+What was new in ppp-2.3.11.
+***************************
+
+* Support for Solaris 8 has been added, including support for
+  replumbing and IPV6.
+
+* The Solaris `snoop' utility should now work on ppp interfaces.
+
+* New hooks have been added - pap_logout_hook, ip_up_hook, and
+  ip_down_hook.
+
+* A new `passprompt' plugin is included, thanks to Alan Curry, which
+  makes it possible for pppd to call an external program to get the
+  PAP password to send to the peer.
+
+* The error messages for the situation where authentication is
+  required because the system has a default route have been improved.
+
+* There is a new connect_delay option which specifies how long pppd
+  should pause after the connect script finishes.  Previously this
+  delay was fixed at 1 second.  (This delay terminates as soon as pppd
+  sees a valid PPP frame from the peer.)
+
+* The `hide-password' option is now the default, and there is a new
+  `show-password' option to enable the printing of password strings in
+  the debug output.
+
+* A fairly complete list of the names of PPP protocols has been added
+  so that when pppd rejects a frame because its protocol is not
+  supported, it can print the name of the unsupported protocol.
+
+* Synchronous serial lines are supported under Linux 2.3.x.
+
+* The bug where pppd would not recognize a modem hangup under Linux
+  2.3.x kernels has been fixed.
+
+
+What was new in ppp-2.3.10.
+***************************
+
+* Pppd now supports `plugins', which are pieces of code (packaged as
+  shared libraries) which can be loaded into pppd at runtime and which
+  can affect its behaviour.  The intention is that plugins provide a
+  way for people to customize the behaviour of pppd for their own
+  needs without needing to change the base pppd source.  I have added
+  some hooks into pppd (places where pppd will call a function
+  pointer, if non-zero, to replace some of pppd's code) and I will be
+  receptive to suggestions about places to add more hooks.  Plugins
+  are supported under Linux and Solaris at present.
+
+* We have a new maintainer for the Solaris port, Adi Masputra of Sun
+  Microsystems, and he has updated the Solaris port so that it should
+  work on 64-bit machines under Solaris 7 and later.
+
+* Pppd now has an `allow-ip' option, which takes an argument which is
+  an IP address (or subnet) which peers are permitted to use without
+  authenticating themselves.  The argument takes the same form as each
+  element of the allowed IP address list in the secrets files.  The
+  allow-ip option is privileged and may be specified multiple times.
+  Using the allow-ip option should be cleaner than putting a line like
+  `"" * "" address' in /etc/ppp/pap-secrets.
+
+* Chat can now substitute environment variables into the script.  This
+  is enabled by the -E flag.  (Thanks to Andreas Arens for the patch.)
+
+* If the PAP username and password from the peer contains unprintable
+  characters, they will be translated to a printable form before
+  looking in the pap-secrets file.  Characters >= 0x80 are translated
+  to a M- form, and characters from 0 to 0x1f (and 0x7f as well) are
+  translated to a ^X form.  If this change causes you grief, let me
+  know what would be a better translation.  It appears that some peers
+  send nulls or other control characters in their usernames and
+  passwords.
+
+* Pppd has new `ktune' and `noktune' options, which enable/disable
+  it to change kernel settings as appropriate.  This is only
+  implemented under Linux, and requires the /proc filesystem to be
+  mounted.  Under Linux, with the ktune option, pppd will enable IP
+  forwarding in the kernel if the proxyarp option is used, and will
+  enable the dynamic IP address kernel option in demand mode if the
+  local IP address changes.
+
+* Pppd no longer requires a remote address to be specified for demand
+  dialling.  If none is specified, it will use a default value of
+  10.112.112.112+unit_number.  (It will not propose this default to
+  the peer.)
+
+* The default holdoff is now 0 if no connect script is given.
+
+* The IPV6 code from Tommi Komulainen, which I unfortunately only
+  partially merged in to ppp-2.3.9, has been fixed and updated.
+
+* The linux compilation glitches should be fixed now.
+
+
+What was new in ppp-2.3.9.
+**************************
+
+* Support for the new generic PPP layer under development for the
+  Linux kernel.
+
+* You can now place extra options to apply to specific users at the
+  end of the line with their password in the pap-secrets or
+  chap-secrets file, separated from the IP address(es) with a "--"
+  separator.  These options are parsed after the peer is authenticated
+  but before network protocol (IPCP, IPXCP) or CCP negotiation
+  commences.
+
+* Pppd will apply the holdoff period if the link was terminated by the
+  peer.  It doesn't apply it if the link was terminated because the
+  local pppd thought it was idle.
+
+* Synchronous support for Solaris has been added, thanks to John
+  Morrison, and for FreeBSD, thanks to Paul Fulghum.
+
+* IPV6 support has been merged in, from Tommi Komulainen.  At the
+  moment it only supports Linux and it is not tested by me.
+
+* The `nodefaultip' option can be used in demand mode to say that pppd
+  should not suggest its local IP address to the peer.
