-### Kubernetes [hostPath][k8s-hostpath] volumes
+## Host resource sharing
 
-In Kata, Kubernetes hostPath volumes can mount host directories and
-regular files into the guest VM via filesystem sharing, if it is enabled
-through the `shared_fs` [configuration][runtime-config] flag.
-
-By default:
-
- - Non-TEE environment: Filesystem sharing is used to mount host files.
- - TEE environment: Filesystem sharing is disabled. Instead, host files
-   are copied into the guest VM when the container starts, and file
-   changes are *not* synchronized between the host and the guest.
-
-In some cases, the behavior of hostPath volumes in Kata is further
-different compared to `runc` containers:
-
-**Mounting host block devices**: When a hostPath volume is of type
-[`BlockDevice`][k8s-blockdevice], Kata hotplugs the host block device
-into the guest and exposes it directly to the container.
-
-**Mounting guest devices**: When the source path of a hostPath volume is
-under `/dev` (or `/dev` itself), and the path corresponds to a
-non-regular file (i.e., a device, directory, or any other special file)
-or is not accessible by the Kata shim, the Kata agent bind mounts the
-source path directly from the *guest* filesystem into the container.

-[k8s-blockdevice]: https://kubernetes.io/docs/concepts/storage/volumes/#hostpath-volume-types

-### Mounting `procfs` and `sysfs`
-
-For security reasons, the following mounts are disallowed:
-
-| Type              | Source    | Destination                      | Rationale      |
-|-------------------|-----------|----------------------------------|----------------|

-| `bind`            | `*`       | `/proc/*` (see exceptions below) | CVE-2019-16884 |
-| `proc \|\| sysfs` | `*`       | not a directory (e.g. symlink)   | CVE-2019-19921 |
-
-For bind mounts under /proc, these destinations are allowed:
-
- * `/proc/cpuinfo`
- * `/proc/diskstats`
- * `/proc/meminfo`
- * `/proc/stat`
- * `/proc/swaps`
- * `/proc/uptime`
- * `/proc/loadavg`
- * `/proc/net/dev`
-
-## Privileged containers
+### Privileged containers
 
 Privileged support in Kata is essentially different from `runc` containers.
-The container runs with elevated capabilities within the guest.
+The container runs with elevated capabilities within the guest and is granted
+access to guest devices instead of the host devices.
 This is also true with using `securityContext privileged=true` with Kubernetes.
 
-Importantly, the default behavior to pass the host devices to a
-privileged container is not supported in Kata Containers and needs to be
-disabled, see [Privileged Kata Containers](how-to/privileged.md).
+The container may also be granted full access to a subset of host devices
+(https://github.com/kata-containers/runtime/issues/1568).
 
-## Guest pulled container images
-
-When using features like **nydus guest-pull**, set user/group IDs explicitly in the pod spec.
-If the ID values are omitted:
-
-- Your workload might be executed with unexpected user/group ID values, because image layers
-  may be unavailable to containerd, so image config (including user/group) is not applied.
-- If using policy or genpolicy, the generated policy may detect these unexpected values and
-  reject the creation of workload containers.
-
-Set `securityContext` explicitly. Use **pod-level** `spec.securityContext` (for Pods) or
-`spec.template.spec.securityContext` (for controllers like Deployments) and/or **container-level**
-`spec.containers[].securityContext`. Include at least:
-- `runAsUser` — primary user ID
-- `runAsGroup` — primary group ID
-- `fsGroup` — volume group ownership (often reflected as a supplemental group)
-- `supplementalGroups` — list of additional group IDs (if needed)
-
-Example:
-
- ```yaml
- # Explicit user/group/supplementary groups to support nydus guest-pull
- securityContext:
-   runAsUser: 0
-   runAsGroup: 0
-   fsGroup: 0
-   supplementalGroups: [1, 2, 3, 4, 6, 10, 11, 20, 26, 27]
- ```
+See [Privileged Kata Containers](how-to/privileged.md) for how to configure some of this behavior.

 # How to do a Kata Containers Release
-
 This document lists the tasks required to create a Kata Release.
 
 ## Requirements
 
 - GitHub permissions to run workflows.
 
