Release notes for kOps 1.27 series

⚠ kOps 1.27 has not been released yet! ⚠

This is a document to gather the release notes prior to the release.

Significant changes

The default retention duration for the etcd backups is now set to 90 days. This behaviour can be overridden by setting spec.etcdClusters[*].manager.backupRetentionDays in the cluster spec.

As of Kubernetes version 1.27, all nodes will default to running with instance-metadata-service tokens required, with a max hop limit of 1. Newly created clusters will be configured as necessary to have these settings.

Nodes will now assign floating IPs when they are in a subnet that is of type Public. Previously they would do so when the respective topology was set to public.

Support for Kubernetes version 1.22 is deprecated and will be removed in kOps 1.28.
Support for Kubernetes version 1.23 is deprecated and will be removed in kOps 1.29.
Support for Ubuntu 18.04 is deprecated and will be removed in kOps 1.28.
Support for AWS Classic Load Balancer for API is deprecated and should not be used for newly created clusters.
All legacy addons are deprecated in favor of managed addons, including the metrics server addon and the autoscaler addon.

kOps needs maintainers for Canal, Flannel, Kube-Router, and Spotinst to keep versions up to date and move the integration from experimental to stable. If no volunteers step up by the time kOps 1.27 is released, support will be phased out.