+
+* The `init' option has been added; this causes pppd to run a script
+  to initialize the serial device (e.g. by sending an init string to
+  the modem).  Unlike the connect option, this can be used in a
+  dial-in situation.  (Thanks to Tobias Ringstrom.)
+
+* There is a new `logfile' option to send log messages to a file as
+  well as syslog.
+
+* There is a new, privileged `linkname' option which sets a logical
+  name for the link.  Pppd will create a /var/run/ppp-<linkname>.pid
+  file containing its process ID.
+
+* There is a new `maxfail' option which specifies how many consecutive
+  failed connection attempts are permitted before pppd will exit.  The
+  default value is 10, and 0 means infinity. :-)
+
+* Sundry bugs fixed.
+
+
+What was new in ppp-2.3.8.
+**************************
+
+* The exit status of pppd will now indicate whether the link was
+  successfully established, or if not, what error was encountered.
+
+* Pppd has two new options: fdlog <n> will send log messages to file
+  descriptor <n> instead of standard output, and nofdlog will stop log
+  messages from being sent to any file descriptor (they will still be
+  sent to syslog).  Pppd now will not send log messages to a file
+  descriptor if the serial port is open on that file descriptor.
+
+* Pppd sets an environment variable called PPPLOGNAME for scripts that
+  it runs, indicating the login name of the user who invoked pppd.
+
+* Pppd sets environment variables CONNECT_TIME, BYTES_SENT and
+  BYTES_RCVD for the ip-down and auth-down scripts indicating the
+  statistics for the connection just terminated.  (CONNECT_TIME is in
+  seconds.)
+
+* If the user has the serial device open on standard input and
+  specifies a symbolic link to the serial device on the command line,
+  pppd will detect this and behave correctly (i.e. not detach from its
+  controlling terminal).  Furthermore, if the serial port is open for
+  reading and writing on standard input, pppd will assume that it is
+  locked by its invoker and not lock it itself.
+
+* Chat now has a feature where if a string to be sent begins with an
+  at sign (@), the rest of the string is taken as the name of a file
+  (regular file or named pipe), and the actual string to send is taken
+  from that file.
+
+* Support for FreeBSD-2.2.8 and 3.0 has been added, thanks to Paul
+  Fulghum.
+
+* The Tru64 (aka Digital Unix aka OSF/1) port has been updated.
+
+* The system panics on Solaris SMP systems related to PPP connections
+  being established and terminated should no longer occur.
+
+* Fixed quite a few bugs.
+
+
+What was new in ppp-2.3.7.
+**************************
+
+* Pppd can now automatically allocate itself a pseudo-tty to use as
+  the serial device.  This has made three new options possible:
+
+  - `pty script' will run `script' with its standard input and output
+    connected to the master side of the pty.  For example:
+	pppd pty 'ssh -t server.my.net pppd'
+    is a basic command for setting up a PPP link (tunnel) over ssh.
+    (In practice you may need to specify other options such as IP
+    addresses, etc.)
+
+  - `notty' tells pppd to communicate over its standard input and
+    output, which do not have to be a terminal device.
+
+  - `record filename' tells pppd to record all of the characters sent
+    and received over the serial device to a file called `filename'.
+    The data is recorded in a tagged format with timestamps, which can
+    be printed in a readable form with the pppdump program, which is
+    included in this distribution.
+
+* Pppd now logs the connect time and number of bytes sent and received
+  (at the level of the serial device) when the connection is
+  terminated.
+
+* If you use the updetach or nodetach option, pppd will print its
+  messages to standard output as well as logging them with syslog
+  (provided of course pppd isn't using its standard input or output as
+  its serial device).
+
+* There is a new `privgroup groupname' option (a privileged option).
+  If the user running pppd is in group `groupname', s/he can use
+  privileged options without restriction.
+
+* There is a new `receive-all' option, which causes pppd to accept all
+  control characters, even the ones that the peer should be escaping
+  (i.e. the receive asyncmap is 0).  This is useful with some buggy
+  peers.
+
+* The default asyncmap is now 0.
+
+* There is a new `sync' option, currently only implemented under
+  Linux, which allows pppd to run on synchronous HDLC devices.
+
+* If a value for the device name or for the connect, disconnect,
+  welcome or pty option is given in a privileged option file
+  (i.e. /etc/ppp/options or a file loaded with the `call' option), it
+  cannot be overridden by a non-privileged user.
+
+* Many bugs have been fixed, notably:
+  - signals are not blocked unnecessarily, as they were in 2.3.6.
+  - the usepeerdns option should work now.
+  - the SPEED environment variable for scripts is set correctly.
+  - the /etc/ppp/auth-down script is not run until auth-up completes.
+  - the device is opened as root if it is the device on standard
+    input.
+  - pppd doesn't die with the ioctl(PPPIOCSASYNCMAP) error under linux
+    if a hangup occurs at the wrong time.
+
+* Some error messages have been changed to be clearer (I hope :-)
+
+
+What was new in ppp-2.3.6.
