+Changes to configuration file format since 1.0pre5
+--------------------------------------------------
+
+Some configuration variables have different names now. Most notably "TapDevice"
+should be changed into "Device", and "Device" should be changed into
+"BindToDevice".
+
 Compatibility
 -------------
 
-Version 1.0.35 is compatible with 1.0pre8, 1.0 and later, but not with older
-versions of tinc. Note that since version 1.0.30, tinc requires all nodes in
-the VPN to be compiled with a version of LibreSSL or OpenSSL that supports the
-AES256 and SHA256 algorithms.
+Version 1.0.12 is compatible with 1.0pre8, 1.0 and later, but not with older
+versions of tinc.
 
 
 Requirements
 ------------
 
-The OpenSSL library is used for all cryptographic functions. You can find it at
-https://www.openssl.org/. You will need version 1.0.1 or later with support for
-AES256 and SHA256 enabled. If this library is not installed on your system, the
-configure script will fail.  The manual in doc/tinc.texi contains more detailed
-information on how to install this library. Alternatively, you may also use the
-LibreSSL library.
+Since 1.0pre3, we use OpenSSL for all cryptographic functions.  So you
+need to install this library first; grab it from
+http://www.openssl.org/.  You will need version 0.9.7 or later.  If
+this library is not installed on you system, configure will fail.  The
+manual in doc/tinc.texi contains more detailed information on how to
+install this library.
 
-The zlib library is used for optional compression. You can
-find it at https://zlib.net/. Because of a possible exploit in
-earlier versions we recommend that you download version 1.1.4 or later.
+Since 1.0pre6, the zlib library is used for optional compression. You need this
+library whether or not you plan to enable the compression. You can find it at
+http://www.gzip.org/zlib/. Because of a possible exploit in earlier versions we
+recommand that you download version 1.1.4 or later.
 
-The LZO library is also used for optional compression. You can
-find it at https://www.oberhumer.com/opensource/lzo/.
+Since 1.0, the lzo library is also used for optional compression. You need this

-  This package now provides native systemd service files, allowing multiple
-  instances of tinc to be managed. Existing networks listed in
-  /etc/tinc/nets.boot will be converted to service instances once during this
-  upgrade. Afterwards, you can enable and disable networks using:
-  
-    systemctl enable tinc@<netname>
-    systemctl disable tinc@<netname>
-  
-  If you do not have systemd installed, the SysV init script will continue to
-  work as usual. For more information, see README.Debian.

-tinc for Debian
----------------
-
-The manual for tinc is also available as info pages, type `info tinc'
-to read it.
-
-There are several ways in which tinc may be automatically started at boot:
-
-Systemd
--------
-
-Since 1.0.27-1, the tinc package comes with native systemd service files.
-To enable and start a net, call:
-
-systemctl enable tinc@<netname>
-systemctl start tinc@<netname>
-
-This will cause a tincd to be started which uses the configuration from
-/etc/tinc/<netname>, and also makes sure that it will be started next time your
-system boots.
-
-Apart from controlling individual instances, you can also start/stop/reload all
-enabled instances simultaneously by omitting @<netname>, for example:
-
-systemctl reload tinc
-
-Note that when you have systemd installed on your system, the file
-/etc/tinc/nets.boot will not be used anymore to automatically start tinc
-daemons. If the variable EXTRA is defined in /etc/default/tinc, it will be
-passed on to tinc. The variable LIMITS is however not used.
-
-The service files that come with this package start tinc unconditionally.
-However, tinc does support socket activation. If you wish to write a socket
-unit for tinc, use the ListenStream option to specify on which port(s) and
-address(es) tinc should listen.
-
-SysVinit
---------
-
-The system startup script for tinc, /etc/init.d/tinc, uses the file
-/etc/tinc/nets.boot to find out which networks have to be started. Use one
-netname per line. Lines starting with a # are ignored.
-
-/etc/network/interfaces
------------------------
-
-You can create a stanza in /etc/network/interfaces, and add a line with
-"tinc-net <netname>". This will cause a tincd to be started which uses the
-configuration from /etc/tinc/<netname>. You can use an inet static (with
-address and netmask options) or inet dhcp stanza, in which case the ifup will
-configure the VPN interface and you do not need to have a tinc-up script.
-
-The following options are also recognized and map directly to the corresponding
-command line options for tincd:
-
-tinc-config <directory>
-tinc-debug <level>
-tinc-mlock yes
-tinc-logfile <filename>
-tinc-pidfile <filename>
-tinc-chroot yes
-tinc-user <username>
-
-An example stanza:
-
-iface vpn inet static
-	address 192.168.2.42
-	netmask 255.255.0.0
-	tinc-net myvpn
-	tinc-debug 1
-	tinc-mlock yes
-	tinc-user nobody
-	tinc-pidfile /tmp/tinc.pid
-
-This will start a tinc daemon that reads its configuration from
-/etc/tinc/myvpn, logs at debug level 1, locks itself in RAM, runs as user
-nobody, and creates a network interface called "vpn". Ifup then sets the
-address and netmask on that interface.

