1 Version 1.0.8 May 16 2007
3 * Fixed some memory and resource leaks.
5 * Made network sockets non-blocking under Windows.
7 Version 1.0.7 Jan 5 2007

19 work anymore when part of the VPN had become disconnected from the rest.
21 version 1.0.5 Nov 14 2006
23 * Lots of small fixes.
25 * Broadcast packets no longer grow in size with each hop. This should
26 fix switch mode (again).

111 version 1.0pre7 Apr 7 2002
113 * Don't do blocking read()s when getting a signal.

125 * Non-blocking connects.
127 * Protocol broadcast messages can no longer go into an infinite loop.
129 * Graph algorithm updated to look harder for direct connections.
131 * Good support for routing IPv6 packets over the VPN. Works on Linux,
132 FreeBSD, possibly OpenBSD but not on Solaris.

137 * Optional compression of UDP connections using zlib.
139 * Optionally let UDP connections inherit TOS field of tunneled packets.

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