1 Version 1.0.18 March 25 2012
3 * Fixed IPv6 in switch mode by turning off DecrementTTL by default.

24 * Disabling old RSA keys when generating new ones now also works properly on
27 Version 1.0.16 July 23 2011
29 * Fixed a performance issue with TCP communication under Windows.

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

100 * Improvements to the PMTU discovery code, especially on Windows.
102 * Use UDP again in certain cases where 1.0.10 was too conservative and fell
103 back to TCP unnecessarily.
105 * Allow fast roaming of hosts to other nodes in a switched VPN.
107 Version 1.0.10 Oct 18 2009
109 * Fixed potential crashes during shutdown and (in rare conditions) when other
110 nodes disconnected from the VPN.
112 * Improved NAT handling: tinc now copes with mangled port numbers, and will
113 automatically fall back to TCP if direct UDP connection between nodes is not
114 possible. The TCPOnly option should not have to be used anymore.
116 * Allow configuration files with CRLF line endings to be read on UNIX.
118 * Disable old RSA keys when generating new ones, and raise the default size of
119 new RSA keys to 2048 bits.

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

183 version 1.0.5 Nov 14 2006
185 * Lots of small fixes.

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