- tinc is a daemon with which you can create a virtual private network
- (VPN). One daemon can handle multiple connections, so you can
- create an entire (moderately sized) VPN with only one daemon per
- participating computer.

-Severity: important
-
-Dear Guus,
-
-I have been using tinc since 2009 and it is great!
-
-When PMTUDiscovery=yes and Mode=switch, and if ipv6 is used inside
-tinc, the ICMPv6 "Packet Too Big" packets have incorrect checksums.
-It can be reproduced by `ping6 <host in tinc> -s 1800` and `tcpdump -i
-<tinc interface>`.  Consequently, the host ignores the tinc-generated
-ICMPv6 packets, PMTUDiscovery does not work and the connections freeze
-when data flows are big.
-
-I find the bug is gone if the function "inet_checksum" in route.c is
-not inlined, either by compiling tinc with "-O2
--fno-inline-functions", or apply a patch such as,
-
-diff --git a/src/route.c b/src/route.c

+/* alloca.c -- allocate automatically reclaimed memory
+   (Mostly) portable public-domain implementation -- D A Gwyn
+
+   This implementation of the PWB library alloca function,
+   which is used to allocate space off the run-time stack so
+   that it is automatically reclaimed upon procedure exit,
+   was inspired by discussions with J. Q. Johnson of Cornell.
+   J.Otto Tennant <jot@cray.com> contributed the Cray support.
+
+   There are some preprocessor constants that can
+   be defined when compiling for your specific system, for
+   improved efficiency; however, the defaults should be okay.
+
+   The general concept of this implementation is to keep
+   track of all alloca-allocated blocks, and reclaim any
+   that are found to be deeper in the stack than the current
+   invocation.  This heuristic does not reclaim storage as
+   soon as it becomes invalid, but it will do so eventually.
+
+   As a special case, alloca(0) reclaims storage without
+   allocating any.  It is a good idea to use alloca(0) in
+   your main control loop, etc. to force garbage collection.  */

-# SYNOPSIS
-#
-#   AX_APPEND_FLAG(FLAG, [FLAGS-VARIABLE])
-#
-# DESCRIPTION
-#
-#   FLAG is appended to the FLAGS-VARIABLE shell variable, with a space
-#   added in between.
-#
-#   If FLAGS-VARIABLE is not specified, the current language's flags (e.g.
-#   CFLAGS) is used.  FLAGS-VARIABLE is not changed if it already contains
-#   FLAG.  If FLAGS-VARIABLE is unset in the shell, it is set to exactly
-#   FLAG.
-#
-#   NOTE: Implementation based on AX_CFLAGS_GCC_OPTION.

-# DESCRIPTION
-#
-#   Try to find a compiler option that enables most reasonable warnings.

-#
-#   Currently this macro knows about the GCC, Solaris, Digital Unix, AIX,
-#   HP-UX, IRIX, NEC SX-5 (Super-UX 10), Cray J90 (Unicos 10.0.0.8), and
-#   Intel compilers.  For a given compiler, the Fortran flags are much more
-#   experimental than their C equivalents.

-#
-#   AX_REQUIRE_DEFINED is a simple helper for making sure other macros have
-#   been defined and thus are available for use.  This avoids random issues

-#   non-fatal:
-#
-#     ./configure: line 1673: AX_CFLAGS_WARN_ALL: command not found
-#
-#   It's like AC_REQUIRE except it doesn't expand the required macro.
