• 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.

  Firefox fires click events even if the click was triggered by non-primary mouse keys such as right- or scroll-wheel-clicks.
  For example, right-clicking a link such as the one described below (with an underlying ajax request registered on click) should not cause that request to occur.

  <%= link_to 'Remote', remote_path, class: 'remote', remote: true, data: { type: :json } %>

  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

  ActiveSupport::Dependencies.logger = Rails.logger

  string = "<div>test</div>".html_safe

• 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.

  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

        nth: {
          ordinals: lambda do |_key, number:, **_options|

              '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

    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>

• String#strip_heredoc preserves frozenness.

  "foo".freeze.strip_heredoc.frozen?  # => true
  

  Fixes that frozen string literals would inadvertently become unfrozen:

  foo = <<-MSG.strip_heredoc
    la la la
  MSG
  
  foo.frozen?  # => false !??

  PR #34528 addresses the inconsistent behaviour when attribute is defined for an ignored column. The following test

    def deserialize(value)
      "Developer: #{value}"
    end
  end
  
  class AttributedDeveloper < ActiveRecord::Base
    self.table_name = "developers"
  
    attribute :name, DeveloperName.new
  
    self.ignored_columns += ["name"]
  end
  
  developer = AttributedDeveloper.create
  developer.update_column :name, "name"
  
  loaded_developer = AttributedDeveloper.where(id: developer.id).select("*").first

• Use request object for context if there's no controller

  There is no controller instance when using a redirect route or a
  mounted rack application so pass the request object as the context
  when resolving dynamic CSP sources in this scenario.

  Fixes #34200.

  Andrew White

• Apply mapping to symbols returned from dynamic CSP sources

  Previously if a dynamic source returned a symbol such as :self it
  would be converted to a string implicity, e.g:

  policy.default_src -> { :self }
  

  would generate the header:

  Content-Security-Policy: default-src self
  

  and now it generates:

  Content-Security-Policy: default-src 'self'
