56 * Allow building tinc without LZO and/or Zlib.
58 * Clamp MSS of TCP packets in both directions.
60 * Experimental StrictSubnets, Forwarding and DirectOnly options,
61 giving more control over information and packets received from/sent to other
64 * Ensure tinc never sends symbolic names for ports over the wire.
66 Version 1.0.12 Feb 3 2010
68 * Really allow fast roaming of hosts to other nodes in a switched VPN.
70 * Fixes missing or incorrect environment variables when calling host-up/down

91 * Improvements to the PMTU discovery code, especially on Windows.
93 * Use UDP again in certain cases where 1.0.10 was too conservative and fell

98 Version 1.0.10 Oct 18 2009
100 * Fixed potential crashes during shutdown and (in rare conditions) when other
101 nodes disconnected from the VPN.
103 * Improved NAT handling: tinc now copes with mangled port numbers, and will
104 automatically fall back to TCP if direct UDP connection between nodes is not
105 possible. The TCPOnly option should not have to be used anymore.
107 * Allow configuration files with CRLF line endings to be read on UNIX.
109 * Disable old RSA keys when generating new ones, and raise the default size of
110 new RSA keys to 2048 bits.

115 * Tinc can now drop privileges and/or chroot itself.
117 * The TunnelServer code now just ignores information from clients instead of
120 * Improved performance on Windows by using the new ProcessPriority option and
121 by making the handling of packets received from the TAP-Win32 adapter more
124 * Code cleanups: tinc now follows the C99 standard, copyright headers have
125 been updated to include patch authors, checkpoint tracing and localisation
126 features have been removed.
128 * Support for (jailbroken) iPhone and iPod Touch has been added.
130 Thanks to Florian Forster, Grzegorz Dymarek and especially Michael Tokarev for
131 their contributions to this version of tinc.

174 version 1.0.5 Nov 14 2006
176 * Lots of small fixes.

310 * Added a "switch" and a "hub" mode to allow bridging setups.
312 * Preliminary support for routing of IPv6 packets.
314 * Supports Linux, FreeBSD, OpenBSD and Solaris.
317 It looks like this might be the last release before 1.0.
320 version 1.0pre4 Jan 17 2001
322 * Updated documentation; the documentation now reflects the
323 configuration as it is.
325 * Some internal changes to make tinc scale better for large
326 networks, such as using AVL trees instead of linked lists for the
329 * RSA keys can be stored in separate files if needed. See the
330 documentation for more information.
332 * tinc has now been reported to run on Linux PowerPC and FreeBSD x86.
336 version 1.0pre3 Oct 31 2000
338 * The protocol has been redesigned, and although some details are
339 still under discussion, this is secure. Care has been taken to
340 resist most, if not all, attacks.
342 * Unfortunately this protocol is not compatible with earlier versions,
343 nor are earlier versions compatible with this version. Because the
344 older protocol has huge security flaws, we feel that not
345 implementing backwards compatibility is justified.
347 * Some data about the protocol:
349 * It uses public/private RSA keys for authentication (this is the
350 actual fix for the security hole).
352 * All cryptographic functions have been taken out of tinc, instead
353 it uses the OpenSSL library functions.
355 * Offers support for multiple subnets per tinc daemon.
357 * New is also the support for the universal tun/tap device. This
358 means better portability to FreeBSD and Solaris.
360 * tinc is tested to compile on Solaris, Linux x86, Linux alpha.
362 * tinc now uses the OpenSSL library for cryptographic operations.
363 More information on getting and installing OpenSSL is in the manual.
364 This also means that the GMP library is no longer required.
366 * Further, thanks to Enrique Zanardi, we have Spanish messages; Matias
367 Carrasco provided us with a Spanish translation of the manual.
370 What still needs to be done before 1.0:
372 * Documentation. Especially since the protocol has changed, and a lot
373 of configuration directives have been added.
378 version 1.0pre2 May 31 2000
380 * This version has been internationalized; and a Dutch translation has
383 * Two configuration variables have been added:
384 * VpnMask - the IP network mask for the entire VPN, not just our
385 subnet (as given by MyVirtualIP). The Redhat and Debian packages
386 use this variable in their system startup scripts, but it is
388 * Hostnames - if set to `yes', look up the names of IP addresses
389 trying to connect to us. Default set to `no', to prevent lockups
392 * The system startup scripts for Debian and Redhat use
393 /etc/tinc/nets.boot to find out which networks need to be started
396 * Fixes to prevent denial of service attacks by sending random data
397 after connecting (and even when the connection has been established),
398 either random garbage or just nonsensical protocol fields.
400 * tinc will retry to connect upon startup, does not quit if it doesn't
403 * Hosts that are disconnected implicitly if we lose a connection get
404 deleted from the internal list, to prevent hogging eachother with
405 add and delete requests when the connection is restored.
408 What still needs to be done before 1.0:
411 * Failover ConnectTo lines, try another one if the first doesn't work.
