## Automation

### RCTL Support for ARM

Benefit

Run RCTL natively on ARM-based environments

An ARM-based RCTL binary, compatible with both **Linux** and **macOS**, is now supported in addition to x86 architecture. This enhancement helps with:

- Improved performance on Apple Silicon (M1/M2/M3 Macs)
- Native support on ARM-based cloud environments (e.g., AWS Graviton, Ampere)
- Consistency across heterogeneous developer and CI/CD environments

## Environment Manager

### Support for Agent Pools

Benefit

Easier and more flexible management of agents for Day-2 operations.

With this enhancement, it is now possible to group agents into **pools**. This provides two main advantages:

- Add/remove agents without needing to update associations (e.g., environment templates). This is extremely useful for scenarios like Day-2 operations, retiring agents, or scaling up/down.
- Load balancing across agents within the pool for improved reliability and efficiency.

> **Note:** Agent Pool support is currently available only with **Environment Manager resources** (e.g., environment template, resource template, environment). Repository support will be added in a future release.

For more details, please refer to the [Agent Pool Documentation](https://docs.rafay.co/gitops/gitops_agentpool/).

Note

If you are using GitOps System Sync, you will need to update to the latest agent version included in this release (v3.6.2) in order to use the Agent Pool feature.

### Environments (Save & Continue Later option)

Benefit

Improves usability by allowing users to save progress without losing work.

In cases where users do not have all required inputs to provision an environment, they can now **save their work and return later**. A new **“Save & Continue Later”** option has been introduced in the UI, making it easier to configure inputs incrementally and deploy when ready.

### Listing Environments

Benefit

Enhances navigation and discoverability for end users.

On the **Environments listing page**, users can now filter not only by **Status**, but also by:

- Labels
- Environment Template
- Version

This makes it easier to quickly locate the specific environment of interest.

### Feature Enhancements
