1 Version 1.0.10 not yet released
3 * Fixed potential crashes during shutdown and (in rare conditions) when other
4 nodes disconnected from the VPN.

7 automatically fall back to TCP if direct UDP connection between nodes is not
10 * Allow configuration files with CRLF line endings to be read on UNIX.
12 * Disable old RSA keys when generating new ones.
14 * Many fixes in the path MTU discovery code.
16 * Tinc can now drop privileges and/or chroot itself.
18 * The TunnelServer code now just ignores information from clients instead of
21 * Improved performance on Windows by using the new ProcessPriority option and
22 by making the handling of packets received from the TAP-Win32 adapter more
25 * Code cleanups: tinc now follows the C99 standard, copyright headers have
26 been updated to include patch authors, checkpoint tracing and localisation
27 features have been removed.
29 * Support for (jailbroken) iPhone and iPod Touch has been added.
31 Thanks to Florian Forster, Grzegorz Dymarek and especially Michael Tokarev for
32 their contributions to this version of tinc.

36 * Fixed tinc as a service under Windows 2003.
38 * Fixed reading configuration files that do not end with a newline.

47 * Enable path MTU discovery by default.
49 * Fixed a memory leak that occured when connections were closed.
51 Thanks to Max Rijevski for his contributions to this version of tinc.
53 Version 1.0.8 May 16 2007
55 * Fixed some memory and resource leaks.
57 * Made network sockets non-blocking under Windows.
59 Thanks to Scott Lamb and "dnk" for their contributions to this version of tinc.

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

167 version 1.0pre7 Apr 7 2002

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