*** smtpmail

+**** smtpmail now uses encrypted connections (via STARTTLS) by default
+if the mail server supports them. This uses either built-in GnuTLS
+support, or the starttls.el library. Customize `smtpmail-stream-type'

**** The variable `smtpmail-auth-credentials' has been removed.
-That variable used to have the default value "~/.authinfo", in which

-of user names and passwords, that setting is now ignored; you will be
-prompted for the user name and the password, which will then be saved
-to ~/.authinfo. (To control where and how the credentials are stored,
-see the auth-source manual. You may want to change the auth-source
-preferences if you want to store the credentials encrypted, for
-instance.)

* Incompatible Lisp Changes in Emacs 24.1
