1 Version 1.0.7 Jan 5 2007
3 * Fixed a bug that caused slow network speeds on Windows.
5 * Fixed a bug that caused tinc unable to write packets to the tun device on
8 Version 1.0.6 Dec 18 2006
10 * More flexible detection of the LZO libraries when compiling.
12 * Fixed a bug where broadcasts in switch and hub modes sometimes would not
13 work anymore when part of the VPN had become disconnected from the rest.
15 version 1.0.5 Nov 14 2006
17 * Lots of small fixes.
19 * Broadcast packets no longer grow in size with each hop. This should
20 fix switch mode (again).
22 * Generic host-up and host-down scripts.
24 * Optionally dump graph in graphviz format to a file or a script.
26 * Support LZO 2.0 and later.

36 * Show error message when failing to write a PID file.
38 * Ignore spaces at end of lines in config files.
40 * Fix handling of late packets.

45 * Handle IPv6 on Solaris tun devices.
47 * Allow tinc to work properly under Windows XP SP2.
49 * Allow VLAN tagged Ethernet frames in switch and hub mode.

78 version 1.0 Aug 4 2003
80 * Lots of small bugfixes and code cleanups.
82 * Throughput doubled and latency reduced.
84 * Added support for LZO compression.
86 * No need to set MAC address or disable ARP anymore.
88 * Added support for Windows 2000 and XP, both natively and in a Cygwin
91 version 1.0pre8 Sep 16 2002
93 * More fixes for subnets with prefixlength undivisible by 8.
95 * Added support for NetBSD and MacOS/X.
97 * Switched from undirected graphs to directed graphs to avoid certain race
98 conditions and improve scalability.
100 * Generalized broadcasting and forwarding of protocol messages.
102 * Cleanup of source code.
105 version 1.0pre7 Apr 7 2002
107 * Don't do blocking read()s when getting a signal.
109 * Remove RSA key checking code, since it sometimes thinks perfectly good RSA
112 * Fix handling of subnets when prefixlength isn't divisible by 8.
115 version 1.0pre6 Mar 27 2002
117 * Improvement of redundant links:
119 * Non-blocking connects.
121 * Protocol broadcast messages can no longer go into an infinite loop.
123 * Graph algorithm updated to look harder for direct connections.
125 * Good support for routing IPv6 packets over the VPN. Works on Linux,
126 FreeBSD, possibly OpenBSD but not on Solaris.
128 * Support for tunnels over IPv6 networks. Works on all supported
131 * Optional compression of UDP connections using zlib.
133 * Optionally let UDP connections inherit TOS field of tunneled packets.

142 * Added sequence number and optional message authentication code to
145 * Configurable encryption cipher and digest algorithms.
147 * More robust handling of dis- and reconnects.
149 * Added a "switch" and a "hub" mode to allow bridging setups.
151 * Preliminary support for routing of IPv6 packets.
153 * Supports Linux, FreeBSD, OpenBSD and Solaris.
156 It looks like this might be the last release before 1.0.
159 version 1.0pre4 Jan 17 2001
161 * Updated documentation; the documentation now reflects the
162 configuration as it is.
164 * Some internal changes to make tinc scale better for large
165 networks, such as using AVL trees instead of linked lists for the
168 * RSA keys can be stored in separate files if needed. See the
169 documentation for more information.
171 * tinc has now been reported to run on Linux PowerPC and FreeBSD x86.
175 version 1.0pre3 Oct 31 2000
177 * The protocol has been redesigned, and although some details are
178 still under discussion, this is secure. Care has been taken to
179 resist most, if not all, attacks.
181 * Unfortunately this protocol is not compatible with earlier versions,
182 nor are earlier versions compatible with this version. Because the
183 older protocol has huge security flaws, we feel that not
184 implementing backwards compatibility is justified.
186 * Some data about the protocol:
188 * It uses public/private RSA keys for authentication (this is the
189 actual fix for the security hole).
191 * All cryptographic functions have been taken out of tinc, instead
192 it uses the OpenSSL library functions.
194 * Offers support for multiple subnets per tinc daemon.
196 * New is also the support for the universal tun/tap device. This
197 means better portability to FreeBSD and Solaris.
199 * tinc is tested to compile on Solaris, Linux x86, Linux alpha.
201 * tinc now uses the OpenSSL library for cryptographic operations.
202 More information on getting and installing OpenSSL is in the manual.
203 This also means that the GMP library is no longer required.
205 * Further, thanks to Enrique Zanardi, we have Spanish messages; Matias
206 Carrasco provided us with a Spanish translation of the manual.
209 What still needs to be done before 1.0:
211 * Documentation. Especially since the protocol has changed, and a lot
212 of configuration directives have been added.
217 version 1.0pre2 May 31 2000
219 * This version has been internationalized; and a Dutch translation has
222 * Two configuration variables have been added:
223 * VpnMask - the IP network mask for the entire VPN, not just our
224 subnet (as given by MyVirtualIP). The Redhat and Debian packages
225 use this variable in their system startup scripts, but it is
227 * Hostnames - if set to `yes', look up the names of IP addresses
228 trying to connect to us. Default set to `no', to prevent lockups
231 * The system startup scripts for Debian and Redhat use
232 /etc/tinc/nets.boot to find out which networks need to be started
235 * Fixes to prevent denial of service attacks by sending random data
236 after connecting (and even when the connection has been established),
237 either random garbage or just nonsensical protocol fields.
239 * tinc will retry to connect upon startup, does not quit if it doesn't
242 * Hosts that are disconnected implicitly if we lose a connection get
243 deleted from the internal list, to prevent hogging eachother with
244 add and delete requests when the connection is restored.
247 What still needs to be done before 1.0:
250 * Failover ConnectTo lines, try another one if the first doesn't work.
