    view-switcher-title: Remove policy
    
    Use auto only, people can easily reimplement the widget themselves if they
    need other policies.

+The "policy" property has been removed, the behavior is similar to the `auto`
+policy. If you had used `wide` or `narrow` policies, use an [class@Adw.Squeezer]
+with an [class@Adw.ViewSwitcher] and an [class@Adw.WindowTitle] inside, with the
+switcher having the desired policy.

 ### Adapt to [class@Adw.Avatar] API Changes
 
 The `HdyAvatar:loadable-icon` property has been removed along with its getter
