1 Version 1.0.10 Oct 18 2009
3 * Fixed potential crashes during shutdown and (in rare conditions) when other
4 nodes disconnected from the VPN.
6 * Improved NAT handling: tinc now copes with mangled port numbers, and will
7 automatically fall back to TCP if direct UDP connection between nodes is not
8 possible. The TCPOnly option should not have to be used anymore.
10 * Allow configuration files with CRLF line endings to be read on UNIX.
12 * Disable old RSA keys when generating new ones, and raise the default size of
13 new RSA keys to 2048 bits.
15 * Many fixes in the path MTU discovery code, especially when Compression is
18 * Tinc can now drop privileges and/or chroot itself.
20 * The TunnelServer code now just ignores information from clients instead of
23 * Improved performance on Windows by using the new ProcessPriority option and
24 by making the handling of packets received from the TAP-Win32 adapter more
27 * Code cleanups: tinc now follows the C99 standard, copyright headers have
28 been updated to include patch authors, checkpoint tracing and localisation
29 features have been removed.
31 * Support for (jailbroken) iPhone and iPod Touch has been added.
33 Thanks to Florian Forster, Grzegorz Dymarek and especially Michael Tokarev for
34 their contributions to this version of tinc.
36 Version 1.0.9 Dec 26 2008
38 * Fixed tinc as a service under Windows 2003.
40 * Fixed reading configuration files that do not end with a newline.
42 * Fixed crashes in situations where hostnames could not be resolved or hosts
43 would disconnect at the same time as session keys were exchanged.
45 * Improved default settings of tun and tap devices on BSD platforms.
47 * Make IPv6 sockets bind only to IPv6 on Linux.
49 * Enable path MTU discovery by default.
51 * Fixed a memory leak that occured when connections were closed.
53 Thanks to Max Rijevski for his contributions to this version of tinc.
55 Version 1.0.8 May 16 2007
57 * Fixed some memory and resource leaks.
59 * Made network sockets non-blocking under Windows.
61 Thanks to Scott Lamb and "dnk" for their contributions to this version of tinc.
63 Version 1.0.7 Jan 5 2007

77 version 1.0.5 Nov 14 2006
79 * Lots of small fixes.
81 * Broadcast packets no longer grow in size with each hop. This should
82 fix switch mode (again).

162 conditions and improve scalability.
164 * Generalized broadcasting and forwarding of protocol messages.
166 * Cleanup of source code.
169 version 1.0pre7 Apr 7 2002
171 * Don't do blocking read()s when getting a signal.

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