+# 2.4.7 (2012-02-01)
+
+## Overview
+
+ * Security: Cross-site scripting (XSS) on text transformations in templates
+ * Security: Cross-site scripting (XSS) related to page titles in the CMS
+ 
+## Upgrading Notes ##
+
+### Security: Cross-site scripting (XSS) on text transformations in templates
+
+The default casting for `Text` and `Varchar` database field classes usually auto-escapes
+field values when they are inserted into a template. For some text transformations
+on those fields, this wasn't correctly applied. The following methods are affected:
+
+ * `AbsoluteLinks()`,
+ * `BigSummary()`,
+ * `ContextSummary()`,
+ * `EscapeXML()`,
+ * `FirstParagraph()`,
+ * `FirstSentence()`,
+ * `Initial()`,
+ * `LimitCharacters()`,
+ * `LimitSentences()`,
+ * `LimitWordCount()`,
+ * `LimitWordCountXML()`,
+ * `Lower()`
+ * `LowerCase()`
+ * `NoHTML()`,
+ * `Summary()`,
+ * `Upper()`
+ * `UpperCase()`
+ * `URL()`
+
+ If you have used any of these transformations with untrusted values
+ (e.g. from a user-submitted form), please consider updating.
+ More info about SilverStripe's casting logic is available in the "[security](../topics/security)" documentation.
+
+### Security: Cross-site scripting (XSS) related to page titles in the CMS
+
+The page title data wasn't escaped correctly in the `SilverStripeNavigator`
+as well as the updated page title in the CMS tree after saving.
