+title: Nephio R6 Release Notes
+weight: 1
+---
+
+## Overview
+
+Nephio R6 is a maintenance release focused on stability, security, and platform improvements. This release includes:
+
+- **Platform enhancements**: Porch v1.5.6 with critical fixes, security patches, and performance improvements
+- **Security updates**: Golang upgraded to v1.25.6+ across all projects with dependency updates
+- **O2 IMS integration**: New REST Provision API for O-RAN O2 IMS functionality
+- **Documentation improvements**: Enhanced aesthetics, bug fixes, and migration of Porch documentation to its own dedicated site
+
+This release continues to demonstrate Nephio's core principles of intent-driven automation, configuration-as-data, and distributed actuation for managing cloud-native network functions at scale.
+
+## Prerequisites
+
+Refer to the  [Installation Guide]({{% relref "/docs/guides/install-guides/install-on-byoc.md#prerequisites" %}})    for the
+prerequisites on supported environments.
+
+## Support matrix
+
+The [Nephio sandbox demo]({{% relref "/docs/guides/install-guides/_index.md" %}}) environment requires hardware with the 
+following specifications:
+
+### OS support
+
+- **Ubuntu 22.04**
+- **Fedora 38**
+
+### System Requirements
+
+| Resource | Minimum | Recommended |
+|----------|---------|-------------|
+| vCPU     | 6       | 16          |
+| Memory   | 6 GB    | 32 GB       |
+| Disk     | 50 GB   | 200 GB      |
+
+{{% alert title="Note" color="primary" %}}
+
+The *Recommended* sizes above are required to execute the [Free5GC]({{% relref "/docs/guides/user-guides/usecase-user-guides/exercise-1-free5gc" %}}) 
+and [OAI RAN]({{% relref "/docs/guides/user-guides/usecase-user-guides/exercise-2-oai" %}}) use cases.
+
+{{% /alert %}}
+
+### Kubernetes version support
+
+| Min   | Max     |
+|-------|---------|
+| v1.26 | v1.32.0 |
+
+
+These installations have been verified on virtual machines (VMs) running on Google Cloud.
+
+## Features
+
+### Functionalities
+
+* Platform
+  * [Porch](https://github.com/nephio-project/porch/releases/tag/v1.5.6) fixes, security patches, and enhancements. 
+  See [Porch fixes and enhancements](#porch-fixes-and-enhancements) for more details.
+  * [Nephio](https://github.com/nephio-project/nephio/releases/tag/v6.0.0) fixes, security patches, and enhancements.
+  * O2 IMS REST Provision API added.
+
+* Documentation
+  * Improvements in aesthetics and bug fixes.
+  * Migration of the [Porch documentation](https://docs.porch.nephio.org/) to it's own project.
+
+* Security
+  * Golang version upgrades on all go based projects to >= v1.25.6
+  * Dependency upgrades 
+
+## Limitations
+
+* Intercluster networking is not dynamic. Therefore, as more clusters are deployed, some manual tweaking will be needed 
+for intercluster communications.
+* Provisioning of the VLAN interfaces on the nodes is currently performed manually.
+* Observability between workload clusters to the management cluster is limited. 
+You may need to connect directly to the workload cluster via kubectl to resolve any deployment issues.
+* The web UI features are limited to the viewing and editing of packages, resources in those packages, and their deployment. 
+Additional features will be added in subsequent releases.
+* When the capacities of the UPF, SMF, and AMF NFs are changed, the free5GC operator on the workload cluster will 
+instantiate a new POD with correspondingly modified resources (CPU, memory, and so on). During this process, the pod will restart. This is a limitation of free5GC.
+* Only Gitea works with automated cluster provisioning to create new repositories and join them to Nephio. 
+To use a different Git provider, you must manually provision the cluster repositories, register them to the Nephio management server, and set up Config Sync on the workload cluster.
+* The web UI does not require authentication in the current demo configuration. Testing of the web UI with authentication configured has not yet been done.
+* The web UI only shows the resources in the default namespace.
+* While many types of Git authentication are supported, testing has only been done with token-based Git authentication in Gitea.
+
+## Known issues and workarounds
+
+*  Packages may take time to be approved by the auto-approval controller. If they appear to have frozen, it may help to 
+restart the Porch and the Nephio controllers using the following commands:
+
+  ```bash
+  kubectl -n porch-system rollout restart deploy porch-server
+  kubectl -n nephio-system rollout restart deploy nephio-controller
+  ```
+* Occasional calls to `porchctl rpkg copy` may fail with the following message:
+
+  `Error: Internal error occurred: error applying patch: conflict: fragment line
+  does not match src line`.
+
+  If such a message appears, then retry in a little while, as this error may resolve itself. Restarting Porch may also help.
