The variable `frame-alpha-lower-limit' defines a lower bound for the

+*** Emacs can now use `auth-source' for authentication.
+`smtpmail' and `url' (Tramp and Gnus also) use `auth-source' to obtain
+login names and passwords. The match, if found, is reported
+in *Messages* with the password blanked out.
+
** Internationalization changes
*** The Emacs character set is now a superset of Unicode.
accepts numbers in hash notation (e.g. #o21430 for octal, or #10r8984 for
decimal). It also accepts Unicode character names with completion.
+*** The `cyrillic-translit' input method supports many new characters.
+Common typographical characters available from Unicode were added to
+`cyrillic-translit': punctuation marks, accented characters, fractions,
+and others.

** Emacs now supports serial port access on GNU/Linux, Unix, and
Windows. The new command `serial-term' starts an interactive terminal
on a serial port. The serial port can be configured at runtime with
correctly in Emacs 22 and below. If you want to Gnus across different Emacs
versions, you may set `mm-auto-save-coding-system' to `emacs-mule'.
+*** Password are consistently loaded through `auth-source'
+Gnus can use `auth-source' for POP and IMAP passwords. Also see that
+`smtpmail' and `url' support `auth-source' for SMTP and HTTP/HTTPS/RSS
+authentication respectively.

** Help mode
*** New macro `with-help-window' should set up help windows better
than `with-output-to-temp-buffer' with `print-help-return-message'.
