+* Pppd options beginning with - or + have been renamed, e.g. -ip
+became noip, +chap became require-chap, etc. The old options are
+still accepted for compatibility but may be removed in future.
+
+* Pppd now has some options (such as the new `noauth' option) which
+can only be specified if it is being run by root, or in an
+"privileged" options file: /etc/ppp/options or an options file in the
+/etc/ppp/peers directory. There is a new "call" option to read
+options from a file in /etc/ppp/peers, making it possible for non-root
+users to make unauthenticated connections, but only to certain trusted
+peers. My intention is to make the `auth' option the default in a
+future release.
+
+* Several minor new features have been added to pppd, including the
+maxconnect and welcome options. Pppd will now terminate the
+connection when there are no network control protocols running. The
+allowed IP address(es) field in the secrets files can now specify
+subnets (with a notation like 123.45.67.89/24) and addresses which are
+not acceptable (put a ! on the front).
+
+* Numerous bugs have been fixed (no doubt some have been introduced :-)
+Thanks to those who reported bugs in ppp-2.2.
