# v1.15.0 (2023-09-18)

## Major Features

This release brings support for Secure Boot on platforms using UEFI boot; the Linux 6.1 kernel; systemd-networkd and systemd-resolved for host networking; and XFS as the filesystem for local storage.

These features are enabled by default in the new variants. Existing variants will continue to use earlier kernels, `wicked` for host networking, and EXT4 as the filesystem for local storage.

## Known Incompatibilities

* Variants using the 6.1 kernel (`aws-ecs-2`/`aws-ecs-2-nvidia`, `aws-k8s-1.28`/`aws-k8s-1.28-nvidia`, `vmware-k8s-1.28`, and `metal-k8s-1.28`) do not support [LustreFS](https://aws.amazon.com/fsx/lustre/) ([#3459])

## Deprecation Notice

The functionality to apply a hotpatch for log4j CVE-2021-44228 has been removed. The corresponding setting, `settings.oci-hooks.log4j-hotpatch-enabled`, is still available for backwards compatibility. However, it has no effect beyond printing a deprecation warning to the system logs. ([#3401])

* Update admin and control containers ([#3368])
* Update third party packages and dependencies ([#3362], [#3369], [#3330], [#3339], [#3355], [#3441], [#3456])

# v1.1.3 (2021-07-12)

Note: in the Bottlerocket v1.0.8 release, for the aws-k8s-1.20 and aws-k8s-1.21 variants, we set the default Kubernetes CPU manager policy to "static".
We heard from several users that this breaks usage of the Fluent Bit log processor.
In Bottlerocket v1.1.3, we've changed the default back to "none", but have added a setting so you can use the "static" policy if desired.
To do so, set `settings.kubernetes.cpu-manager-policy` to "static".
To do this in user data, for example, pass the following:

```toml
[settings.kubernetes]
cpu-manager-policy = "static"
```

## OS Changes

# v1.1.0 (2021-05-07)

## Deprecation Notice

The Kubernetes 1.16 variant, `aws-k8s-1.16`, will lose support in July, 2021.
Kubernetes 1.16 is no longer receiving support upstream.
We recommend replacing `aws-k8s-1.16` nodes with a later variant, preferably `aws-k8s-1.19` if your cluster supports it.
See [this issue](https://github.com/bottlerocket-os/bottlerocket/issues/1552) for more details.

## Important Notes

### New variants with new defaults

This release introduces two new variants, `aws-k8s-1.20` and `vmware-k8s-1.20`.
We plan for all new variants, including these, to contain the following changes:
* The kernel is Linux 5.10 rather than 5.4.
* The kernel lockdown mode is set to "integrity" rather than "none".

The ECS preview variant, `aws-ecs-1`, has also been updated with these changes.

Existing `aws-k8s` variants will not receive these changes as they could affect existing workloads.

### ECS task networking

The `aws-ecs-1` variant now supports the `awsvpc` mode of [ECS task networking](https://docs.aws.amazon.com/AmazonECS/latest/developerguide/task-networking.html).
This allocates an elastic network interface and private IP address to each task.

# v1.0.2 (2020-10-13)

## Breaking changes (for build process only)

* pubsys: automate setup of role and key ([#1133], [#1146])
* Store repos under repo name so you can build multiple ([#1135])

**Note:** these changes do not impact users of Bottlerocket AMIs or repos, only those who build Bottlerocket themselves.
If you use an `Infra.toml` file to automate publishing, you'll need to update the format of the file.
The root role and signing key definitions now live inside a repo definition, rather than at the top level of the file.
Please see the updated [Infra.toml.example](tools/pubsys/Infra.toml.example) file for a commented explanation of the new role and key configuration.

# v0.2.1 (2020-01-20)

## OS changes

* Make `signpost` usage clearer to avoid updating into empty partition ([#444]).
* Fix handling of wave bounds in `updog` that could result in seeing an update but not accepting it ([#539]).
* Add support for query parameters in repo requests to allow for basic telemetry ([#542]).
* Enable support for SELinux in OS packages (not yet enforcing) ([#579]).
* Make grub reboot when config or kernel loading fails so it can try other partition sets ([#585]).
* Add support for image "variants" with separate API models ([#578], [#588], [#589], [#591], [#597], [#613], [#625], [#626], [#627], [#653]).
  The default variant is "aws-k8s" for Kubernetes usage, and an "aws-dev" variant can be built that has a local Docker daemon and debug tools.
* Remove unused cri-tools package ([#602]).
* Update Linux kernel to 4.19.75-28.73.amzn2 ([#622]).
* Make containerd.service stop containerd-shims to fix shutdown/reboot delay ([#652]).
* Ensure `updog` only removes known extensions from migration filenames ([#662]).
* Add OS version to "pretty name" so it's visible in console log ([#663]).

## Documentation changes

* Reorganize "getting started" documentation for clarity ([#581]).
* Fix formatting of kube-proxy options in install guide ([#584]).
* Specify compatible cargo-deny version in install guide ([#631]).
* Fix typos and improve clarity of install guide ([#639]).

## Build changes

* Add scripts to ease Kubernetes conformance testing through Sonobuoy ([#530]).
* Add release metadata file to be used in future automation ([#556], [#594]).
* Update dependencies of third-party packages in base OS ([#595]).
* Update dependencies of Rust packages ([#598]).
* Update SDK container to include Rust 1.40.0, GCC 9.2, and other small fixes ([#603], [#628]).
* Fix aarch64 build failure for libcap ([#621]).
* Add initial container definitions and scripts for CI process ([#619], [#624], [#633], [#646], [#647], [#651], [#654], [#658]).

