[2025/07/22] The Enhancement Proposal is merged. Working on the first code changes in the core autoscaler. * [03 Jul] The PR is still open, but there appears to be agreement with the community, so it should be approved as soon as the maintainers can prioritize it. [17 Jun] Targetting 4.21. PR open. it carries risk due to uncertainties of how fast things will progress upstream. * [12 Feb] not yet started   [27 Feb] discussions started. Work partially delayed due to the need for support for the new features and release of the MTO [2025/03/05] same as past week. [2025/03/11] A PR to update the enhancement proposal has been opened to add the architecture and OS in the contract between Cluster API and the Cloud Providers' controllers. However, no Cloud Providers Controller implements the reconciliation for all the other fields yet, and we depend on that implementation to execute the work to add the architecture support. From the initial discussions, the first provider that will implement it and that could migrate out of the MachineAPI umbrella is AWS in 4.21. After agreement about the enhancement proposal update, this work will continue by (a) implementing the required changes in the cluster-autoscaler, (b) implementing or supporting the autoscaler team with the status reconcilers in the cloud providers, starting from the AWS one so that we get support for this from day0 [2025/03/25] Still pending the reviews in the upstream PR. I'll attend the next cluster API meeting to catch with the reviewers.
