38 * Allow building tinc without LZO and/or Zlib.
40 * Clamp MSS of TCP packets in both directions.
42 * Experimental StrictSubnets, Forwarding and DirectOnly options,
43 giving more control over information and packets received from/sent to other
46 * Ensure tinc never sends symbolic names for ports over the wire.
48 Version 1.0.12 Feb 3 2010
50 * Really allow fast roaming of hosts to other nodes in a switched VPN.
52 * Fixes missing or incorrect environment variables when calling host-up/down
53 and subnet-up/down scripts in some cases.

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

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

80 Version 1.0.10 Oct 18 2009
82 * Fixed potential crashes during shutdown and (in rare conditions) when other
83 nodes disconnected from the VPN.
85 * Improved NAT handling: tinc now copes with mangled port numbers, and will
86 automatically fall back to TCP if direct UDP connection between nodes is not
87 possible. The TCPOnly option should not have to be used anymore.
89 * Allow configuration files with CRLF line endings to be read on UNIX.
91 * Disable old RSA keys when generating new ones, and raise the default size of
92 new RSA keys to 2048 bits.

97 * Tinc can now drop privileges and/or chroot itself.
99 * The TunnelServer code now just ignores information from clients instead of
102 * Improved performance on Windows by using the new ProcessPriority option and

106 * Code cleanups: tinc now follows the C99 standard, copyright headers have
107 been updated to include patch authors, checkpoint tracing and localisation
108 features have been removed.

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

156 version 1.0.5 Nov 14 2006
158 * Lots of small fixes.

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