*   Deprecate using `Range#include?` method to check the inclusion of a value
    in a date time range. It is recommended to use `Range#cover?` method
    instead of `Range#include?` to check the inclusion of a value
    in a date time range.

    *Vishal Telangre*

*   Support added for a `round_mode` parameter, in all number helpers. (See: `BigDecimal::mode`.)

    ```ruby
    number_to_currency(1234567890.50, precision: 0, round_mode: :half_down) # => "$1,234,567,890"
    number_to_percentage(302.24398923423, precision: 5, round_mode: :down) # => "302.24398%"
    number_to_rounded(389.32314, precision: 0, round_mode: :ceil) # => "390"
    number_to_human_size(483989, precision: 2, round_mode: :up) # => "480 KB"
    number_to_human(489939, precision: 2, round_mode: :floor) # => "480 Thousand"

    485000.to_s(:human, precision: 2, round_mode: :half_even) # => "480 Thousand"
    ```

    *Tom Lord*

*   `Array#to_sentence` no longer returns a frozen string.

    Before:

        ['one', 'two'].to_sentence.frozen?
        # => true

    After:

        ['one', 'two'].to_sentence.frozen?
        # => false

    *Nicolas Dular*

*   When an instance of `ActiveSupport::Duration` is converted to an `iso8601` duration string, if `weeks` are mixed with `date` parts, the `week` part will be converted to days.
    This keeps the parser and serializer on the same page.

    ```ruby
    duration = ActiveSupport::Duration.build(1000000)
    # 1 week, 4 days, 13 hours, 46 minutes, and 40.0 seconds

    duration_iso = duration.iso8601
    # P11DT13H46M40S

    ActiveSupport::Duration.parse(duration_iso)
    # 11 days, 13 hours, 46 minutes, and 40 seconds

    duration = ActiveSupport::Duration.build(604800)
    # 1 week

    duration_iso = duration.iso8601
    # P1W

    ActiveSupport::Duration.parse(duration_iso)
    # 1 week
    ```

    *Abhishek Sarkar*

*   Add block support to `ActiveSupport::Testing::TimeHelpers#travel_back`.

    *Tim Masliuchenko*

*   Update `ActiveSupport::Messages::Metadata#fresh?` to work for cookies with expiry set when
    `ActiveSupport.parse_json_times = true`.

    *Christian Gregg*

*   Support symbolic links for `content_path` in `ActiveSupport::EncryptedFile`.

    *Takumi Shotoku*

*   Improve `Range#===`, `Range#include?`, and `Range#cover?` to work with beginless (startless)
    and endless range targets.

    *Allen Hsu*, *Andrew Hodgkinson*

*   Don't use `Process#clock_gettime(CLOCK_THREAD_CPUTIME_ID)` on Solaris.

    *Iain Beeston*

*   Prevent `ActiveSupport::Duration.build(value)` from creating instances of
    `ActiveSupport::Duration` unless `value` is of type `Numeric`.

    Addresses the errant set of behaviours described in #37012 where
    `ActiveSupport::Duration` comparisons would fail confusingly
    or return unexpected results when comparing durations built from instances of `String`.

    Before:

        small_duration_from_string = ActiveSupport::Duration.build('9')
        large_duration_from_string = ActiveSupport::Duration.build('100000000000000')
        small_duration_from_int = ActiveSupport::Duration.build(9)

        large_duration_from_string > small_duration_from_string
        # => false

        small_duration_from_string == small_duration_from_int
        # => false

        small_duration_from_int < large_duration_from_string
        # => ArgumentError (comparison of ActiveSupport::Duration::Scalar with ActiveSupport::Duration failed)

        large_duration_from_string > small_duration_from_int
        # => ArgumentError (comparison of String with ActiveSupport::Duration failed)

    After:

        small_duration_from_string = ActiveSupport::Duration.build('9')
        # => TypeError (can't build an ActiveSupport::Duration from a String)

    *Alexei Emam*

*   Add `ActiveSupport::Cache::Store#delete_multi` method to delete multiple keys from the cache store.

    *Peter Zhu*

*   Support multiple arguments in `HashWithIndifferentAccess` for `merge` and `update` methods, to
    follow Ruby 2.6 addition.

    *Wojciech Wnętrzak*

*   Allow initializing `thread_mattr_*` attributes via `:default` option.

        class Scraper
          thread_mattr_reader :client, default: Api::Client.new
        end

    *Guilherme Mansur*

*   Add `compact_blank` for those times when you want to remove #blank? values from
    an Enumerable (also `compact_blank!` on Hash, Array, ActionController::Parameters).

    *Dana Sherson*

*   Make ActiveSupport::Logger Fiber-safe.

    Use `Fiber.current.__id__` in `ActiveSupport::Logger#local_level=` in order
    to make log level local to Ruby Fibers in addition to Threads.

    Example:

        logger = ActiveSupport::Logger.new(STDOUT)
        logger.level = 1
        puts "Main is debug? #{logger.debug?}"

        Fiber.new {
          logger.local_level = 0
          puts "Thread is debug? #{logger.debug?}"
        }.resume

        puts "Main is debug? #{logger.debug?}"

    Before:

        Main is debug? false
        Thread is debug? true
        Main is debug? true

    After:

        Main is debug? false
        Thread is debug? true
        Main is debug? false

    Fixes #36752.

    *Alexander Varnin*

*   Allow the `on_rotation` proc used when decrypting/verifying a message to be
    passed at the constructor level.

    Before:

        crypt = ActiveSupport::MessageEncryptor.new('long_secret')
        crypt.decrypt_and_verify(encrypted_message, on_rotation: proc { ... })
        crypt.decrypt_and_verify(another_encrypted_message, on_rotation: proc { ... })

    After:

        crypt = ActiveSupport::MessageEncryptor.new('long_secret', on_rotation: proc { ... })
        crypt.decrypt_and_verify(encrypted_message)
        crypt.decrypt_and_verify(another_encrypted_message)

    *Edouard Chin*

*   `delegate_missing_to` would raise a `DelegationError` if the object
    delegated to was `nil`. Now the `allow_nil` option has been added to enable
    the user to specify they want `nil` returned in this case.

    *Matthew Tanous*

*   `truncate` would return the original string if it was too short to be truncated
    and a frozen string if it were long enough to be truncated. Now truncate will
    consistently return an unfrozen string regardless. This behavior is consistent
    with `gsub` and `strip`.

    Before:

        'foobar'.truncate(5).frozen?
        # => true
        'foobar'.truncate(6).frozen?
        # => false

    After:

        'foobar'.truncate(5).frozen?
        # => false
        'foobar'.truncate(6).frozen?
        # => false
