-*   Introduce `ActiveSupport::ActionableError`.
 
-    Actionable errors let's you dispatch actions from Rails' error pages. This
-    can help you save time if you have a clear action for the resolution of
-    common development errors.
 
-    The de-facto example are pending migrations. Every time pending migrations
-    are found, a middleware raises an error. With actionable errors, you can
-    run the migrations right from the error page. Other examples include Rails
-    plugins that need to run a rake task to setup themselves. They can now
-    raise actionable errors to run the setup straight from the error pages.
-
-    Here is how to define an actionable error:
-
-    ```ruby
-    class PendingMigrationError < MigrationError #:nodoc:
-      include ActiveSupport::ActionableError
-
-      action "Run pending migrations" do
-        ActiveRecord::Tasks::DatabaseTasks.migrate
-      end
-    end
-    ```
-
-    To make an error actionable, include the `ActiveSupport::ActionableError`
-    module and invoke the `action` class macro to define the action. An action
-    needs a name and a procedure to execute. The name is shown as the name of a
-    button on the error pages. Once clicked, it will invoke the given
-    procedure.
-
-    *Vipul A M*, *Yao Jie*, *Genadi Samokovarov*
-
-*   Preserve `html_safe?` status on `ActiveSupport::SafeBuffer#*`.
-
-    Before:
-
-        ("<br />".html_safe * 2).html_safe? #=> nil
-
-    After:
-
-        ("<br />".html_safe * 2).html_safe? #=> true
-
-    *Ryo Nakamura*
-
-*   Calling test methods with `with_info_handler` method to allow minitest-hooks
-    plugin to work.
-
-    *Mauri Mustonen*
-
-*   The Zeitwerk compatibility interface for `ActiveSupport::Dependencies` no
-    longer implements `autoloaded_constants` or `autoloaded?` (undocumented,
-    anyway). Experience shows introspection does not have many use cases, and
-    troubleshooting is done by logging. With this design trade-off we are able
-    to use even less memory in all environments.
-
-    *Xavier Noria*
-
-*   Depends on Zeitwerk 2, which stores less metadata if reloading is disabled
-    and hence uses less memory when `config.cache_classes` is `true`, a standard
-    setup in production.
-
-    *Xavier Noria*
-
-*   In `:zeitwerk` mode, eager load directories in engines and applications only
-    if present in their respective `config.eager_load_paths`.
-
-    A common use case for this is adding `lib` to `config.autoload_paths`, but
-    not to `config.eager_load_paths`. In that configuration, for example, files
-    in the `lib` directory should not be eager loaded.
-
-    *Xavier Noria*
-
-*   Fix bug in Range comparisons when comparing to an excluded-end Range
-
-    Before:
-
-        (1..10).cover?(1...11) # => false
-
-    After:
-
-        (1..10).cover?(1...11) # => true
-
-    With the same change for `Range#include?` and `Range#===`.
-
-    *Owen Stephens*
-
-*   Use weak references in descendants tracker to allow anonymous subclasses to
-    be garbage collected.
-
-    *Edgars Beigarts*
-
-*   Update `ActiveSupport::Notifications::Instrumenter#instrument` to make
-    passing a block optional. This will let users use
-    `ActiveSupport::Notifications` messaging features outside of
-    instrumentation.
-
-    *Ali Ibrahim*
-
-*   Fix `Time#advance` to work with dates before 1001-03-07
-
-    Before:
-
-        Time.utc(1001, 3, 6).advance(years: -1) # => 1000-03-05 00:00:00 UTC
-
-    After
-
-        Time.utc(1001, 3, 6).advance(years: -1) # => 1000-03-06 00:00:00 UTC
-
-    Note that this doesn't affect `DateTime#advance` as that doesn't use a proleptic calendar.
-
-    *Andrew White*
-
-*   In Zeitwerk mode, engines are now managed by the `main` autoloader. Engines may reference application constants, if the application is reloaded and we do not reload engines, they won't use the reloaded application code.
-
-    *Xavier Noria*
-
-*   Add support for supplying `locale` to `transliterate` and `parameterize`.
