o Upgrading from a version prior to 1.6.9:
Starting with sudo 1.6.9, if an OS supports a modular authentication
* A new flag, -n, may be used to indicate that sudo should not
prompt the user for a password and, instead, exit with an error
if authentication is required.
+
+ * If sudo needs to prompt for a password and it is unable to disable
+ echo (and no askpass program is defined), it will refuse to run
+ unless the "visiblepw" Defaults option has been specified.
+
+ * Prior to version 1.7.0, hitting enter/return at the Password: prompt
+ would exit sudo. In sudo 1.7.0 and beyond, this is treated as
+ an empty password. To exit sudo, the user must press ^C or ^D
+ at the prompt.
