1 Version 1.0.13 Apr 11 2010
3 * Allow building tinc without LZO and/or Zlib.
5 * Clamp MSS of TCP packets in both directions.
7 * Experimental StrictSubnets, Forwarding and DirectOnly options,
8 giving more control over information and packets received from/sent to other
11 * Ensure tinc never sends symbolic names for ports over the wire.
13 Version 1.0.12 Feb 3 2010
15 * Really allow fast roaming of hosts to other nodes in a switched VPN.
17 * Fixes missing or incorrect environment variables when calling host-up/down
18 and subnet-up/down scripts in some cases.
20 * Allow port to be specified in Address statements.
22 * Clamp MSS of TCP packets to the discovered path MTU.
24 * Let two nodes behind NAT learn each others current UDP address and port via
25 a third node, potentially allowing direct communications in a similar way to
28 Version 1.0.11 Nov 1 2009
30 * Fixed potential crash when the HUP signal is sent.
32 * Fixes handling of weighted Subnets in switch and hub modes, preventing
33 unnecessary broadcasts.
35 * Works around a MinGW bug that caused packets to Windows nodes to always be
38 * Improvements to the PMTU discovery code, especially on Windows.
40 * Use UDP again in certain cases where 1.0.10 was too conservative and fell
41 back to TCP unnecessarily.
43 * Allow fast roaming of hosts to other nodes in a switched VPN.
45 Version 1.0.10 Oct 18 2009
47 * Fixed potential crashes during shutdown and (in rare conditions) when other
48 nodes disconnected from the VPN.
50 * Improved NAT handling: tinc now copes with mangled port numbers, and will
51 automatically fall back to TCP if direct UDP connection between nodes is not
52 possible. The TCPOnly option should not have to be used anymore.
54 * Allow configuration files with CRLF line endings to be read on UNIX.
56 * Disable old RSA keys when generating new ones, and raise the default size of
57 new RSA keys to 2048 bits.
59 * Many fixes in the path MTU discovery code, especially when Compression is
62 * Tinc can now drop privileges and/or chroot itself.
64 * The TunnelServer code now just ignores information from clients instead of
67 * Improved performance on Windows by using the new ProcessPriority option and
68 by making the handling of packets received from the TAP-Win32 adapter more
71 * Code cleanups: tinc now follows the C99 standard, copyright headers have
72 been updated to include patch authors, checkpoint tracing and localisation
73 features have been removed.
75 * Support for (jailbroken) iPhone and iPod Touch has been added.
77 Thanks to Florian Forster, Grzegorz Dymarek and especially Michael Tokarev for
78 their contributions to this version of tinc.
80 Version 1.0.9 Dec 26 2008
82 * Fixed tinc as a service under Windows 2003.
84 * Fixed reading configuration files that do not end with a newline.
86 * Fixed crashes in situations where hostnames could not be resolved or hosts
87 would disconnect at the same time as session keys were exchanged.
89 * Improved default settings of tun and tap devices on BSD platforms.
91 * Make IPv6 sockets bind only to IPv6 on Linux.

121 version 1.0.5 Nov 14 2006
123 * Lots of small fixes.
125 * Broadcast packets no longer grow in size with each hop. This should

213 version 1.0pre7 Apr 7 2002

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