-
-        I18n.backend.store_translations(:de, i18n: { transliterate: { rule: { "ü" => "ue" } } })
-
-        ActiveSupport::Inflector.transliterate("ü", locale: :de) # => "ue"
-        "Fünf autos".parameterize(locale: :de) # => "fuenf-autos"
-        ActiveSupport::Inflector.parameterize("Fünf autos", locale: :de) # => "fuenf-autos"
-
-    *Kaan Ozkan*, *Sharang Dashputre*
-
-*   Allow `Array#excluding` and `Enumerable#excluding` to deal with a passed array gracefully.
-
-        [ 1, 2, 3, 4, 5 ].excluding([4, 5]) # => [ 1, 2, 3 ]
-
-    *DHH*
-
-*   Renamed `Array#without` and `Enumerable#without` to `Array#excluding` and `Enumerable#excluding`, to create parity with
-    `Array#including` and `Enumerable#including`. Retained the old names as aliases.
-
-    *DHH*
-
-*   Added `Array#including` and `Enumerable#including` to conveniently enlarge a collection with more members using a method rather than an operator:
-
-        [ 1, 2, 3 ].including(4, 5) # => [ 1, 2, 3, 4, 5 ]
-        post.authors.including(Current.person) # => All the authors plus the current person!
-
-    *DHH*
-
-
-## Rails 6.0.0.beta3 (March 11, 2019) ##
-
-*   No changes.
-
-
-## Rails 6.0.0.beta2 (February 25, 2019) ##
-
-*   New autoloading based on [Zeitwerk](https://github.com/fxn/zeitwerk).
-
-    *Xavier Noria*
-
-*   Revise `ActiveSupport::Notifications.unsubscribe` to correctly handle Regex or other multiple-pattern subscribers.
-
-    *Zach Kemp*
-
-*   Add `before_reset` callback to `CurrentAttributes` and define `after_reset` as an alias of `resets` for symmetry.
-
-    *Rosa Gutierrez*
-
-*   Remove the `` Kernel#` `` override that suppresses ENOENT and accidentally returns nil on Unix systems.
-
-    *Akinori Musha*
-
-*   Add `ActiveSupport::HashWithIndifferentAccess#assoc`.
-
-    `assoc` can now be called with either a string or a symbol.
-
-    *Stefan Schüßler*
-
-*   Add `Hash#deep_transform_values`, and `Hash#deep_transform_values!`.
-
-    *Guillermo Iguaran*
-
-
-## Rails 6.0.0.beta1 (January 18, 2019) ##
-
-*   Remove deprecated `Module#reachable?` method.
-
-    *Rafael Mendonça França*
-
-*   Remove deprecated `#acronym_regex` method from `Inflections`.
-
-    *Rafael Mendonça França*
-
-*   Fix `String#safe_constantize` throwing a `LoadError` for incorrectly cased constant references.
-
-    *Keenan Brock*
-
-*   Preserve key order passed to `ActiveSupport::CacheStore#fetch_multi`.
-
-    `fetch_multi(*names)` now returns its results in the same order as the `*names` requested, rather than returning cache hits followed by cache misses.
-
-    *Gannon McGibbon*
-
-*   If the same block is `included` multiple times for a Concern, an exception is no longer raised.
-
-    *Mark J. Titorenko*, *Vlad Bokov*
-
-*   Fix bug where `#to_options` for `ActiveSupport::HashWithIndifferentAccess`
-    would not act as alias for `#symbolize_keys`.
-
-    *Nick Weiland*
-
-*   Improve the logic that detects non-autoloaded constants.
-
-    *Jan Habermann*, *Xavier Noria*
-
-*   Deprecate `ActiveSupport::Multibyte::Unicode#pack_graphemes(array)` and `ActiveSuppport::Multibyte::Unicode#unpack_graphemes(string)`
-    in favor of `array.flatten.pack("U*")` and `string.scan(/\X/).map(&:codepoints)`, respectively.
-
-    *Francesco Rodríguez*
-
-*   Deprecate `ActiveSupport::Multibyte::Chars.consumes?` in favor of `String#is_utf8?`.
-
-    *Francesco Rodríguez*
-
-*   Fix duration being rounded to a full second.
-    ```
-      time = DateTime.parse("2018-1-1")
-      time += 0.51.seconds
-    ```
-    Will now correctly add 0.51 second and not 1 full second.
-
-    *Edouard Chin*
-
-*   Deprecate `ActiveSupport::Multibyte::Unicode#normalize` and `ActiveSuppport::Multibyte::Chars#normalize`
-    in favor of `String#unicode_normalize`
-
-    *Francesco Rodríguez*
-
-*   Deprecate `ActiveSupport::Multibyte::Unicode#downcase/upcase/swapcase` in favor of
-    `String#downcase/upcase/swapcase`.
