 ## Rails 4.0.0 (unreleased) ##
 
+*   Extract `ActiveSupport::Testing::Performance` into https://github.com/rails/rails-perftest
+    You can add the gem to your Gemfile to keep using performance tests.
+
+        gem 'rails-perftest'

+*   Hash.from_xml raises when it encounters type="symbol" or type="yaml".
+    Use Hash.from_trusted_xml to parse this XML.
+
+    CVE-2013-0156
+
+    *Jeremy Kemper*
+
+*   Deprecate `assert_present` and `assert_blank` in favor of
+    `assert object.blank?` and `assert object.present?`
+
+    *Yves Senn*
+
+*   Change `String#to_date` to use `Date.parse`. This gives more consistent error
+    messages and allows the use of partial dates.
+
+        "gibberish".to_date => Argument Error: invalid date
+        "3rd Feb".to_date => Sun, 03 Feb 2013
+
+    *Kelly Stannard*
+
+*   It's now possible to compare `Date`, `DateTime`, `Time` and `TimeWithZone`
+    with `Infinity`. This allows to create date/time ranges with one infinite bound.
+    Example:
+
+        range = Range.new(Date.today, Float::INFINITY)
+
+    Also it's possible to check inclusion of date/time in range with conversion.
+
+        range.include?(Time.now + 1.year)     # => true
+        range.include?(DateTime.now + 1.year) # => true
+
+    *Alexander Grebennik*
+
+*   Remove meaningless `ActiveSupport::FrozenObjectError`, which was just an alias of `RuntimeError`.
+
+    *Akira Matsuda*
+
+*   Introduce `assert_not` to replace warty `assert !foo`.  *Jeremy Kemper*
+
 *   Prevent `Callbacks#set_callback` from setting the same callback twice.
