> [!WARNING]
|
||||
> A patch release [0.33.2](github.com/cozystack/cozystack/releases/tag/v0.33.2) fixing a regression in 0.33.0 has been released.
|
||||
> It is recommended to skip this version and upgrade to [0.33.2](github.com/cozystack/cozystack/releases/tag/v0.33.2) instead.

|
||||
## Feature Highlights
|
||||
|
||||
### Unified CPU and Memory Allocation Management
|
||||
|
||||
Since version 0.31.0, Cozystack introduced a single-point-of-truth configuration variable `cpu-allocation-ratio`,
|
||||
making CPU resource requests and limits uniform in Virtual Machines managed by KubeVirt.
|
||||
The new release 0.33.0 introduces `memory-allocation-ratio` and expands both variables to all managed applications and tenant resource quotas.
|
||||
|
||||
Resource presets also respect the allocation ratios and behave in the same way as explicit resource definitions.
|
||||
The new resource definition format is concise and simple for platform users.
|
||||
|
||||
```yaml
|
||||
# resource definition in the configuration
|
||||
resources:
|
||||
cpu: <defined cpu value>
|
||||
memory: <defined memory value>
|
||||
```
|
||||
|
||||
It results in Kubernetes resource requests and limits, based on defined values and the universal allocation ratios:
|
||||
|
||||
```yaml
|
||||
# actual requests and limits, provided to the application
|
||||
resources:
|
||||
limits:
|
||||
cpu: <defined cpu value>
|
||||
memory: <defined memory value>
|
||||
requests:
|
||||
cpu: <defined cpu value / cpu-allocation-ratio>
|
||||
memory: <defined memory value / memory-allocation-ratio>
|
||||
```
|
||||
|
||||
When updating from earlier Cozystack versions, resource configuration in managed applications will be automatically migrated to the new format.
|
||||
|
||||
### Backing up and Restoring Data in Tenant Kubernetes
|
||||
|
||||
One of the main features of the release is backup capability for PVCs in tenant Kubernetes clusters.
|
||||
It enables platform and tenant administrators to back up and restore data used by services in the tenant clusters.
|
||||
|
||||
This new functionality in Cozystack is powered by [Velero](https://velero.io/) and needs an external S3-compatible storage.
|
||||
|
||||
## Support for NFS Storage
|
||||
|
||||
Cozystack now supports using NFS shared storage with a new optional system module.
|
||||
See the documentation: https://cozystack.io/docs/operations/storage/nfs/.
|
||||
|
||||
