+*   Add `file_fixture` to `ActiveSupport::TestCase`.
+    It provides a simple mechanism to access sample files in your test cases.
+
+    By default file fixtures are stored in `test/fixtures/files`. This can be
+    configured per test-case using the `file_fixture_path` class attribute.
+
+    *Yves Senn*
+
+*   Return value of yielded block in `File.atomic_write`.
+
+    *Ian Ker-Seymer*
+
+*   Duplicate frozen array when assigning it to a HashWithIndifferentAccess so
+    that it doesn't raise a `RuntimeError` when calling `map!` on it in `convert_value`.
+
+    Fixes #18550.
+
+    *Aditya Kapoor*
+
+*   Add missing time zone definitions for Russian Federation and sync them
+    with `zone.tab` file from tzdata version 2014j (latest).
+
+    *Andrey Novikov*
+
+*   Add `SecureRandom.base58` for generation of random base58 strings.
+
+    *Matthew Draper*, *Guillermo Iguaran*
+
+*   Add `#prev_day` and `#next_day` counterparts to `#yesterday` and
+    `#tomorrow` for `Date`, `Time`, and `DateTime`.
+
+    *George Claghorn*
+
+*   Add `same_time` option to `#next_week` and `#prev_week` for `Date`, `Time`,
+    and `DateTime`.
+
+    *George Claghorn*
+
+*   Add `#on_weekend?`, `#next_weekday`, `#prev_weekday` methods to `Date`,
+    `Time`, and `DateTime`.
+
+    `#on_weekend?` returns true if the receiving date/time falls on a Saturday
+    or Sunday.
+
+    `#next_weekday` returns a new date/time representing the next day that does
+    not fall on a Saturday or Sunday.
+
+    `#prev_weekday` returns a new date/time representing the previous day that
+    does not fall on a Saturday or Sunday.

+
+*   Change the way in which callback chains can be halted.
+
+    The preferred method to halt a callback chain from now on is to explicitly
+    `throw(:abort)`.
+    In the past, returning `false` in an ActiveSupport callback had the side
+    effect of halting the callback chain. This is not recommended anymore and,
+    depending on the value of
+    `Callbacks::CallbackChain.halt_and_display_warning_on_return_false`, will
+    either not work at all or display a deprecation warning.
+
+*   Add Callbacks::CallbackChain.halt_and_display_warning_on_return_false
+
+    Setting `Callbacks::CallbackChain.halt_and_display_warning_on_return_false`
+    to true will let an app support the deprecated way of halting callback
+    chains by returning `false`.
+
+    Setting the value to false will tell the app to ignore any `false` value
+    returned by callbacks, and only halt the chain upon `throw(:abort)`.
+
+    The value can also be set with the Rails configuration option
+    `config.active_support.halt_callback_chains_on_return_false`.
+
+    When the configuration option is missing, its value is `true`, so older apps
+    ported to Rails 5.0 will not break (but display a deprecation warning).
+    For new Rails 5.0 apps, its value is set to `false` in an initializer, so
+    these apps will support the new behavior by default.

+
+*   Changes arguments and default value of CallbackChain's :terminator option
+
+    Chains of callbacks defined without an explicit `:terminator` option will
+    now be halted as soon as a `before_` callback throws `:abort`.
+
+    Chains of callbacks defined with a `:terminator` option will maintain their
+    existing behavior of halting as soon as a `before_` callback matches the
+    terminator's expectation.
