17 * Clamp MSS of TCP packets in both directions.
19 * Experimental StrictSubnets, Forwarding and DirectOnly options,
20 giving more control over information and packets received from/sent to other

25 Version 1.0.12 Feb 3 2010
27 * Really allow fast roaming of hosts to other nodes in a switched VPN.
29 * Fixes missing or incorrect environment variables when calling host-up/down
30 and subnet-up/down scripts in some cases.
32 * Allow port to be specified in Address statements.
34 * Clamp MSS of TCP packets to the discovered path MTU.

40 Version 1.0.11 Nov 1 2009
42 * Fixed potential crash when the HUP signal is sent.
44 * Fixes handling of weighted Subnets in switch and hub modes, preventing

50 * Improvements to the PMTU discovery code, especially on Windows.
52 * Use UDP again in certain cases where 1.0.10 was too conservative and fell
53 back to TCP unnecessarily.

57 Version 1.0.10 Oct 18 2009
59 * Fixed potential crashes during shutdown and (in rare conditions) when other
60 nodes disconnected from the VPN.
62 * Improved NAT handling: tinc now copes with mangled port numbers, and will
63 automatically fall back to TCP if direct UDP connection between nodes is not
64 possible. The TCPOnly option should not have to be used anymore.
66 * Allow configuration files with CRLF line endings to be read on UNIX.
68 * Disable old RSA keys when generating new ones, and raise the default size of
69 new RSA keys to 2048 bits.
71 * Many fixes in the path MTU discovery code, especially when Compression is
74 * Tinc can now drop privileges and/or chroot itself.
76 * The TunnelServer code now just ignores information from clients instead of
79 * Improved performance on Windows by using the new ProcessPriority option and
80 by making the handling of packets received from the TAP-Win32 adapter more
83 * Code cleanups: tinc now follows the C99 standard, copyright headers have
84 been updated to include patch authors, checkpoint tracing and localisation
85 features have been removed.
87 * Support for (jailbroken) iPhone and iPod Touch has been added.
89 Thanks to Florian Forster, Grzegorz Dymarek and especially Michael Tokarev for
90 their contributions to this version of tinc.

133 version 1.0.5 Nov 14 2006
135 * Lots of small fixes.
137 * Broadcast packets no longer grow in size with each hop. This should

276 It looks like this might be the last release before 1.0.
279 version 1.0pre4 Jan 17 2001
281 * Updated documentation; the documentation now reflects the
282 configuration as it is.
284 * Some internal changes to make tinc scale better for large
285 networks, such as using AVL trees instead of linked lists for the
288 * RSA keys can be stored in separate files if needed. See the
289 documentation for more information.
291 * tinc has now been reported to run on Linux PowerPC and FreeBSD x86.
295 version 1.0pre3 Oct 31 2000
297 * The protocol has been redesigned, and although some details are
298 still under discussion, this is secure. Care has been taken to
299 resist most, if not all, attacks.
301 * Unfortunately this protocol is not compatible with earlier versions,
302 nor are earlier versions compatible with this version. Because the
303 older protocol has huge security flaws, we feel that not
304 implementing backwards compatibility is justified.
306 * Some data about the protocol:
308 * It uses public/private RSA keys for authentication (this is the
309 actual fix for the security hole).
311 * All cryptographic functions have been taken out of tinc, instead
312 it uses the OpenSSL library functions.
314 * Offers support for multiple subnets per tinc daemon.
316 * New is also the support for the universal tun/tap device. This
317 means better portability to FreeBSD and Solaris.
319 * tinc is tested to compile on Solaris, Linux x86, Linux alpha.
321 * tinc now uses the OpenSSL library for cryptographic operations.
322 More information on getting and installing OpenSSL is in the manual.
323 This also means that the GMP library is no longer required.
325 * Further, thanks to Enrique Zanardi, we have Spanish messages; Matias
326 Carrasco provided us with a Spanish translation of the manual.
329 What still needs to be done before 1.0:
331 * Documentation. Especially since the protocol has changed, and a lot
332 of configuration directives have been added.
337 version 1.0pre2 May 31 2000
339 * This version has been internationalized; and a Dutch translation has
342 * Two configuration variables have been added:
343 * VpnMask - the IP network mask for the entire VPN, not just our
344 subnet (as given by MyVirtualIP). The Redhat and Debian packages
345 use this variable in their system startup scripts, but it is
347 * Hostnames - if set to `yes', look up the names of IP addresses
348 trying to connect to us. Default set to `no', to prevent lockups
351 * The system startup scripts for Debian and Redhat use
352 /etc/tinc/nets.boot to find out which networks need to be started
355 * Fixes to prevent denial of service attacks by sending random data
356 after connecting (and even when the connection has been established),
357 either random garbage or just nonsensical protocol fields.
359 * tinc will retry to connect upon startup, does not quit if it doesn't
362 * Hosts that are disconnected implicitly if we lose a connection get
363 deleted from the internal list, to prevent hogging eachother with
364 add and delete requests when the connection is restored.
367 What still needs to be done before 1.0:
370 * Failover ConnectTo lines, try another one if the first doesn't work.
