This is a maintenance release including two changes:
[up-switch] and up.element.hide() now hides elements using an [hidden] attribute instead of setting an inline style. Users can override the CSS for [hidden] to hide an element in a different way, e.g. by giving it a zero height.
    
      If you're upgrading from an older Unpoly version you should load unpoly-migrate.js
      to polyfill deprecated APIs.
    
    
      Changes handled by unpoly-migrate.js are not considered breaking changes.
    
  
See our upgrading guide for details.
