Rails 8.0.3 (September 22, 2025)¶ ↑

• ActiveSupport::FileUpdateChecker does not depend on Time.now to prevent unnecessary reloads with time travel test helpers

  Jan Grodowski

• Fix ActiveSupport::BroadcastLogger from executing a block argument for each logger (tagged, info, etc.).

  Jared Armstrong

• Make ActiveSupport::Logger freeze-friendly.

  Joshua Young

• Fix ActiveSupport::HashWithIndifferentAccess#transform_keys! removing defaults.

  Hartley McGuire

• Fix ActiveSupport::HashWithIndifferentAccess#tranform_keys! to handle collisions.

  If the transformation would result in a key equal to another not yet transformed one, it would result in keys being lost.

  Before:

  >> {a: 1, b: 2}.with_indifferent_access.transform_keys!(&:succ)
  => {"c" => 1}
  

  After:

  >> {a: 1, b: 2}.with_indifferent_access.transform_keys!(&:succ)
  => {"c" => 1, "d" => 2}
  

  Jason T Johnson, Jean Boussier

• Fix ActiveSupport::Cache::MemCacheStore#read_multi to handle network errors.

  This method specifically wasn't handling network errors like other codepaths.

  Alessandro Dal Grande

• Fix configuring RedisCacheStore with raw: true.

  fatkodima

• Fix Enumerable#sole for infinite collections.

Rails 8.0.2.1 (August 13, 2025)¶ ↑

• No changes.

Rails 8.0.2 (March 12, 2025)¶ ↑

• Fix setting to_time_preserves_timezone from new_framework_defaults_8_0.rb.

  fatkodima

• Fix Active Support Cache fetch_multi when local store is active.

  fetch_multi now properly yield to the provided block for missing entries that have been recorded as such in the local store.

  Jean Boussier

• Fix execution wrapping to report all exceptions, including Exception.

  If a more serious error like SystemStackError or NoMemoryError happens, the error reporter should be able to report these kinds of exceptions.

  Gannon McGibbon

• Fix RedisCacheStore and MemCacheStore to also handle connection pool related errors.

  These errors are rescued and reported to Rails.error.

  Jean Boussier

• Fix ActiveSupport::Cache#read_multi to respect version expiry when using local cache.

  zzak

• Fix ActiveSupport::MessageVerifier and ActiveSupport::MessageEncryptor configuration of on_rotation callback.

  verifier.rotate(old_secret).on_rotation { ... }
  

  Now both work as documented.

  Jean Boussier

• Fix ActiveSupport::MessageVerifier to always be able to verify both URL-safe and URL-unsafe payloads.

  This is to allow transitioning seemlessly from either configuration without immediately invalidating all previously generated signed messages.

  Jean Boussier, Florent Beaurain, Ali Sepehri

• Fix cache.fetch to honor the provided expiry when :race_condition_ttl is used.

  cache.fetch("key", expires_in: 1.hour, race_condition_ttl: 5.second) do
    "something"
  end
  

  In the above example, the final cache entry would have a 10 seconds TTL instead of the requested 1 hour.

  Dhia

• Better handle procs with splat arguments in set_callback.

  Radamés Roriz

• Fix String#mb_chars to not mutate the receiver.

  Previously it would call force_encoding on the receiver, now it dups the receiver first.

  Jean Boussier

• Improve ErrorSubscriber to also mark error causes as reported.

  This avoid some cases of errors being reported twice, notably in views because of how errors are wrapped in ActionView::Template::Error.

  Jean Boussier

• Fix Module#module_parent_name to return the correct name after the module has been named.

  When called on an anonymous module, the return value wouldn't change after the module was given a name later by being assigned to a constant.

  mod = Module.new
  mod.module_parent_name # => "Object"
  MyModule::Something = mod
  mod.module_parent_name # => "MyModule"
  

  Jean Boussier

Rails 8.0.1 (December 13, 2024)¶ ↑

• Fix a bug in ERB::Util.tokenize that causes incorrect tokenization when ERB tags are preceeded by multibyte characters.

  Martin Emde

• Restore the ability to decorate methods generated by class_attribute.

