Breaking Changes

●Issue #1

Connections to a Service IP using a port not listed in the Service's `spec.ports` are now refused. This aligns Linkerd behavior with current Kubernetes behavior. Users must ensure all connections target ports defined in the Service specification.

Migration Steps

  1. 1
    Review Service definitions to ensure all targeted ports are explicitly listed in `spec.ports` to avoid connection refusals.

Release Summary

This release introduces stricter enforcement against connecting to undefined Service ports, aligning Linkerd behavior with Kubernetes standards, and includes several dependency updates and minor fixes.
