    `LSTMStateTuple`. The new behavior leads to proper dropout behavior for
    LSTMs and stacked LSTMs. This bug fix follows recommendations from published
    literature, but is a behavioral change. State dropout behavior may be
    customized via the new `dropout_state_filter_visitor` argument.

These notes detail the changes which purposefully break backwards compatibility with the previous version of Istio. The notes also mention changes which preserve backwards compatibility while introducing new behavior. Changes are only included if the new behavior would be unexpected to a user. These should be written in paragraph format with a title and content.

- The current behavior for Services that `IPFamilyPolicy` set as `PreferDualstack`. The current behavior when the cluster is upgraded to dual-stack is:
  - Services that have been set to IPFamilyPolicy = PreferDualstack will be upgraded when the service object is updated. e.g., when a user change a label.
  
  This behavior will change to:
