 ## RELEASE INFORMATION
 
-*Zend Framework 2.0.0rc5*
+*Zend Framework 2.0.0rc6*
 
 This is the fifth release candidate for 2.0.0. We will be releasing RCs
 on a weekly basis until we feel all critical issues are addressed. At
 this time, we anticipate few API changes before the stable release, and
 recommend testing your production applications against it.

-### UPDATES IN RC5
-
-- Zend\Db
-  - Now handles null values properly in execute mode.
-  - Added SqlSrv integration tests (prompted by a bug report of issues with
-    establishing a connection).
-- Zend\Form
-  - The FormButton helper now allows translation. However, to make this work, it
-    now requires that the label value is set in the element.
-  - Fixed an issue with the MultiCheckBox helper to ensure checked/unchecked
-    values are properly populated.
-  - The FormCheckbox view helper now requires that the element is a Checkbox
-    element; this is done to ensure the required options are available.
-- Zend\Log
-  - The table name constructor option is now optional, allowing you to pass it
-    in a configuration array.
-  - Now allows using DateTime with the Db Writer.
-- Zend\Http
-  - Added ability to set the SSL capath option.
-  - Added a check for the sslcapath being set if sslverifypeer is enabled when
-    first connecting to an SSL-enabled site; an exception is thrown if all
-    conditions are not met.
-  - PhpEnvironment\Request object now falls back to '/' for the base path if the
-    SCRIPT_FILENAME server variable is not present (true in PHP 5.4 web server
-    and several others).
-- Zend\I18n
-  - Caching translations now works.
+XX August 2012

+### UPDATES IN RC6

-- Zend\ServiceManager
-  - Now ensures that when $allowOverride is enabled that services registered
-    with the same name overwrite properly.
-- Zend\Validator
-  - The Uri validator is now listed in the validator plugin manager.
-  - The EmailAddress validator now allows setting custom error messages.
-- General fixes
-  - Removed all locations of error suppression remaining in the framework.

-    Zend\View\Helper\Url.
