- Reduced interval of the reconfigure check. After the kubelet updates mounted
+  files in the pod, a reconfigure will be issued more quickly.
+- All supplemental containers are now `corev1.Container`, allowing full
+  configuration.
+- Chart metadata is no longer applied to the pod template.
+- Updated NodeSet pod preStop to better indicate why the Slurm node was set to
+  DOWN before deletion.
+- Service metadata is now configurable separately from the pod template
+  metadata.
+- Webhooks avoid kube-system namespace.
+- Replaced slurm-exporter with a serviceMonitor that scrapes slurmctld directly.
+- Move to Slurm v44 API (from v43).
+
+### Removed
+
+- Removed defaulting webhooks.
+- Removed v1alpha1 CRDs to cleanly delineate v1 from v0 releases. Going forward,
+  old versions of CRDs in v1 releases will linger in a deprecated state and be
+  removed in future releases as needed.