-
-    *Francesco Rodríguez*
-
-*   Add `ActiveSupport::ParameterFilter`.
-
-    *Yoshiyuki Kinjo*
-
-*   Rename `Module#parent`, `Module#parents`, and `Module#parent_name` to
-    `module_parent`, `module_parents`, and `module_parent_name`.
-
-    *Gannon McGibbon*
-
-*   Deprecate the use of `LoggerSilence` in favor of `ActiveSupport::LoggerSilence`
-
-    *Edouard Chin*
-
-*   Deprecate using negative limits in `String#first` and `String#last`.
-
-    *Gannon McGibbon*, *Eric Turner*
-
-*   Fix bug where `#without` for `ActiveSupport::HashWithIndifferentAccess` would fail
-    with symbol arguments
-
-    *Abraham Chan*
-
-*   Treat `#delete_prefix`, `#delete_suffix` and `#unicode_normalize` results as non-`html_safe`.
-    Ensure safety of arguments for `#insert`, `#[]=` and `#replace` calls on `html_safe` Strings.
-
-    *Janosch Müller*
-
-*   Changed `ActiveSupport::TaggedLogging.new` to return a new logger instance instead
-    of mutating the one received as parameter.
-
-    *Thierry Joyal*
-
-*   Define `unfreeze_time` as an alias of `travel_back` in `ActiveSupport::Testing::TimeHelpers`.
-
-    The alias is provided for symmetry with `freeze_time`.
-
-    *Ryan Davidson*
-
-*   Add support for tracing constant autoloads. Just throw
-
-        ActiveSupport::Dependencies.logger = Rails.logger
-        ActiveSupport::Dependencies.verbose = true
-
-    in an initializer.
-
-    *Xavier Noria*
-
-*   Maintain `html_safe?` on html_safe strings when sliced.
-
-        string = "<div>test</div>".html_safe
-        string[-1..1].html_safe? # => true
-
-    *Elom Gomez*, *Yumin Wong*
-
-*   Add `Array#extract!`.
-
-    The method removes and returns the elements for which the block returns a true value.
-    If no block is given, an Enumerator is returned instead.
-
-        numbers = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
-        odd_numbers = numbers.extract! { |number| number.odd? } # => [1, 3, 5, 7, 9]
-        numbers # => [0, 2, 4, 6, 8]
-
-    *bogdanvlviv*
-
-*   Support not to cache `nil` for `ActiveSupport::Cache#fetch`.
-
-        cache.fetch('bar', skip_nil: true) { nil }
-        cache.exist?('bar') # => false
-
-    *Martin Hong*
-
-*   Add "event object" support to the notification system.
-    Before this change, end users were forced to create hand made artisanal
-    event objects on their own, like this:
-
-        ActiveSupport::Notifications.subscribe('wait') do |*args|
-          @event = ActiveSupport::Notifications::Event.new(*args)
-        end
-
-        ActiveSupport::Notifications.instrument('wait') do
-          sleep 1
-        end
-
-        @event.duration # => 1000.138
-
-    After this change, if the block passed to `subscribe` only takes one
-    parameter, the framework will yield an event object to the block.  Now
-    end users are no longer required to make their own:
-
-        ActiveSupport::Notifications.subscribe('wait') do |event|
-          @event = event
-        end
-
-        ActiveSupport::Notifications.instrument('wait') do
-          sleep 1
-        end
-
-        p @event.allocations # => 7
-        p @event.cpu_time    # => 0.256
-        p @event.idle_time   # => 1003.2399
-
-    Now you can enjoy event objects without making them yourself.  Neat!
-
-    *Aaron "t.lo" Patterson*
-
-*   Add cpu_time, idle_time, and allocations to Event.
-
-    *Eileen M. Uchitelle*, *Aaron Patterson*
-
-*   RedisCacheStore: support key expiry in increment/decrement.
-
-    Pass `:expires_in` to `#increment` and `#decrement` to set a Redis EXPIRE on the key.
-
-    If the key is already set to expire, RedisCacheStore won't extend its expiry.
-
-        Rails.cache.increment("some_key", 1, expires_in: 2.minutes)
-
-    *Jason Lee*
-
-*   Allow `Range#===` and `Range#cover?` on Range.
