1 version 1.0.5 Nov 14 2006
5 * Broadcast packets no longer grow in size with each hop. This should
6 fix switch mode (again).

22 * Show error message when failing to write a PID file.

88 * Cleanup of source code.
91 version 1.0pre7 Apr 7 2002
93 * Don't do blocking read()s when getting a signal.

103 * Improvement of redundant links:
105 * Non-blocking connects.
107 * Protocol broadcast messages can no longer go into an infinite loop.
109 * Graph algorithm updated to look harder for direct connections.
111 * Good support for routing IPv6 packets over the VPN. Works on Linux,
112 FreeBSD, possibly OpenBSD but not on Solaris.
114 * Support for tunnels over IPv6 networks. Works on all supported
117 * Optional compression of UDP connections using zlib.

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