CHANGELOG.txt

 
 Drupal 7.18, xxxx-xx-xx (development version)
 -----------------------
+- Added link to the URL for running cron from outside the site to the Cron
+  settings page (UI change).
 - Fixed bug which prevented image styles from being reverted on PHP 5.4.
 - Made the default .htaccess rules protocol sensitive to improve security for
   sites which use HTTPS and redirect between "www" and non-"www" versions of

modules/system/system.admin.inc
