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

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

42 * Fixed tinc as a service under Windows 2003.
44 * Fixed reading configuration files that do not end with a newline.
46 * Fixed crashes in situations where hostnames could not be resolved or hosts
47 would disconnect at the same time as session keys were exchanged.

53 * Enable path MTU discovery by default.
55 * Fixed a memory leak that occured when connections were closed.
57 Thanks to Max Rijevski for his contributions to this version of tinc.
59 Version 1.0.8 May 16 2007
61 * Fixed some memory and resource leaks.
63 * Made network sockets non-blocking under Windows.
65 Thanks to Scott Lamb and "dnk" for their contributions to this version of tinc.
67 Version 1.0.7 Jan 5 2007

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

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