rails--rails/activesupport/CHANGELOG.md

• Fix ActiveSupport::TimeZone#utc_to_local with fractional seconds.

  When utc_to_local_returns_utc_offset_times is false and the time instance had fractional seconds the new UTC time instance was out by a factor of 1,000,000 as the Time.utc constructor takes a usec value and not a fractional second value.

  Andrew White

• Fix issue in Hash#deep_merge where it did not properly duplicate a nested Hash

  Marcel Eeken

• Add expires_at argument to ActiveSupport::Cache write and fetch to set a cache entry TTL as an absolute time.

  Rails.cache.write(key, value, expires_at: Time.now.at_end_of_hour)
  

  Jean Boussier

• Deprecate ActiveSupport::TimeWithZone.name so that from Rails 7.1 it will use the default implementation.

  Andrew White

• Tests parallelization is now disabled when running individual files to prevent the setup overhead.

  It can still be enforced if the environment variable PARALLEL_WORKERS is present and set to a value greater than 1.

  Ricardo Díaz

• Fix proxying keyword arguments in ActiveSupport::CurrentAttributes.

  Marcin Kołodziej

• Add Enumerable#maximum and Enumerable#minimum to easily calculate the maximum or minimum from extracted elements of an enumerable.

  payments = [Payment.new(5), Payment.new(15), Payment.new(10)]
  
  payments.minimum(:price) # => 5
  payments.maximum(:price) # => 15
  

  This also allows passing enumerables to fresh_when and stale? in Action Controller. See PR #41404 for an example.

• ActiveSupport::Cache::MemCacheStore now accepts an explicit nil for its addresses argument.

  config.cache_store = :mem_cache_store, nil
  
  # is now equivalent to
  
  config.cache_store = :mem_cache_store
  
  # and is also equivalent to
  
  config.cache_store = :mem_cache_store, ENV["MEMCACHE_SERVERS"] || "localhost:11211"
  
  # which is the fallback behavior of Dalli
  

  This helps those migrating from :dalli_store, where an explicit nil was permitted.

  Michael Overmeyer

• Add Enumerable#in_order_of to put an Enumerable in a certain order by a key.

  DHH

• ActiveSupport::Inflector.camelize behaves expected when provided a symbol :upper or :lower argument. Matches String#camelize behavior.

  Alex Ghiculescu

• Raises an ArgumentError when the first argument of ActiveSupport::Notification.subscribe is invalid.

  Vipul A M

• HashWithIndifferentAccess#deep_transform_keys now returns a HashWithIndifferentAccess instead of a Hash.

  Nathaniel Woodthorpe

• consume dalli’s cache_nils configuration as ActiveSupport::Cache's skip_nil when using MemCacheStore.

  Ritikesh G

• add RedisCacheStore#stats method similar to MemCacheStore#stats. Calls redis#info internally.
