([#64102](https://github.com/kubernetes/kubernetes/pull/64102), [@atombender](https://github.com/atombender))
* Added support for NFS relations on kubernetes-worker charm. ([#63817](https://github.com/kubernetes/kubernetes/pull/63817), [@hyperbolic2346](https://github.com/hyperbolic2346))

## 0.30.0

* Add support for Pydantic's ORM mode:
    * Updated documentation about SQL with SQLAlchemy, using Pydantic models with ORM mode, SQLAlchemy models with relations, separation of files, simplification of code and other changes. New docs: [SQL (Relational) Databases](https://fastapi.tiangolo.com/tutorial/sql-databases/).

### Juju
* The kubernetes-master, kubernetes-worker and kubeapi-load-balancer charms have gained an nrpe-external-master relation, allowing the integration of their monitoring in an external Nagios server.

- Fix network_programming_latency metric reporting for Endpoints/EndpointSlice deletions, where we don't have correct timestamp ([#95363](https://github.com/kubernetes/kubernetes/pull/95363), [@wojtek-t](https://github.com/wojtek-t)) [SIG Network and Scalability]

  - Don't update capacity if VMSS provisioning state is updating
  - Support allocatable resources overrides via VMSS tags
  - Add missing stable labels in template nodes
  - Proactively set instance status to deleting on node deletions
  
  ### Cluster API
  - Migrate interaction with the API from using internal types to using Unstructured
  - Improve tests to work better with constrained resources
  - Add support for node auto-discovery

- Relaxed API validation to allow pod node selector to be mutable for gated pods (additions only, no deletions or mutations). ([#116161](https://github.com/kubernetes/kubernetes/pull/116161), [@danielvegamyhre](https://github.com/danielvegamyhre))

- Fixed `JobTrackingWithFinalizers` that:
  - was declaring a job finished before counting all the created pods in the status
  - was leaving pods with finalizers, blocking pod and job deletions
   `JobTrackingWithFinalizers` is still disabled by default. ([#109486](https://github.com/kubernetes/kubernetes/pull/109486), [@alculquicondor](https://github.com/alculquicondor))

### SIG Big Data

During the 1.13 release cycle, SIG Big Data has been focused on community engagements relating to 3rd-party project integrations with Kubernetes. There have been no impacts on the 1.13 release.

### SIG CLI

- Enabled concurrent log rotation in kubelet. You can now configure the maximum number of concurrent rotations with the `containerLogMaxWorkers` setting, and adjust the monitoring interval with `containerLogMonitorInterval`.
