Zope 2.11.2 (2008/10/24)
Bugs Fixed

    * Ensure that response header values cannot embed CRLF pairs,
      which violate the HTTP spec (RFC 2616).
    * Launchpad #282677: fixed implementation of guarded_map and provided
      tests and implementation for guarded_zip (RestrictedPython).
    * updated to ZODB 3.8.1
    * Lauchpad #143736,#271395: fixed AttributeError' on _ltid in TempStorage
    * AccessControl.ZopeGuards.guarded_import mapped some Unauthorized
      exceptions onto ImportErrors: don't do that! Also, removed mutable
      defaults from argument list, improved tests.
    * LP #281156: AccessControl.SecurityInfo.secureModule dropped
      ModuleSecurity for failed imports, obscuring later attempts to import
      the same broken module.
    * DateTime conversion of datetime objects with non-pytz
      tzinfo. Timezones() returns a copy of the timezone list (allows tests
      to run). (Backport of r89373 from trunk).
    * LP #253362: better dealing with malformed HTTP_ACCEPT_CHARSET headers
    * integrated Hotfix-2008-08-12
    * Launchpad #267545: DateTime(DateTime()) now preserves the correct hour
    * Launchpad #262313: respect the Expand macros when editing flag when
      editing a page template through the ZMI
