*   Add alias `ActionDispatch::Http::UploadedFile#to_io` to
    `ActionDispatch::Http::UploadedFile#tempfile`.

    *Tim Linquist*

*   Returns null type format when format is not know and controller is using `any`
    format block.

    Fixes #14462.

    *Rafael Mendonça França*

*   Improve routing error page with fuzzy matching search.

    *Winston*

*   Append link to bad code to backtrace when exception is SyntaxError.

    *Boris Kuznetsov*

*   Swapped the parameters of assert_equal in `assert_select` so that the
    proper values were printed correctly

    Fixes #14422.

    *Vishal Lal*

*   The method `shallow?` returns false if the parent resource is a singleton so
    we need to check if we're not inside a nested scope before copying the :path
    and :as options to their shallow equivalents.

    Fixes #14388.

    *Andrew White*

*   Make logging of CSRF failures optional (but on by default) with the
    `log_warning_on_csrf_failure` configuration setting in
    `ActionController::RequestForgeryProtection`.

    *John Barton*

*   Fix URL generation in controller tests with request-dependent
    `default_url_options` methods.

    *Tony Wooster*
