+What was new in ppp-2.3.
+************************
+
+* Demand-dialling. Pppd now has a mode where it will establish the
+network interface immediately when it starts, but not actually bring
+the link up until it sees some data to be sent. Look for the demand
+option description in the pppd man page. Demand-dialling is not
+supported under Ultrix or NeXTStep.
+
+* Idle timeout. Pppd will optionally terminate the link if no data
+packets are sent or received within a certain time interval.
+
+* Pppd now runs the /etc/ppp/auth-up script, if it exists, when the
+peer successfully authenticates itself, and /etc/ppp/auth-down when
+the connection is subsequently terminated. This can be useful for
+accounting purposes.
+
+* A new packet compression scheme, Deflate, has been implemented.
+This uses the same compression method as `gzip'. This method is free
+of patent or copyright restrictions, and it achieves better
+compression than BSD-Compress. It does consume more CPU cycles for
+compression than BSD-Compress, but this shouldn't be a problem for
+links running at 100kbit/s or less.
+
+* There is no code in this distribution which is covered by Brad
+Clements' restrictive copyright notice. The STREAMS modules for SunOS
+and OSF/1 have been rewritten, based on the Solaris 2 modules, which
+were written from scratch without any Clements code.
+
+* Pppstats has been reworked to clean up the output format somewhat.
+It also has a new -d option which displays data rate in kbyte/s for
+those columns which would normally display bytes.
+
+* 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.
