+*2.3.2 [Final] (March 15, 2009)*
+
+* Fixed that redirection would just log the options, not the final url (which lead to "Redirected to #<Post:0x23150b8>") [DHH]
+
+* Added ability to pass in :public => true to fresh_when, stale?, and expires_in to make the request proxy cachable #2095 [Gregg Pollack]
+
+* Fixed that passing a custom form builder would be forwarded to nested fields_for calls #2023 [Eloy Duran/Nate Wiger]
+
+* Form option helpers now support disabled option tags and the use of lambdas for selecting/disabling option tags from collections #837 [Tekin]
 
 * Added partial scoping to TranslationHelper#translate, so if you call translate(".foo") from the people/index.html.erb template, you'll actually be calling I18n.translate("people.index.foo") [DHH]
