+# Release Notes for v0.15.0
+
+Release Date: July 23rd, 2025
+
+This release is based on [3.19.1](https://github.com/kata-containers/kata-containers/releases/tag/3.19.1) of Kata Containers
+and [v0.11.0](https://github.com/confidential-containers/enclave-cc/releases/tag/v0.11.0) of enclave-cc.
+
+Trustee and the guest components use KBS protocol v0.4.0.
+
+Please see the [quickstart guide](https://confidentialcontainers.org/docs/getting-started/) or [project documentation](https://confidentialcontainers.org/docs) for more information.
+
+
+## What's New
+
+* Attestation can account for confidential devices attached to a guest in addition to the CPU.
+  So far only one confidential device is supported (the Deep Computing Unit from Hygon),
+  but more are coming soon.
+* The full (plaintext) Init-Data is transmitted to Trustee where it is provided as input
+  to the KBS policy. This allows KBS policies to check configuration fields in the Init-Data.
+* The image-rs registry config file can be specified directly in the CDH config, allowing it
+  to be provisioned via Init-Data.
+* Trustee has Prometheus support, allowing admins to track attestation metrics. 
+* Trustee can store resources with HashiCorp Vault.
+* Trustee can be configured to allow cross-origin requests, such as from browser-based tools.
+* Trustee supports reference values of any type that can be represented as JSON including
+  complex types like maps and lists.
+* The KBS-Client can be used to set reference values of multiple types using the KBS admin
+  interface.
+* Trustee has more sophisticated [CC eventlog](https://uefi.org/specs/UEFI/2.11/38_Confidential_Computing.html#virtual-platform-cc-event-log) parsing, allowing boot information to be parsed into TCB claims.
+* When using Trustee with Docker compose, the required admin keypair is automatically generated. 
+* Trustee can attest SNP guests on Milan, Genoa, and Turin hosts with report version 3 or 4.
+
+## Hardware Support
+
+Attestation is supported and tested on three platforms: Intel TDX, AMD SEV-SNP, and IBM SE.
+Not all features have been tested on every platform, but those based on attestation
+are expected to work on the platforms above.
+
+Make sure your host platform is compatible with the hypervisor and guest kernel
+provisioned by CoCo.
+
+This release has been tested on the following stacks:
+
+### AMD SEV-SNP
+
+* Processor: AMD EPYC 7413
+* Kernel: 6.12.0-snp-host-adc218676 (upstream 6.11+) 
+* OS: Ubuntu 22.04.4 LTS
+* k8s: v1.30.1 (Kubeadm)
+* Kustomize: v4.5.4
+
+### Intel TDX
+
+* Kernel: [6.8.0-1022-intel](https://git.launchpad.net/~kobuk-team/ubuntu/+source/linux-intel/tree/?h=noble-main-next)
+* OS: Ubuntu 24.04 LTS
+* k8s: v1.30.2 (Kubeadm)
+* Kustomize: v5.0.4-0.20230601165947-6ce0bf390ce3
+
+### Secure Execution on IBM zSystems (s390x) running LinuxONE
+
+* Hardware: IBM Z16 LPAR
+* Kernel: 5.15.0-113-generic
+* OS: Ubuntu 22.04.1 LTS
+* k8s: v1.28.4 (Kubeadm)
+* Kustomize: v5.3.0
+
+## Limitations
+
+The following are limitations and known issues with this release.
+
+* Credentials for authenticated registries are exposed to the host.
+* Not all features are tested on all platforms.
+* Nydus snapshotter support is not mature.
+  * Nydus snapshotter sometimes fails to pull an image.
+  * Host pulling with Nydus snapshotter is not yet enabled.
+  * Nydus snapshotter is not supported with enclave-cc.
+* Pulling container images inside guest may have negative performance implications including greater resource usage and slower startup.
+* `crio` support is still evolving.
+* Platform support is rapidly changing
+* SELinux is not supported on the host and must be set to permissive if in use.
+* Complete integration with Kubernetes is still in progress.
+  * Existing APIs do not fully support the CoCo security and threat model. [More info](https://github.com/confidential-containers/confidential-containers/issues/53)
+  * Some commands accessing confidential data, such as `kubectl exec`, may either fail to work, or incorrectly expose information to the host
+* The CoCo community aspires to adopting open source security best practices, but not all practices are adopted yet.

+# Release Notes for v0.16.0
+
+Release Date: September 26th, 2025
+
+This release is based on [3.21.0](https://github.com/kata-containers/kata-containers/releases/tag/3.21.0) of Kata Containers
+and [v0.11.0](https://github.com/confidential-containers/enclave-cc/releases/tag/v0.11.0) of enclave-cc.
+
+Trustee and the guest components use KBS protocol v0.4.0.
+
+Please see the [quickstart guide](https://confidentialcontainers.org/docs/getting-started/) or [project documentation](https://confidentialcontainers.org/docs) for more information.
+
+## Deprecation Notices
+* Support for process-based confidential computing via enclave-cc will be removed in the v0.18.0 release.
+  The enclave-cc project will be archived.
+* This will be the last release of CoCo and Trustee that supports `simple` attestation tokens.
+  Today, EAR attestation tokens are the default, but Trustee can be configured to use `simple` tokens.
+  This option will be removed.
+
+## Breaking Changes
+
+* Previously the Init-Data was set for a pod via the `io.katacontainers.config.runtime.cc_init_data` annotation.
+  Now the `io.katacontainers.config.hypervisor.cc_init_data` annotation must be used.
+
+## What's New
+
+* The affirming resource policy now checks that every submod is affirming. With multi-device attestation,
+  KBS policies should be aware of all submods.
+* Experimental support for attesting some NVIDIA GPUs, such as the H100. Either ITA or the Trustee
+  Attestation Service can be used to verify the device evidence, with some limitations.
+* Experimental support for using pre-provisioned VMs in cloud-api-adaptor via "bring-your-own-machine (BYOM) provider
+* Runtime measurements can be extended from inside a workload container using a REST API.
+* Improved support for runtime measurements with AAEL on TDX
+* Trustee supports AMD-SNP guests with report version 5.
+* Additional/improved TCB claims generated by TDX verifier.
+* Extractor modules can now receive configuration if required.
+* SWID/RIM-IM extractor improved.
+* Confidential guest kernel updated to v6.16.7 with certain security-focused configs.
+* CSV verifier supports AAEL.
+* Eventlog parsing supports SM3 hashes.
+* A default GPU attestation policy is provided by Trustee, but it is very limited.
+* eHSM sealed secret backend no longer enabled by default.
+* evidence-getter tool now exposes primary and additional evidence.
+
+## Bug Fixes
+
+* Fixed issue where Init-Data checks could be maliciously bypassed when using dm-verity rootfs, such as with the base `kata-qemu-tdx` runtime. [GHSA-989w-4xr2-ww9m](https://github.com/kata-containers/kata-containers/security/advisories/GHSA-989w-4xr2-ww9m)
+* Fixed issue with attestation service policy endpoint permissions
+* Fixed issue with AR4SI vectors containing underscores
+* Various RUST advisories resolved by updating crates.
+
+## Hardware Support
+
+Attestation is supported and tested on three platforms: Intel TDX, AMD SEV-SNP, and IBM SE.
+Not all features have been tested on every platform, but those based on attestation
+are expected to work on the platforms above.
