+*   Fix file descriptor being leaked on each call to `Kernel.silence_stream`.
+
+    *Mario Visic*
+
+*   Ensure `config.i18n.enforce_available_locales` is set before any other
+    configuration option.
+
+    *Yves Senn*
+
+*   Added `Date#all_week/month/quarter/year` for generating date ranges.
+
+    *Dmitriy Meremyanin*
+
+*   Add `Time.zone.yesterday` and `Time.zone.tomorrow`. These follow the
+    behavior of Ruby's `Date.yesterday` and `Date.tomorrow` but return localized
+    versions, similar to how `Time.zone.today` has returned a localized version
+    of `Date.today`.
+
+    *Colin Bartlett*
+
+*   Show valid keys when `assert_valid_keys` raises an exception, and show the
+    wrong value as it was entered.
+
+    *Gonzalo Rodríguez-Baltanás Díaz*
+
+*   Both `cattr_*` and `mattr_*` method definitions now live in `active_support/core_ext/module/attribute_accessors`.
+
+    Requires to `active_support/core_ext/class/attribute_accessors` are
+    deprecated and will be removed in Ruby on Rails 4.2.
+
+    *Genadi Samokovarov*
+
+*   Deprecated `Numeric#{ago,until,since,from_now}`, the user is expected to explicitly
+    convert the value into an AS::Duration, i.e. `5.ago` => `5.seconds.ago`
+
+    This will help to catch subtle bugs like:
+
+        def recent?(days = 3)
+          self.created_at >= days.ago
+        end
+
+    The above code would check if the model is created within the last 3 **seconds**.
+
+    In the future, `Numeric#{ago,until,since,from_now}` should be removed completely,
+    or throw some sort of errors to indicate there are no implicit conversion from
+    Numeric to AS::Duration.
+
+    *Godfrey Chan*
+
+*   Requires JSON gem version 1.7.7 or above due to a security issue in older versions.
+
+    *Godfrey Chan*
+
+*   Removed the old pure-Ruby JSON encoder and switched to a new encoder based on the built-in JSON
+    gem.
+
+    Support for encoding `BigDecimal` as a JSON number, as well as defining custom `encode_json`
+    methods to control the JSON output has been **removed from core**. The new encoder will always
+    encode BigDecimals as `String`s and ignore any custom `encode_json` methods.
+
+    The old encoder has been extracted into the `activesupport-json_encoder` gem. Installing that
+    gem will bring back the ability to encode `BigDecimal`s as numbers as well as `encode_json`
+    support.
+
+    Setting the related configuration `ActiveSupport.encode_big_decimal_as_string` without the
+    `activesupport-json_encoder` gem installed will raise an error.
+
+    *Godfrey Chan*
+
 *   Add `ActiveSupport::Testing::TimeHelpers#travel` and `#travel_to`. These methods change current
     time to the given time or time difference by stubbing `Time.now` and `Date.today` to return the
     time or date after the difference calculation, or the time or date that got passed into the
-    method respectively. These methods also accept a block, which will return current time back to
-    its original state at the end of the block.
