😎 Cozystack v0.34: K8s Version Selection and PVC Snapshots in Tenants, Windows and RouterOS on VMs, VPA for VPA

Our maintainers and contributors never stand still, and we’re already ready to present the next stable release of Cozystack v0.34. In this release, we continued working on expanding the functionality of the Vertical Pod Autoscaler, improving tenant clusters, enhancing the backup system, and moving toward platform decomposition. Below, we’ll cover the most important changes, and you can find the full list of fixes in the links at the end of the announcement.

Major Features and Improvements
- Enable users to select Kubernetes versions in tenant clusters. Supported versions range from 1.28 to 1.33, updated to the latest patches.
- Enable PVC snapshot capability in tenant Kubernetes clusters.
- Implement autoscaling for the Vertical Pod Autoscaler itself, ensuring that VPA has sufficient resources and reducing the number of configuration parameters that platform administrators have to manage.
- Enable running Windows and MikroTik RouterOS in Cozystack VMs. Add the bus option and always specify bootOrder for all disks.
- Explain how to back up and restore PostgreSQL using Velero backups.
- Support multi-zone configuration for S3 storage.
- Put YAML editor first when deploying and upgrading applications, as a more powerful option. Fix handling multiline strings.
- Numerous API improvements and progress toward the new UI: OpenAPI schema for apps, OpenAPI Schema refactoring, using singular resource names in Cozystack API.

Security
- Ensure that JWT signing keys in the SeaweedFS security configuration remain consistent across Helm upgrades. Resolve an upstream issue.
