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

55 * Fixed tinc as a service under Windows 2003.
57 * Fixed reading configuration files that do not end with a newline.
59 * Fixed crashes in situations where hostnames could not be resolved or hosts
60 would disconnect at the same time as session keys were exchanged.
62 * Improved default settings of tun and tap devices on BSD platforms.
64 * Make IPv6 sockets bind only to IPv6 on Linux.
66 * Enable path MTU discovery by default.
68 * Fixed a memory leak that occured when connections were closed.

74 * Fixed some memory and resource leaks.
76 * Made network sockets non-blocking under Windows.
78 Thanks to Scott Lamb and "dnk" for their contributions to this version of tinc.
80 Version 1.0.7 Jan 5 2007

94 version 1.0.5 Nov 14 2006
96 * Lots of small fixes.
98 * Broadcast packets no longer grow in size with each hop. This should
99 fix switch mode (again).

179 conditions and improve scalability.
181 * Generalized broadcasting and forwarding of protocol messages.
183 * Cleanup of source code.
186 version 1.0pre7 Apr 7 2002
188 * Don't do blocking read()s when getting a signal.

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