The Point-to-Point Protocol (PPP) provides a standard way to establish
a network connection over a serial link. At present, this package
supports IP and the protocols layered above IP, such as TCP and UDP.

************************
+* 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.