+**************************
+
+* Pppd now opens the tty device as the user (rather than as root) if
+  the device name was given by the user, i.e. on the command line or
+  in the ~/.ppprc file.  If the device name was given in
+  /etc/ppp/options or in a file loaded with the `call' option, the
+  device is opened as root.
+
+* The default behaviour of pppd is now to let a peer which has not
+  authenticated itself (e.g. your ISP) use any IP address to which the
+  system does not already have a route.  (This is currently only
+  supported under Linux, Solaris and Digital Unix; on the other
+  systems, the peer must now authenticate itself unless the noauth
+  option is used.)
+
+* Added new option `usepeerdns', thanks to Nick Walker
+  <nickwalker@email.com>.  If the peer supplies DNS addresses, these
+  will be written to /etc/ppp/resolv.conf.  The ip-up script can then
+  be used to add these addresses to /etc/resolv.conf if desired (see
+  the ip-up.local.add and ip-down.local.add files in the scripts
+  directory).
+
+* The Solaris ppp driver should now work correctly on SMP systems.
+
+* Minor corrections so that the code can compile under Solaris 7,
+  and under Linux with glibc-2.1.
+
+* The Linux kernel driver has been restructured for improved
+  performance.
+
+* Pppd now won't start the ip-down script until the ip-up script has
+  finished.
+
+
+What was new in ppp-2.3.5.
+**************************
+
+* Minor corrections to the Digital UNIX and NetBSD ports.
+
+* A workaround to avoid tickling a bug in the `se' serial port driver
+on Sun PCI Ultra machines running Solaris.
+
+* Fixed a bug in the negotiation of the Microsoft WINS server address
+option.
+
+* Fixed a bug in the Linux port where it would fail for kernel
+versions above 2.1.99.
+
+
+What was new in ppp-2.3.4.
+**************************
+
+* The NeXT port has been updated, thanks to Steve Perkins.
+
+* ppp-2.3.4 compiles and works under Solaris 2.6, using either gcc or
+cc.
+
+* With the Solaris, SVR4 and SunOS ports, you can control the choice
+of C compiler, C compiler options, and installation directories by
+editing the svr4/Makedefs or sunos4/Makedefs file.
+
+* Until now, we have been using the number 24 to identify Deflate
+compression in the CCP negotiations, which was the number in the draft
+RFC describing Deflate.  The number actually assigned to Deflate is
+26.  The code has been changed to use 26, but to allow the use of 24
+for now for backwards compatibility.  (This can be disabled with the
+`nodeflatedraft' option to pppd.)
+
+* Fixed some bugs in the linux driver and deflate compressor which
+were causing compression problems, including corrupting long
+incompressible packets sometimes.
+
+* Fixes to the PAM and shadow password support in pppd, from Al
+Longyear and others.
+
+* Pppd now sets some environment variables for scripts it invokes
+(ip-up/down, auth-ip/down), giving information about the connection.
+The variables it sets are PEERNAME, IPLOCAL, IPREMOTE, UID, DEVICE,
+SPEED, and IFNAME.
+
+* Pppd now has an `updetach' option, which will cause it to detach
+from its controlling terminal once the link has come up (i.e. once it
+is available for IP traffic).
+
+
+What was new in ppp-2.3.3.
+**************************
+
+* Fixed compilation problems under SunOS.
+
+* Fixed a bug introduced into chat in 2.3.2, and compilation problems
+introduced into the MS-CHAP implementation in 2.3.2.
+
+* The linux kernel driver has been updated for recent 2.1-series
+kernel changes, and it now will ask kerneld to load compression
+modules when required, if the kernel is configured to support kerneld.
+
+* Pppd should now compile correctly under linux on systems with glibc.
+
+
+What was new in ppp-2.3.2.
+**************************
+
+* In 2.3.1, I made a change which was intended to make pppd able to
+detect loss of CD during or immediately after the connection script
+runs.  Unfortunately, this had the side-effect that the connection
+script wouldn't work at all on some systems.  This change has been
+reversed.
+
+* Fix compilation problems in the Linux kernel driver.
+
+
+What was new in ppp-2.3.1.
+**************************
+
+* Enhancements to chat, thanks to Francis Demierre.  Chat can now
+accept comments in the chat script file, and has new SAY, HANGUP,
+CLR_ABORT and CLR_REPORT keywords.
+
+* Fixed a bug which causes 2.3.0 to crash Solaris systems.
+
+* Bug-fixes and restructuring of the Linux kernel driver.
+
+* The holdoff behaviour of pppd has been changed slightly: now, if
+the link comes up for IP (or other network protocol) traffic, we
+consider that the link has been successfully established, and don't
+enforce the holdoff period after the link goes down.
+
+* Pppd should now correctly wait for CD (carrier detect) from the
+modem, even when the serial port initially had CLOCAL set, and it
+should also detect loss of CD during or immediately after the
+connection script runs.
+
+* Under linux, pppd will work with older 2.2.0* version kernel
+drivers, although demand-dialling is not supported with them.
+
+* Minor bugfixes for pppd.
+
+
+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.