-## Release Model
+## Versioning
 
-Kata Containers follows a rolling release model with monthly snapshots.
-New features, bug fixes, and improvements are continuously integrated into
-`main`. Each month, a snapshot is tagged as a new `MINOR` release.
+The Kata Containers project uses [semantic versioning](http://semver.org/) for all releases.
+Semantic versions are comprised of three fields in the form:
 
-### Versioning
+```
+MAJOR.MINOR.PATCH
+```
 
-Releases use the `MAJOR.MINOR.PATCH` scheme. Monthly snapshots increment
-`MINOR`; `PATCH` is typically `0`. Major releases are rare (years apart) and
-signal significant architectural changes that may require updates to container
-managers (Containerd, CRI-O) or other infrastructure. Breaking changes in
-`MINOR` releases are avoided where possible, but may occasionally occur as
-features are deprecated or removed.
+When `MINOR` increases, the new release adds **new features** but *without changing the existing behavior*.
 
-### No Stable Branches
+When `MAJOR` increases, the new release adds **new features, bug fixes, or
+both** and which **changes the behavior from the previous release** (incompatible with previous releases).
 
-The Kata Containers project does not maintain stable branches (see
-[#9064](https://github.com/kata-containers/kata-containers/issues/9064)).
-Bug fixes land on `main` and ship in the next monthly snapshot rather than
-being backported. Downstream projects that need extended support or compliance
-certifications should select a monthly snapshot as their stable base and manage
-their own validation and patch backporting from there.
+A major release will also likely require a change of the container manager version used,
+-for example Containerd or CRI-O. Please refer to the release notes for further details.
+
+**Important** : the Kata Containers project doesn't have stable branches (see
+[this issue](https://github.com/kata-containers/kata-containers/issues/9064) for details).
+Bug fixes are released as part of `MINOR` or `MAJOR` releases only. `PATCH` is always `0`.
 
 ## Release Process
 
 ### Bump the `VERSION` and `Chart.yaml` file
 
-When the `kata-containers/kata-containers` repository is ready for a new
-release, first create a PR to set the release in the [`VERSION`](./../VERSION)
-file and update the `version` and `appVersion` in the
-[`Chart.yaml`](./../tools/packaging/kata-deploy/helm-chart/kata-deploy/Chart.yaml)
-file and have it merged.

+have it merged.
 
 ### Lock the `main` branch
 
-In order to prevent any PRs getting merged during the release process, and
-slowing the release process down, by impacting the payload caches, we have
-recently trialed setting the `main` branch to read only whilst the release
-action runs.

-# Toolchains
-
-As a community we want to strike a balance between having up-to-date toolchains, to receive the
-latest security fixes and to be able to benefit from new features and packages, whilst not being
-too bleeding edge and disrupting downstream and other consumers. As a result we have the following
-guidelines (note, not hard rules) for our go and rust toolchains that we are attempting to try out:
-
-## Go toolchain
-
-Go is released [every six months](https://go.dev/wiki/Go-Release-Cycle) with support for the
-[last two major release versions](https://go.dev/doc/devel/release#policy). We always want to
-ensure that we are on a supported version so we receive security fixes. To try and make
-things easier for some of our users, we aim to be using the older of the two supported major
-versions, unless there is a compelling reason to adopt the newer version.
-
-In practice this means that we bump our major version of the go toolchain every six months to
-version (1.x-1) in response to a new version (1.x) coming out, which makes our current version
-(1.x-2) no longer supported. We will bump the minor version whenever required to satisfy
-dependency updates, or security fixes.
-
-Our go toolchain version is recorded in [`versions.yaml`](../versions.yaml) under
-`.languages.golang.version` and should match with the version in our `go.mod` files.
-
-## Rust toolchain
-
-Rust has a [six week](https://doc.rust-lang.org/book/appendix-05-editions.html#:~:text=The%20Rust%20language%20and%20compiler,these%20tiny%20changes%20add%20up.)
-release cycle and they only support the latest stable release, so if we wanted to remain on a
-supported release we would only ever build with the latest stable and bump every 6 weeks.
-However feedback from our community has indicated that this is a challenge as downstream consumers
-often want to get rust from their distro, or downstream fork and these struggle to keep up with
-the six week release schedule. As a result the community has agreed to try out a policy of
-"stable-2", where we aim to build with a rust version that is two versions behind the latest stable
-version.
-
-In practice this should mean that we bump our rust toolchain every six weeks, to version
-1.x-2 when 1.x is released as stable and we should be picking up the latest point release
-of that version, if there were any.
-
-The rust-toolchain that we are using is recorded in [`rust-toolchain.toml`](../rust-toolchain.toml).
