### Documentation

- Fix ALPHA stability level reference link ([#98641](https://github.com/kubernetes/kubernetes/pull/98641), [@Jeffwan](https://github.com/Jeffwan)) [SIG Auth, Cloud Provider, Instrumentation and Storage]

### Failing Test

The Cluster API effort is currently undergoing a complete rehaul of the existing codebase, moving off Terraform and into using govmomi directly.

### SIG-windows

SIG Windows focused on stability and reliability of our existing feature set. We primarily fixed bugs as we march towards a near future stable release.

## Action Required

- Fixes a 1.30+ regression in connection stability for exec / attach / portforward requests initiated using a websocket client ([#130253](https://github.com/kubernetes/kubernetes/pull/130253), [@fuweid](https://github.com/fuweid)) [SIG API Machinery, CLI and Testing]
