+## Rails 3.0.20 (unreleased)
+
+* Fixed JSON params parsing regression for non-object JSON content.
+
+## Rails 3.0.19 (Jan 8, 2013)
+
+* Strip nils from collections on JSON and XML posts. [CVE-2013-0155]
+
+## Rails 3.0.18 (Jan 2, 2013)
+
+* No changes.
+
+## Rails 3.0.17 (Aug 9, 2012)
+
+* There is an XSS vulnerability in the strip_tags helper in Ruby on Rails, the
+  helper doesn't correctly handle malformed html.  As a result an attacker can
+  execute arbitrary javascript through the use of specially crafted malformed
+  html.
+
+  *Marek from Nethemba (www.nethemba.com) & Santiago Pastorino*
+
+* When an "include_blank" value is supplied to the `select_tag` helper, the "include_blank" value is not escaped.  If untrusted data is not escaped, and is supplied as the prompt value, there is a potential for XSS attacks.
+  Vulnerable code will look something like this:
+    select_tag("name", options, :include_blank => UNTRUSTED_INPUT)
+
+  *Santiago Pastorino*
+
+## Rails 3.0.16 (Jul 26, 2012)
+
+* Do not convert digest auth strings to symbols. CVE-2012-3424
+
+## Rails 3.0.14 (Jun 12, 2012)
+
+*   nil is removed from array parameter values
+
+    CVE-2012-2694
+
+* Rails 3.0.13 (May 31, 2012)
+
+* Strip null bytes from Location header
+
+* load the encoding converter to work around [ruby-core:41556] when switching
+  encodings
+
+* Avoid inspecting the whole route set, closes #1525
+
+* whitelist protocols for auto_link
+
+* Strip [nil] from parameters hash. Thanks to Ben Murphy for reporting this!
+  CVE-2012-2660
+
+*Rails 3.0.12 (unreleased)*
+
+* Fix using `tranlate` helper with a html translation which uses the `:count` option for
+  pluralization.
+
+  *Jon Leighton*
+
+*Rails 3.0.11 (unreleased)*
+
+* Fix XSS security vulnerability in the `translate` helper method. When using interpolation
+  in combination with HTML-safe translations, the interpolated input would not get HTML
+  escaped. *GH 3664*
+
+  Before:
+
+      translate('foo_html', :something => '<script>') # => "...<script>..."
+
+  After:
+
+      translate('foo_html', :something => '<script>') # => "...&lt;script&gt;..."
+
+  *Sergey Nartimov*
+
+* Implement a workaround for a bug in ruby-1.9.3p0 where an error would be
+  raised while attempting to convert a template from one encoding to another.
+
+  Please see http://redmine.ruby-lang.org/issues/5564 for details of the bug.
+
+  The workaround is to load all conversions into memory ahead of time, and will
+  only happen if the ruby version is exactly 1.9.3p0. The hope is obviously
+  that the underlying problem will be resolved in the next patchlevel release
+  of 1.9.3.
+
+* Fix assert_select_email to work on multipart and non-multipart emails as the method stopped working correctly in Rails 3.x due to changes in the new mail gem.
+
+* Fix url_for when passed a hash to prevent additional options (eg. :host, :protocol) from being added to the hash after calling it.
+
+
+*Rails 3.0.10 (August 16, 2011)*
+
+* Fixes an issue where cache sweepers with only after filters would have no
+controller object, it would raise undefined method controller_name for nil [jeroenj]
+
+* Ensure status codes are logged when exceptions are raised.
+
+* Subclasses of OutputBuffer are respected.
+
+* Fixed ActionView::FormOptionsHelper#select with :multiple => false
+
+* Avoid extra call to Cache#read in case of a fragment cache hit
+
+*Rails 3.0.9 (June 16, 2011)*
+
+* json_escape will now return a SafeBuffer string if it receives SafeBuffer string [tenderlove]
+
+* Make sure escape_js returns SafeBuffer string if it receives SafeBuffer string [Prem Sichanugrist]
+
+* Fix text helpers to work correctly with the new SafeBuffer restriction [Paul Gallagher, Arun Agrawal, Prem Sichanugrist]
+
+
+*Rails 3.0.8 (June 7, 2011)*
+
+* It is prohibited to perform a in-place SafeBuffer mutation [tenderlove]
+
+  The old behavior of SafeBuffer allowed you to mutate string in place via
+  method like `sub!`. These methods can add unsafe strings to a safe buffer,
+  and the safe buffer will continue to be marked as safe.
+
+  An example problem would be something like this:
+
+    <%= link_to('hello world', @user).sub!(/hello/, params[:xss])  %>
+
+  In the above example, an untrusted string (`params[:xss]`) is added to the
+  safe buffer returned by `link_to`, and the untrusted content is successfully
+  sent to the client without being escaped.  To prevent this from happening
+  `sub!` and other similar methods will now raise an exception when they are called on a safe buffer.
+
+  In addition to the in-place versions, some of the versions of these methods which return a copy of the string will incorrectly mark strings as safe. For example:
+
+     <%= link_to('hello world', @user).sub(/hello/, params[:xss]) %>
+
+  The new versions will now ensure that *all* strings returned by these methods on safe buffers are marked unsafe.
+
+  You can read more about this change in http://groups.google.com/group/rubyonrails-security/browse_thread/thread/2e516e7acc96c4fb
+
+* Fixed github issue #342 with asset paths and relative roots.
+
+
+*Rails 3.0.7 (April 18, 2011)*
+
+*No changes.
+
+
+*Rails 3.0.6 (April 5, 2011)
+
+* Fixed XSS vulnerability in `auto_link`.  `auto_link` no longer marks input as
+  html safe.  Please make sure that calls to auto_link() are wrapped in a
+  sanitize(), or a raw() depending on the type of input passed to auto_link().
+  For example:
+
+    <%= sanitize(auto_link(some_user_input)) %>
+
+  Thanks to Torben Schulz for reporting this.  The fix can be found here:
+  61ee3449674c591747db95f9b3472c5c3bd9e84d
+
+* Fixes the output of `rake routes` to be correctly match to the behavior of the application, as the regular expression used to match the path is greedy and won't capture the format part by default [Prem Sichanugrist]
+
+* Fixes an issue with number_to_human when converting values which are less than 1 but greater than -1 [Josh Kalderimis]
+
+* Sensitive query string parameters (specified in config.filter_parameters) will now be filtered out from the request paths in the log file. [Prem Sichanugrist, fxn]
+
+* URL parameters which return nil for to_param are now removed from the query string [Andrew White]
+
+* Don't allow i18n to change the minor version, version now set to ~> 0.5.0 [Santiago Pastorino]
+
+* Make TranslationHelper#translate use the :rescue_format option in I18n 0.5.0 [Sven Fuchs]
+
+* Fix regression: javascript_include_tag shouldn't raise if you register an expansion key with nil or [] value [Santiago Pastorino]
+
+* Fix Action caching bug where an action that has a non-cacheable response always renders a nil response body. It now correctly renders the response body. [Cheah Chu Yeow]
