46 * Allow building tinc without LZO and/or Zlib.
48 * Clamp MSS of TCP packets in both directions.
50 * Experimental StrictSubnets, Forwarding and DirectOnly options,
51 giving more control over information and packets received from/sent to other
54 * Ensure tinc never sends symbolic names for ports over the wire.
56 Version 1.0.12 Feb 3 2010
58 * Really allow fast roaming of hosts to other nodes in a switched VPN.
60 * Fixes missing or incorrect environment variables when calling host-up/down
61 and subnet-up/down scripts in some cases.
63 * Allow port to be specified in Address statements.
65 * Clamp MSS of TCP packets to the discovered path MTU.

71 Version 1.0.11 Nov 1 2009
73 * Fixed potential crash when the HUP signal is sent.
75 * Fixes handling of weighted Subnets in switch and hub modes, preventing
76 unnecessary broadcasts.

81 * Improvements to the PMTU discovery code, especially on Windows.
83 * Use UDP again in certain cases where 1.0.10 was too conservative and fell
84 back to TCP unnecessarily.
86 * Allow fast roaming of hosts to other nodes in a switched VPN.
88 Version 1.0.10 Oct 18 2009
90 * Fixed potential crashes during shutdown and (in rare conditions) when other
91 nodes disconnected from the VPN.
93 * Improved NAT handling: tinc now copes with mangled port numbers, and will
94 automatically fall back to TCP if direct UDP connection between nodes is not
95 possible. The TCPOnly option should not have to be used anymore.
97 * Allow configuration files with CRLF line endings to be read on UNIX.
99 * Disable old RSA keys when generating new ones, and raise the default size of
100 new RSA keys to 2048 bits.
102 * Many fixes in the path MTU discovery code, especially when Compression is
105 * Tinc can now drop privileges and/or chroot itself.
107 * The TunnelServer code now just ignores information from clients instead of
110 * Improved performance on Windows by using the new ProcessPriority option and
111 by making the handling of packets received from the TAP-Win32 adapter more
114 * Code cleanups: tinc now follows the C99 standard, copyright headers have
115 been updated to include patch authors, checkpoint tracing and localisation
116 features have been removed.
118 * Support for (jailbroken) iPhone and iPod Touch has been added.
120 Thanks to Florian Forster, Grzegorz Dymarek and especially Michael Tokarev for
121 their contributions to this version of tinc.

164 version 1.0.5 Nov 14 2006
166 * Lots of small fixes.

256 version 1.0pre7 Apr 7 2002

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