## Release notes for kOps 1.28 series
|
|
|
|
# Significant changes
|
|
|
|
## AWS
|
|
|
|
* Node Termination Handler is now enabled by default.
|
|
|
|
## GCP
|
|
|
|
* [metadata-proxy](https://github.com/kubernetes/kubernetes/tree/master/cluster/addons/metadata-proxy) is no longer deployed on GCP clusters for Kubernetes 1.29+.
|
|
|
|
# Breaking changes
|
|
|
|
## AWS
|
|
|
|
* The `kops get assets --copy` command no longer sets object-level public-read ACLs in the destination fileRepository.
|
|
|
|
## OpenStack
|
|
|
|
* If storing the state in an S3 bucket, it is now required to either [deactivate gossip support](https://github.com/kubernetes/kops/issues/15684#issuecomment-1645384421) (`--dns=none`) or - for example - provide the credentials via cloud-init. Due to changes in [PR#15646](https://github.com/kubernetes/kops/pull/15646/files#diff-c1c852aea92883d3117fae99c1610c5cdcbc217f5aa3b340f23b5dd02e971d99L136-L145) the `S3_*` variables will not get passed on to the boot script of the [nodes anymore](https://github.com/kubernetes/kops/pull/15691). As a result the `kops-configuration.service` will throw an `EnvAccessKeyNotFound: failed to find credentials in the environment.` error and they will not join the cluster. Deactivating the gossip support will make the nodes contact the API servers for the bootstrap information.

|
## Other breaking changes
|
|
|
|
* Support for Kubernetes version 1.22 has been removed.
|
|
|
|
* Support for Ubuntu 18.04 is has been removed.
|
|
|
|
* Support for Canal and Flannel have been removed for Kubernetes 1.28 and later.
|
|
|
|
* RHEL-based distros will no longer have `wget`, `curl`, `python2`, and `git` packages installed. Install them with [hooks](/cluster_spec/#hooks) if needed.
|
|
|
|
* The [default IPv4 service cluster range](https://github.com/kubernetes/kops/pull/15866) is now `100.64.0.0/13`. As this was previously calculated from `nonMasqueradeCIDR` if `serviceClusterIPRange` was not explicitly set, it may be necessary to set it to this value ([the first 1/8](https://github.com/kubernetes/kops/pull/15866/files#diff-5e44add4b8da1d5b1c7119b6cc5a5f42a45c555332f51262162b29790e78f479L397-L404) of the `nonMasqueradeCIDR`).
