Rails 7.2.3 (October 28, 2025)

• Fix Enumerable#sole to return the full tuple instead of just the first element of the tuple.

  Olivier Bellone

• Fix parallel tests hanging when worker processes die abruptly.

  Previously, if a worker process was killed (e.g., OOM killed, kill -9) during parallel test execution, the test suite would hang forever waiting for the dead worker.

  Joshua Young

• ::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

• 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 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

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

  Martin Emde

Rails 7.2.2.2 (August 13, 2025)

• No changes.

Rails 7.2.2.1 (December 10, 2024)

• No changes.

Rails 7.2.2 (October 30, 2024)

  Adam Renberg Tamm

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

  John Hawthorn, Abeid Ahmed

Rails 7.2.1.2 (October 23, 2024)

• No changes.

Rails 7.2.1.1 (October 15, 2024)

• No changes.

Rails 7.2.1 (August 22, 2024)

• No changes.

Rails 7.2.0 (August 09, 2024)

• Fix delegate_missing_to allow_nil: true when called with implict self

  class Person
    delegate_missing_to :address, allow_nil: true
  
    def address
      nil
    end
  
    def berliner?
      city == "Berlin"
    end
  end
  
  Person.new.city # => nil
  Person.new.berliner? # undefined local variable or method `city' for an instance of Person (NameError)

  Jean Boussier

• Add logger as a dependency since it is a bundled gem candidate for Ruby 3.5

  Earlopain

• Define Digest::UUID.nil_uuid, which returns the so-called nil UUID.

  Xavier Noria

• Support duration type in ::ActiveSupport::XmlMini.

  heka1024

• Remove deprecated ActiveSupport::Notifications::Event#children and ActiveSupport::Notifications::Event#parent_of?.

  Rafael Mendonça França

• Remove deprecated support to call the following methods without passing a deprecator:

  • deprecate
  • deprecate_constant
  • ActiveSupport::Deprecation::DeprecatedObjectProxy.new
  • ActiveSupport::Deprecation::DeprecatedInstanceVariableProxy.new
  • ActiveSupport::Deprecation::DeprecatedConstantProxy.new
  • assert_deprecated
  • assert_not_deprecated
  • collect_deprecations

  Rafael Mendonça França

• Remove deprecated ::ActiveSupport::Deprecation delegation to instance.

  Rafael Mendonça França

• Remove deprecated SafeBuffer#clone_empty.

  Rafael Mendonça França

• Remove deprecated #to_default_s from Array, Date, DateTime and Time.

  Rafael Mendonça França

• Remove deprecated support to passing Dalli::Client instances to MemCacheStore.

  Rafael Mendonça França

• Remove deprecated config.active_support.use_rfc4122_namespaced_uuids.

  Rafael Mendonça França

• Remove deprecated config.active_support.remove_deprecated_time_with_zone_name.

  Rafael Mendonça França

• Remove deprecated config.active_support.disable_to_s_conversion.

  Rafael Mendonça França

• Remove deprecated support to bolding log text with positional boolean in ActiveSupport::LogSubscriber#color.

  Rafael Mendonça França

• Remove deprecated constants ActiveSupport::LogSubscriber::CLEAR and ActiveSupport::LogSubscriber::BOLD.

  Rafael Mendonça França

• Remove deprecated support for config.active_support.cache_format_version = 6.1.

  Rafael Mendonça França

• Remove deprecated :pool_size and :pool_timeout options for the cache storage.

  Rafael Mendonça França

• Warn on tests without assertions.

  ::ActiveSupport::TestCase now warns when tests do not run any assertions. This is helpful in detecting broken tests that do not perform intended assertions.

  fatkodima

• Support hexBinary type in ::ActiveSupport::XmlMini.

  heka1024

• Deprecate ::ActiveSupport::ProxyObject in favor of Ruby's built-in BasicObject.

  Earlopain

• stub_const now accepts a exists: false parameter to allow stubbing missing constants.

  Jean Boussier

• Make ::ActiveSupport::BacktraceCleaner copy filters and silencers on dup and clone.

  Previously the copy would still share the internal silencers and filters array, causing state to leak.

  Jean Boussier

• Updating Astana with Western Kazakhstan TZInfo identifier.

  Damian Nelson

• Add filename support for ActiveSupport::Logger.logger_outputs_to?.

  logger = Logger.new('/var/log/rails.log')
  ActiveSupport::Logger.logger_outputs_to?(logger, '/var/log/rails.log')

  Christian Schmidt

• Include IPAddr#prefix when serializing an IPAddr using the ::ActiveSupport::MessagePack serializer.

  This change is backward and forward compatible — old payloads can still be read, and new payloads will be readable by older versions of Rails.

  Taiki Komaba

• Add default: support for ActiveSupport::CurrentAttributes.attribute.

  class Current < ActiveSupport::CurrentAttributes
    attribute :counter, default: 0
  end

  Sean Doyle

• Yield instance to Object#with block.

  client.with(timeout: 5_000) do |c|
    c.get("/commits")
  end

  Sean Doyle

• Use logical core count instead of physical core count to determine the default number of workers when parallelizing tests.

  Jonathan Hefner

• Fix Time.now/DateTime.now/Date.today to return results in a system timezone after #travel_to.

  There is a bug in the current implementation of #travel_to: it remembers a timezone of its argument, and all stubbed methods start returning results in that remembered timezone. However, the expected behavior is to return results in a system timezone.

  Aleksei Chernenkov

• Add ErrorReported#unexpected to report precondition violations.

  For example:

  def edit
    if published?
      Rails.error.unexpected("[BUG] Attempting to edit a published article, that shouldn't be possible")
      return false
    end
    # ...
  end

  The above will raise an error in development and test, but only report the error in production.

  Jean Boussier

• Make the order of read_multi and write_multi notifications for Cache::Store#fetch_multi operations match the order they are executed in.

  Adam Renberg Tamm

• Make return values of Cache::Store#write consistent.

  The return value was not specified before. Now it returns true on a successful write, nil if there was an error talking to the cache backend, and false if the write failed for another reason (e.g. the key already exists and unless_exist: true was passed).

  Sander Verdonschot

• Fix logged cache keys not always matching actual key used by cache action.

  Hartley McGuire

• Improve error messages of assert_changes and assert_no_changes.

  assert_changes error messages now display objects with .inspect to make it easier to differentiate nil from empty strings, strings from symbols, etc. assert_no_changes error messages now surface the actual value.

  pcreux

• Fix #to_fs(:human_size) to correctly work with negative numbers.

  Earlopain

• Fix BroadcastLogger#dup so that it duplicates the logger's broadcasts.

  Andrew Novoselac

• Fix issue where bootstrap.rb overwrites the level of a BroadcastLogger's broadcasts.

  Andrew Novoselac

• Fix compatibility with the semantic_logger gem.

  The semantic_logger gem doesn't behave exactly like stdlib logger in that SemanticLogger#level returns a Symbol while stdlib Logger#level returns an Integer.

  This caused the various LogSubscriber classes in Rails to break when assigned a SemanticLogger instance.

  Jean Boussier, ojab

• Fix MemoryStore to prevent race conditions when incrementing or decrementing.

  Pierre Jambet

• Implement HashWithIndifferentAccess#to_proc.

  Previously, calling #to_proc on HashWithIndifferentAccess object used inherited #to_proc method from the Hash class, which was not able to access values using indifferent keys.
