+* Pppd will now run /etc/ppp/ip-pre-up, if it exists, after creating
+ the ppp interface and configuring its IP addresses but before
+ bringing it up. This can be used, for example, for adding firewall
+ rules for the interface.
+
+* Lots of bugs fixed, particularly in the area of demand-dialled and
+ persistent connections.
+
+
+What was new in ppp-2.4.3.
+**************************
+
+* The configure script now accepts --prefix and --sysconfdir options.
+ These default to /usr/local and /etc. If you want pppd put in
+ /usr/sbin as before, use ./configure --prefix=/usr.
+
+* Doing `make install' no longer puts example configuration files in
+ /etc/ppp. Use `make install-etcppp' if you want that.
+
+* The code has been updated to work with version 0.8.3 of libpcap.
+ Unfortunately the libpcap maintainers removed support for the
+ "inbound" and "outbound" keywords on PPP links, meaning that if you
+ link pppd with libpcap-0.8.3, you can't use those keywords in the
+ active-filter and pass-filter expressions. The support has been
+ reinstated in the CVS version and should be in future libpcap
+ releases. If you need the in/outbound keywords, use a later release
+ than 0.8.3, or get the CVS version from http://www.tcpdump.org.
+
+* There is a new option, child-timeout, which sets the length of time
+ that pppd will wait for child processes (such as the command
+ specified with the pty option) to exit before exiting itself. It
+ defaults to 5 seconds. After the timeout, pppd will send a SIGTERM
+ to any remaining child processes and exit. A value of 0 means no
+ timeout.
+
+* Various bugs have been fixed, including some CBCP packet parsing
+ bugs that could lead to the peer being able to crash pppd if CBCP
+ support is enabled.
+
+* Various fixes and enhancements to the radius and rp-pppoe plugins
+ have been added.
+
+* There is a new winbind plugin, from Andrew Bartlet of the Samba
+ team, which provides the ability to authenticate the peer against an
+ NT domain controller using MS-CHAP or MS-CHAPV2.
+
+* There is a new pppoatm plugin, by various authors, sent in by David
+ Woodhouse.
+
+* The multilink code has been substantially reworked. The first pppd
+ for a bundle still controls the ppp interface, but it doesn't exit
+ until all the links in the bundle have terminated. If the first
+ pppd is signalled to exit, it signals all the other pppds
+ controlling links in the bundle.
+
+* The TDB code has been updated to the latest version. This should
+ eliminate the problem that some people have seen where the database
+ file (/var/run/pppd.tdb) keeps on growing. Unfortunately, however,
+ the new code uses an incompatible database format. For this reason,
+ pppd now uses /var/run/pppd2.tdb as the database filename.
+
+
+What was new in ppp-2.4.2.
+**************************
+
+* The CHAP code has been rewritten. Pppd now has support for MS-CHAP
+ V1 and V2 authentication, both as server and client. The new CHAP
+ code is cleaner than the old code and avoids some copyright problems
+ that existed in the old code.
+
+* MPPE (Microsoft Point-to-Point Encryption) support has been added,
+ although the current implementation shouldn't be considered
+ completely secure. (There is no assurance that the current code
+ won't ever transmit an unencrypted packet.)
+
+* James Carlson's implementation of the Extensible Authentication
+ Protocol (EAP) has been added.
+
+* Support for the Encryption Control Protocol (ECP) has been added.
+
+* Some new plug-ins have been included:
+ - A plug-in for kernel-mode PPPoE (PPP over Ethernet)
+ - A plug-in for supplying the PAP password over a pipe from another
+ process
+ - A plug-in for authenticating using a Radius server.
+
+* Updates and bug-fixes for the Solaris port.
+
+* The CBCP (Call Back Control Protocol) code has been updated. There
+ are new options `remotenumber' and `allow-number'.
+
+* Extra hooks for plugins to use have been added.
+
+* There is now a `maxoctets' option, which causes pppd to terminate
+ the link once the number of bytes passed on the link exceeds a given
+ value.
+
+* There are now options to control whether pppd can use the IPCP
+ IP-Address and IP-Addresses options: `ipcp-no-address' and
+ `ipcp-no-addresses'.
+
+* Fixed several bugs, including potential buffer overflows in chat.
+
+
+What was new in ppp-2.4.1.
+**************************
+
+* Pppd can now print out the set of options that are in effect. The
+ new `dump' option causes pppd to print out the option values after
+ option parsing is complete. The `dryrun' option causes pppd to
+ print the options and then exit.
+
+* The option parsing code has been fixed so that options in the
+ per-tty options file are parsed correctly, and don't override values
+ from the command line in most cases.
+
+* The plugin option now looks in /usr/lib/pppd/<pppd-version> (for
+ example, /usr/lib/pppd/2.4.1b1) for shared objects for plugins if
+ there is no slash in the plugin name.
+
+* When loading a plugin, pppd will now check the version of pppd for
+ which the plugin was compiled, and refuse to load it if it is
+ different to pppd's version string. To enable this, the plugin
+ source needs to #include "pppd.h" and have a line saying:
+ char pppd_version[] = VERSION;
+
+* There is a bug in zlib, discovered by James Carlson, which can cause
+ kernel memory corruption if Deflate is used with the lowest setting,
+ 8. As a workaround pppd will now insist on using at least 9.
+
+* Pppd should compile on Solaris and SunOS again.
+
+* Pppd should now set the MTU correctly on demand-dialled interfaces.
+
+
+What was new in ppp-2.4.0.