  It always has been complicated to use Module#prepend or an alias method chain to decorate methods defined by class_attribute, but became even harder in 8.0.

  This capability is now supported for both reader and writer methods.

  Jean Boussier

Rails 8.0.0.1 (December 10, 2024)¶ ↑

• No changes.

Rails 8.0.0 (November 07, 2024)¶ ↑

• No changes.

Rails 8.0.0.rc2 (October 30, 2024)¶ ↑

• No changes.

Rails 8.0.0.rc1 (October 19, 2024)¶ ↑

• Remove deprecated support to passing an array of strings to ActiveSupport::Deprecation#warn.

  Rafael Mendonça França

• Remove deprecated support to setting attr_internal_naming_format with a @ prefix.

  Rafael Mendonça França

• Remove deprecated ActiveSupport::ProxyObject.

  Rafael Mendonça França

• Don't execute i18n watcher on boot. It shouldn't catch any file changes initially, and unnecessarily slows down boot of applications with lots of translations.

  Gannon McGibbon, David Stosik

• Fix ActiveSupport::HashWithIndifferentAccess#stringify_keys to stringify all keys not just symbols.

  Previously:

  { 1 => 2 }.with_indifferent_access.stringify_keys[1] # => 2
  

  After this change:

  { 1 => 2 }.with_indifferent_access.stringify_keys["1"] # => 2
  

  This change can be seen as a bug fix, but since it behaved like this for a very long time, we're deciding to not backport the fix and to make the change in a major release.

  Jean Boussier

Rails 8.0.0.beta1 (September 26, 2024)¶ ↑

• Include options when instrumenting ActiveSupport::Cache::Store#delete and ActiveSupport::Cache::Store#delete_multi.

  Adam Renberg Tamm

• Print test names when running rails test -v for parallel tests.

  John Hawthorn, Abeid Ahmed

• Deprecate Benchmark.ms core extension.

  The benchmark gem will become bundled in Ruby 3.5

  Earlopain

• ActiveSupport::TimeWithZone#inspect now uses ISO 8601 style time like Time#inspect

  John Hawthorn

• ActiveSupport::ErrorReporter#report now assigns a backtrace to unraised exceptions.

  Previously reporting an un-raised exception would result in an error report without a backtrace. Now it automatically generates one.

  Jean Boussier

• Add escape_html_entities option to ActiveSupport::JSON.encode.

  This allows for overriding the global configuration found at ActiveSupport.escape_html_entities_in_json for specific calls to to_json.

  This should be usable from controllers in the following manner:

  class MyController < ApplicationController
    def index
      render json: { hello: "world" }, escape_html_entities: false
    end
  end
  

  Nigel Baillie

• Raise when using key which can't respond to to_sym in EncryptedConfiguration.

  As is the case when trying to use an Integer or Float as a key, which is unsupported.

  zzak

• Deprecate addition and since between two Time and ActiveSupport::TimeWithZone.

  Previously adding time instances together such as 10.days.ago + 10.days.ago or 10.days.ago.since(10.days.ago) produced a nonsensical future date. This behavior is deprecated and will be removed in Rails 8.1.

  Nick Schwaderer

• Support rfc2822 format for Time#to_fs & Date#to_fs.

  Akshay Birajdar

• Optimize load time for Railtie#initialize_i18n. Filter I18n.load_paths passed to the file watcher to only those under Rails.root. Previously the watcher would grab all available locales, including those in gems which do not require a watcher because they won't change.

  Nick Schwaderer

• Add a filter option to in_order_of to prioritize certain values in the sorting without filtering the results by these values.

  Igor Depolli

• Improve error message when using assert_difference or assert_changes with a proc by printing the proc's source code (MRI only).

  Richard Böhme, Jean Boussier

• Add a new configuration value :zone for ActiveSupport.to_time_preserves_timezone and rename the previous true value to :offset. The new default value is :zone.

  Jason Kim, John Hawthorn

• Align instrumentation payload[:key] in ActiveSupport::Cache to follow the same pattern, with namespaced and normalized keys.

  Frederik Erbs Spang Thomsen

• Fix travel_to to set usec 0 when with_usec is false and the given argument String or DateTime.
