28 * Allow building tinc without LZO and/or Zlib.
30 * Clamp MSS of TCP packets in both directions.
32 * Experimental StrictSubnets, Forwarding and DirectOnly options,
33 giving more control over information and packets received from/sent to other
36 * Ensure tinc never sends symbolic names for ports over the wire.
38 Version 1.0.12 Feb 3 2010
40 * Really allow fast roaming of hosts to other nodes in a switched VPN.
42 * Fixes missing or incorrect environment variables when calling host-up/down
43 and subnet-up/down scripts in some cases.
45 * Allow port to be specified in Address statements.
47 * Clamp MSS of TCP packets to the discovered path MTU.

53 Version 1.0.11 Nov 1 2009
55 * Fixed potential crash when the HUP signal is sent.

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

70 Version 1.0.10 Oct 18 2009
72 * Fixed potential crashes during shutdown and (in rare conditions) when other
73 nodes disconnected from the VPN.
75 * Improved NAT handling: tinc now copes with mangled port numbers, and will
76 automatically fall back to TCP if direct UDP connection between nodes is not
77 possible. The TCPOnly option should not have to be used anymore.
79 * Allow configuration files with CRLF line endings to be read on UNIX.
81 * Disable old RSA keys when generating new ones, and raise the default size of
82 new RSA keys to 2048 bits.
84 * Many fixes in the path MTU discovery code, especially when Compression is
87 * Tinc can now drop privileges and/or chroot itself.
89 * The TunnelServer code now just ignores information from clients instead of
92 * Improved performance on Windows by using the new ProcessPriority option and
93 by making the handling of packets received from the TAP-Win32 adapter more
96 * Code cleanups: tinc now follows the C99 standard, copyright headers have
97 been updated to include patch authors, checkpoint tracing and localisation
98 features have been removed.

102 Thanks to Florian Forster, Grzegorz Dymarek and especially Michael Tokarev for
103 their contributions to this version of tinc.

146 version 1.0.5 Nov 14 2006
148 * Lots of small fixes.
150 * Broadcast packets no longer grow in size with each hop. This should

238 version 1.0pre7 Apr 7 2002

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