 Bug Fixes
 ---------
 
-- Removed support for null-bytes in the path when making a request for a file
-  against a static_view. Whille null-bytes are allowed by the HTTP
-  specification, due to the handling of null-bytes potentially leading to
-  security vulnerabilities it is no longer supported.
-
-  This fixes a security vulnerability that is present due to a bug in Python
-  3.11.0 through 3.11.4, thereby allowing the unintended disclosure of an
-  ``index.html`` one directory up from the static views path.
-
-  Thanks to Masashi Yamane of LAC Co., Ltd for reporting this issue.
-
 - Fix issues where permissions may be checked on exception views. This is not
   supposed to happen in normal circumstances.
