Release notes for Cluster API Provider AWS (CAPA) v1.0.0

This version is compatible with Cluster API versions 1.0.x.

Documentation

Changelog since v0.7.0

Urgent Upgrade Notes

(No, really, you MUST read this before you upgrade)

• v1.0.0 is based on Cluster API v1beta1 and must be used in conjunction with Cluster API v1.0.x. (#2831, @randomvariable)
• All Cluster API Provider AWS API types have been graduated to v1beta1, this includes:
  • AWSCluster*, AWSMachine*, AWSManaged* and all experimental APIs, covering both EC2 and EKS.
  • clusterawsadm configuration has also graduated to v1beta1. Clusterawsadm is backwards compatible with v1alpha1 configuration files and they are semantically the same. Running clusterawsadm bootstrap iam print-config --config <old-file> will do an automated conversion to v1beta1.
• Cluster API Provider AWS will support upgrades directly from v1alpha3 to v1beta1 as well as v1alpha4 to v1beta1.
