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 1.0.11 Nov 1 2009
9 * Fixed potential crash when the HUP signal is sent.
11 * Fixes handling of weighted Subnets in switch and hub modes, preventing
12 unnecessary broadcasts.
14 * Works around a MinGW bug that caused packets to Windows nodes to always be
17 * Improvements to the PMTU discovery code, especially on Windows.
19 * Use UDP again in certain cases where 1.0.10 was too conservative and fell
20 back to TCP unnecessarily.
22 * Allow fast roaming of hosts to other nodes in a switched VPN.
24 Version 1.0.10 Oct 18 2009
26 * Fixed potential crashes during shutdown and (in rare conditions) when other
27 nodes disconnected from the VPN.
29 * Improved NAT handling: tinc now copes with mangled port numbers, and will
30 automatically fall back to TCP if direct UDP connection between nodes is not
31 possible. The TCPOnly option should not have to be used anymore.
33 * Allow configuration files with CRLF line endings to be read on UNIX.
35 * Disable old RSA keys when generating new ones, and raise the default size of
36 new RSA keys to 2048 bits.
38 * Many fixes in the path MTU discovery code, especially when Compression is
41 * Tinc can now drop privileges and/or chroot itself.
43 * The TunnelServer code now just ignores information from clients instead of
46 * Improved performance on Windows by using the new ProcessPriority option and
47 by making the handling of packets received from the TAP-Win32 adapter more
50 * Code cleanups: tinc now follows the C99 standard, copyright headers have
51 been updated to include patch authors, checkpoint tracing and localisation
52 features have been removed.
54 * Support for (jailbroken) iPhone and iPod Touch has been added.
56 Thanks to Florian Forster, Grzegorz Dymarek and especially Michael Tokarev for
57 their contributions to this version of tinc.

100 version 1.0.5 Nov 14 2006
102 * Lots of small fixes.
104 * Broadcast packets no longer grow in size with each hop. This should

192 version 1.0pre7 Apr 7 2002

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