- `CONTROLLER` argument can now be supplied in different ways (Rails::WelcomeController, Rails::Welcome, rails/welcome)
- If `CONTROLLER` argument was supplied but it does not exist, will warn the user that this controller does not exist
- If `CONTROLLER` argument was supplied and no routes could be found matching this filter, will warn the user that no routes were found matching the supplied filter
- If no routes were defined in the config/routes.rb file, will warn the user with the original message
- The root method is defined and documented in Base module and
decorated in Resources module.
- The documentation in Base module actually talks about method
signature of decorated method from Resources module.
- Argument handling was moved to decorated method in
977455cc2e
to handle options such as :as with directly passed path parameter.
- To avoid the confusion, removed original root method from Base module
and only kept overridden version in Resources module.

- Earlier only Hash was allowed as params argument to url_helpers.
- Now ActionController::Parameters instances will also be allowed.
- If the params are not secured then it will raise an ArgumentError to
indicate that constructing URLs with non-secure params is not recommended.
- Fixes#22832.
- AC::Parameters#convert_parameters_to_hashes should return filtered or
unfiltered values based on whether it is called from `to_h` or `to_unsafe_h`
instead of always defaulting to `to_h`.
- Fixes#22841
During the `5.0.0.beta1` release, the CHANGELOGs got an entry like the
following:
```
* No changes.
```
It is kinda confusing as there are indeed changes after it. Not a
biggie, just a small pass over the CHANGELOGs.
[ci skip]
The ActionPack test suite had a handful of these warnings when run. This
was due to `assert_response` being tested outside the context of a
controller instance where those instance variables would already have
been initialized.
If you're not familiar with how the `Referer` header works, you likely
won't understand why you need to provide a fallback or under what
circumstances it would be used.
Hopefully this clarifies things a bit.
When calling `to_h` on an `ActionController::Parameters` instance it would
`deep_dup` its internal parameters.
This inadvertently called `dup` on a passed Active Record model which would
create new models. Fix by only dupping Ruby's Arrays and Hashes.
Applications that use `redirect_to :back` can be forced to 500 by
clients that do not send the HTTP `Referer` (sic) header.
`redirect_back` requires the user to consider this possibility up front
and avoids this trivially-caused application error.
`redirect_to :back` is a somewhat common pattern in Rails apps, but it
is not completely safe. There are a number of circumstances where HTTP
referrer information is not available on the request. This happens often
with bot traffic and occasionally to user traffic depending on browser
security settings.
When there is no referrer available on the request, `redirect_to :back`
will raise `ActionController::RedirectBackError`, usually resulting in
an application error.
`redirect_back` takes a required `fallback_location` keyword argument
that specifies the redirect when the referrer information is not
available. This prevents 500 errors caused by
`ActionController::RedirectBackError`.