-
-    `Range#cover?` can now accept a range argument like `Range#include?` and
-    `Range#===`. `Range#===` works correctly on Ruby 2.6. `Range#include?` is moved
-    into a new file, with these two methods.
-
-    *Requiring active_support/core_ext/range/include_range is now deprecated.*
-    *Use `require "active_support/core_ext/range/compare_range"` instead.*
-
-    *utilum*
-
-*   Add `index_with` to Enumerable.
-
-    Allows creating a hash from an enumerable with the value from a passed block
-    or a default argument.
-
-        %i( title body ).index_with { |attr| post.public_send(attr) }
-        # => { title: "hey", body: "what's up?" }
-
-        %i( title body ).index_with(nil)
-        # => { title: nil, body: nil }
-
-    Closely linked with `index_by`, which creates a hash where the keys are extracted from a block.
-
-    *Kasper Timm Hansen*
-
-*   Fix bug where `ActiveSupport::TimeZone.all` would fail when tzinfo data for
-    any timezone defined in `ActiveSupport::TimeZone::MAPPING` is missing.
-
-    *Dominik Sander*
-
-*   Redis cache store: `delete_matched` no longer blocks the Redis server.
-    (Switches from evaled Lua to a batched SCAN + DEL loop.)
-
-    *Gleb Mazovetskiy*
-
-*   Fix bug where `ActiveSupport::Cache` will massively inflate the storage
-    size when compression is enabled (which is true by default). This patch
-    does not attempt to repair existing data: please manually flush the cache
-    to clear out the problematic entries.
-
-    *Godfrey Chan*
-
-*   Fix bug where `URI.unescape` would fail with mixed Unicode/escaped character input:
-
-        URI.unescape("\xe3\x83\x90")  # => "バ"
-        URI.unescape("%E3%83%90")  # => "バ"
-        URI.unescape("\xe3\x83\x90%E3%83%90")  # => Encoding::CompatibilityError
-
-    *Ashe Connor*, *Aaron Patterson*
-
-*   Add `before?` and `after?` methods to `Date`, `DateTime`,
-    `Time`, and `TimeWithZone`.
-
-    *Nick Holden*
-
-*   `ActiveSupport::Inflector#ordinal` and `ActiveSupport::Inflector#ordinalize` now support
-    translations through I18n.
-
-        # locale/fr.rb
-
-        {
-          fr: {
-            number: {
-              nth: {
-                ordinals: lambda do |_key, number:, **_options|
-                  if number.to_i.abs == 1
-                    'er'
-                  else
-                    'e'
-                  end
-                end,
-
-                ordinalized: lambda do |_key, number:, **_options|
-                  "#{number}#{ActiveSupport::Inflector.ordinal(number)}"
-                end
-              }
-            }
-          }
-        }
-
-
-    *Christian Blais*
-
-*   Add `:private` option to ActiveSupport's `Module#delegate`
-    in order to delegate methods as private:
-
-        class User < ActiveRecord::Base
-          has_one :profile
-          delegate :date_of_birth, to: :profile, private: true
-
-          def age
-            Date.today.year - date_of_birth.year
-          end
-        end
-
-        # User.new.age  # => 29
-        # User.new.date_of_birth
-        # => NoMethodError: private method `date_of_birth' called for #<User:0x00000008221340>
-
-    *Tomas Valent*
-
-*   `String#truncate_bytes` to truncate a string to a maximum bytesize without
-    breaking multibyte characters or grapheme clusters like 👩‍👩‍👦‍👦.
-
-    *Jeremy Daer*
-
-*   `String#strip_heredoc` preserves frozenness.
-
-        "foo".freeze.strip_heredoc.frozen?  # => true
-
-    Fixes that frozen string literals would inadvertently become unfrozen:
-
-        # frozen_string_literal: true
-
-        foo = <<-MSG.strip_heredoc
-          la la la
-        MSG
-
-        foo.frozen?  # => false !??
-
-    *Jeremy Daer*
-
-*   Rails 6 requires Ruby 2.5.0 or newer.
-
-    *Jeremy Daer*, *Kasper Timm Hansen*
-
-*   Adds parallel testing to Rails.
-
-    Parallelize your test suite with forked processes or threads.
-
-    *Eileen M. Uchitelle*, *Aaron Patterson*
