1 Version 1.1-cvs Work in progress
3 * Use libevent to handle I/O events and timeouts.
5 * Use splay trees instead of AVL trees.
7 Version 1.0.12 Feb 3 2010
9 * Really allow fast roaming of hosts to other nodes in a switched VPN.
11 * Fixes missing or incorrect environment variables when calling host-up/down
12 and subnet-up/down scripts in some cases.
14 * Allow port to be specified in Address statements.
16 * Clamp MSS of TCP packets to the discovered path MTU.
18 * Let two nodes behind NAT learn each others current UDP address and port via
19 a third node, potentially allowing direct communications in a similar way to
22 Version 1.0.11 Nov 1 2009
24 * Fixed potential crash when the HUP signal is sent.
26 * Fixes handling of weighted Subnets in switch and hub modes, preventing
27 unnecessary broadcasts.
29 * Works around a MinGW bug that caused packets to Windows nodes to always be
32 * Improvements to the PMTU discovery code, especially on Windows.
34 * Use UDP again in certain cases where 1.0.10 was too conservative and fell
35 back to TCP unnecessarily.
37 * Allow fast roaming of hosts to other nodes in a switched VPN.
39 Version 1.0.10 Oct 18 2009
41 * Fixed potential crashes during shutdown and (in rare conditions) when other
42 nodes disconnected from the VPN.
44 * Improved NAT handling: tinc now copes with mangled port numbers, and will
45 automatically fall back to TCP if direct UDP connection between nodes is not
46 possible. The TCPOnly option should not have to be used anymore.
48 * Allow configuration files with CRLF line endings to be read on UNIX.
50 * Disable old RSA keys when generating new ones, and raise the default size of
51 new RSA keys to 2048 bits.
53 * Many fixes in the path MTU discovery code, especially when Compression is
56 * Tinc can now drop privileges and/or chroot itself.
58 * The TunnelServer code now just ignores information from clients instead of
61 * Improved performance on Windows by using the new ProcessPriority option and
62 by making the handling of packets received from the TAP-Win32 adapter more
65 * Code cleanups: tinc now follows the C99 standard, copyright headers have
66 been updated to include patch authors, checkpoint tracing and localisation
67 features have been removed.
69 * Support for (jailbroken) iPhone and iPod Touch has been added.
71 Thanks to Florian Forster, Grzegorz Dymarek and especially Michael Tokarev for
72 their contributions to this version of tinc.

76 * Fixed tinc as a service under Windows 2003.
78 * Fixed reading configuration files that do not end with a newline.
80 * Fixed crashes in situations where hostnames could not be resolved or hosts
81 would disconnect at the same time as session keys were exchanged.
83 * Improved default settings of tun and tap devices on BSD platforms.
85 * Make IPv6 sockets bind only to IPv6 on Linux.

108 Version 1.0.6 Dec 18 2006
110 * More flexible detection of the LZO libraries when compiling.

115 version 1.0.5 Nov 14 2006
117 * Lots of small fixes.
119 * Broadcast packets no longer grow in size with each hop. This should

207 version 1.0pre7 Apr 7 2002

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