80 * Don't do blocking read()s when getting a signal.

90 * Improvement of redundant links:
92 * Non-blocking connects.
94 * Protocol broadcast messages can no longer go into an infinite loop.
96 * Graph algorithm updated to look harder for direct connections.
98 * Good support for routing IPv6 packets over the VPN. Works on Linux,
99 FreeBSD, possibly OpenBSD but not on Solaris.

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