+*   Fixed a roundtrip problem with AS::SafeBuffer where primitive-like strings
+    will be dumped as primitives:
+
+    Before:
+
+       YAML.load ActiveSupport::SafeBuffer.new("Hello").to_yaml  # => "Hello"
+       YAML.load ActiveSupport::SafeBuffer.new("true").to_yaml   # => true
+       YAML.load ActiveSupport::SafeBuffer.new("false").to_yaml  # => false
+       YAML.load ActiveSupport::SafeBuffer.new("1").to_yaml      # => 1
+       YAML.load ActiveSupport::SafeBuffer.new("1.1").to_yaml    # => 1.1
+
+     After:
+
+       YAML.load ActiveSupport::SafeBuffer.new("Hello").to_yaml  # => "Hello"
+       YAML.load ActiveSupport::SafeBuffer.new("true").to_yaml   # => "true"
+       YAML.load ActiveSupport::SafeBuffer.new("false").to_yaml  # => "false"
+       YAML.load ActiveSupport::SafeBuffer.new("1").to_yaml      # => "1"
+       YAML.load ActiveSupport::SafeBuffer.new("1.1").to_yaml    # => "1.1"

+
+*   Enable number_to_percentage to keep the number's precision by allowing :precision to be nil
+
+    *Jack Xu*
+
+*   config_accessor became a private method, as with Ruby's attr_accessor.
+
+    *Akira Matsuda*
+
+*   `AS::Testing::TimeHelpers#travel_to` now changes `DateTime.now` as well as
+    `Time.now` and `Date.today`.
+
+    *Yuki Nishijima*
+
+*   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).