# v0.2.0 (2019-12-09)

## Breaking changes

* Several settings now have added validation for their contents.  Upgrades from v0.1 that use invalid settings values will result in a broken system.
  * Host container names (e.g. `admin` in `settings.host-containers.admin`) are restricted to ASCII alphanumeric characters and hyphens ([#450]).
  * `settings.kubernetes.api-server`, `settings.updates.metadata-base-url` and `target-base-url`, `settings.host-containers.*.sources`, and `settings.ntp.time-servers` are now validated to be URIs ([#549]).
  * `settings.kubernetes.cluster_name`, `settings.kubernetes.node-labels`, and `settings.kubernetes.node-taints` are now verified to fit Kubernetes naming conventions ([#549]).
  * Most settings values disallow multi-line strings ([#453], [#483]).
* Additional characters are permitted in API keys; for example, dots and slashes in Kubernetes labels. Downgrades from v0.2 that use dots and slashes in API keys will result in a broken system ([#511]).

## OS changes

* Add `dogswatch`, a Kubernetes operator for managing OS upgrades ([#239]).
* More accurately represent data type of update seed ([#430]).
* Retry host container pulls with exponential backoff ([#433]).
* Better model startup dependencies in systemd units ([#442]).
* Enable panic on disk corruption detected with dm_verity ([#445]).
* Add persistent storage for host containers, mapped to `/.bottlerocket/host-containers/[CONTAINER_NAME]` ([#450], [#555]).
* Persist SSH host keys for admin container ([#450]).
* Use admin container v0.2 by default ([#450], [#536]).
* Use control container v0.2 by default ([#472], [#536]).
* Print most critical errors to the console to aid debugging ([#476], [#479], [#546]).
* Update Linux kernel to 4.19.75-27.58.amzn2 ([#478]).
* Updated partitions are marked `successful` after services start ([#481]).
* Kernel config is available at `/proc/config.gz` ([#482]).
* Prepare `tough` for separate release, including:
  * Allow library consumers to override the transport mechanism ([#488]).
  * Merge `tough_schema` back into `tough` ([#496]).
  * Add locking around tough datastore write operations ([#497]).
* Simplify representation of default metadata ([#491]).
* `apiclient` (available via the host containers) exits non-zero on HTTP response errors ([#498]).
* `apiclient` builds as a static binary ([#552]).
* `/proc/kheaders.tar.xz` is enabled in the kernel ([#557]).
* `settings-committer` no longer errors at boot when there are no changes to commit ([#559]).
* `migrator` and `updog` set migrations executable before running to work around a v0.1.6 bug ([#561], [#567]).

## Documentation changes

* Document how to use Bottlerocket's default for the `nf_conntrack_max` kernel parameter when using `kube-proxy` ([#391]).
* Fix example user data for enabling admin container ([#448]).
* Update build documentation for using Docker instead of `buildkitd` ([#506]).
* Update recommended CNI plugin version ([#507]).
* Document `settings.ntp.time-servers` ([#550]).
* Update INSTALL.md to use the instance role created by `eksctl` instead of creating a new one ([#569]).

## Build changes

* Add `updata` tool, which builds update repository metadata ([#265]).
* Create versioned symlinks to output images ([#434]).
* Add code and CloudFormation template for TUF repository canary ([#490]).
* Move the TUF client library, `tough`, to [its own repository](https://github.com/awslabs/tough) and [crates.io packages](https://crates.io/crates/tough) ([#499]).
* Remove build dependency on the BuildKit daemon ([#506]).
* Switch to SDK container as toolchain for builds, rather than requiring local build of toolchain ([#525]).
* Turn `buildsys` into a binary and remove the `cascade` feature ([#562]).

# v0.1.6 (2019-10-21)

## OS changes

* The system fetches the pause container from ECR before starting `kubelet` ([#382]).
* New settings: `settings.kubernetes.node-labels` and `settings.kubernetes.node-taints` ([#390], [#408]).
* The control container has an `enable-admin-container` helper ([#405], [#413]). Made default in v0.2.0 ([#472]).
* Rust dependencies updated ([#410]).
* `thar-be-settings` added trace-level messages in the client module ([#411]).
* `updog` no longer checks for migrations from new root images ([#416]).
* `pluto` was cleaned up to create an HTTP connection more consistently ([#419]).
* Settings that are usually generated may have defaults, and `settings.kubernetes.max-pods` defaults to `110` if the EC2 instance type cannot be determined ([#420]).
* The admin container MOTD is clearer about where the host's filesystem is mounted ([#424]).
* `block-party` (used in `growpart` and `signpost`) errors are better structured ([#425]).
* `thar-be-settings` logs render errors when running in `--all` mode ([#427]).
* [Recommended `sysctl` settings from the Kernel Self Protection Project](https://kernsec.org/wiki/index.php/Kernel_Self_Protection_Project/Recommended_Settings#sysctls) are now used ([#435]).
* `acpid` is enabled by default to handle power button signals sent by EC2 on stop/restart/terminate events ([#437]).
* `host-ctr` correctly fetches images from non-ECR registries ([#439]; this regression occurred after v0.1.5).

## Build changes

* amiize uses a short connection timeout when testing SSH connectivity ([#409]).
* `tuftool` only downloads an arbitrary `root.json` with `--allow-root-download` ([#421]).
* BuildKit updated to v0.6.2 ([#423], [#429]).
* First-party Rust code is built in the same `rpmbuild` invocation to improve build times ([#428]).
* `tuftool` correctly uses the `--timestamp-{version,expires}` arguments instead of the `--snapshot-{version,expires}` arguments in the timestamp role ([#438]).
* `tuftool` accepts relative dates ([#438]).

## Documentation changes

* The `sources/updater` crates are better documented ([#381]).
* INSTALL.md's subnet selection documentation is improved ([#422]).
