• Add resource name to the ArgumentError that's raised when invalid :only or :except options are given to #resource or #resources

  This makes it easier to locate the source of the problem, especially for routes drawn by gems.

  Before:

  :only and :except must include only [:index, :create, :new, :show, :update, :destroy, :edit], but also included [:foo, :bar]

  After:

  Route `resources :products` - :only and :except must include only [:index, :create, :new, :show, :update, :destroy, :edit], but also included [:foo, :bar]

• Add check_collisions option to ::ActionDispatch::Session::CacheStore.

  Newly generated session ids use 128 bits of randomness, which is more than enough to ensure collisions can't happen, but if you need to harden sessions even more, you can enable this option to check in the session store that the id is indeed free you can enable that option. This however incurs an extra write on session creation.

• In ExceptionWrapper, match backtrace lines with built templates more often, allowing improved highlighting of errors within do-end blocks in templates. Fix for Ruby 3.4 to match new method labels in backtrace.

• Allow setting content type with a symbol of the Mime type.

  # Before
  response.content_type = "text/html"
  
  # After
  response.content_type = :html
