The TCPOnly option should not have to be used anymore. + + * Allow configuration files with CRLF line endings to be read on UNIX. + + * Disable old RSA keys when generating new ones, and raise the default size of + new RSA keys to 2048 bits. + + * Many fixes in the path MTU discovery code, especially when Compression is + being used. + + * Tinc can now drop privileges and/or chroot itself. + + * The TunnelServer code now just ignores information from clients instead of + disconnecting them. + + * Improved performance on Windows by using the new ProcessPriority option and + by making the handling of packets received from the TAP-Win32 adapter more + efficient. + + * Code cleanups: tinc now follows the C99 standard, copyright headers have + been updated to include patch authors, checkpoint tracing and localisation + features have been removed. + + * Support for (jailbroken) iPhone and iPod Touch has been added. + + Thanks to Florian Forster, Grzegorz Dymarek and especially Michael Tokarev for + their contributions to this version of tinc. + +Version 1.0.9 Dec 26 2008 + + * Fixed tinc as a service under Windows 2003. + + * Fixed reading configuration files that do not end with a newline. + + * Fixed crashes in situations where hostnames could not be resolved or hosts + would disconnect at the same time as session keys were exchanged. + + * Improved default settings of tun and tap devices on BSD platforms. + + * Make IPv6 sockets bind only to IPv6 on Linux. + + * Enable path MTU discovery by default. + + * Fixed a memory leak that occured when connections were closed. + + Thanks to Max Rijevski for his contributions to this version of tinc. + +Version 1.0.8 May 16 2007 + + * Fixed some memory and resource leaks. + + * Made network sockets non-blocking under Windows. + + Thanks to Scott Lamb and "dnk" for their contributions to this version of tinc. + +Version 1.0.7 Jan 5 2007 + + * Fixed a bug that caused slow network speeds on Windows. + + * Fixed a bug that caused tinc unable to write packets to the tun device on + OpenBSD. + +Version 1.0.6 Dec 18 2006 + + * More flexible detection of the LZO libraries when compiling. + + * Fixed a bug where broadcasts in switch and hub modes sometimes would not + work anymore when part of the VPN had become disconnected from the rest. + +version 1.0.5 Nov 14 2006 + + * Lots of small fixes. + + * Broadcast packets no longer grow in size with each hop. This should + fix switch mode (again). + * Generic host-up and host-down scripts. + + * Optionally dump graph in graphviz format to a file or a script. + + * Support LZO 2.0 and later. + + Thanks to Scott Lamb for his contributions to this version of tinc. + +version 1.0.4 May 4 2005 + + * Fix switch and hub modes. + + * Optionally start scripts when a Subnet becomes (un)reachable. + +version 1.0.3 Nov 11 2004 + +* Show error message when failing to write a PID file. + +* Ignore spaces at end of lines in config files. + +* Fix handling of late packets. + +* Unify BSD tun/tap device handling.

Works on Linux, + FreeBSD, possibly OpenBSD but not on Solaris. + +* Support for tunnels over IPv6 networks. Works on all supported + operating systems. + +* Optional compression of UDP connections using zlib. + +* Optionally let UDP connections inherit TOS field of tunneled packets. + +* Optionally start scripts when certain hosts become (un)reachable. + + +version 1.0pre5 Feb 9 2002 + +* Security enhancements: + + * Added sequence number and optional message authentication code to + the packets. + + * Configurable encryption cipher and digest algorithms. + +* More robust handling of dis- and reconnects. + +* Added a "switch" and a "hub" mode to allow bridging setups. + +* Preliminary support for routing of IPv6 packets. + +* Supports Linux, FreeBSD, OpenBSD and Solaris. + + +It looks like this might be the last release before 1.0. + + +version 1.0pre4 Jan 17 2001 + +* Updated documentation; the documentation now reflects the + configuration as it is. + +* Some internal changes to make tinc scale better for large + networks, such as using AVL trees instead of linked lists for the + connection list. + +* RSA keys can be stored in separate files if needed. See the + documentation for more information. + +* tinc has now been reported to run on Linux PowerPC and FreeBSD x86. + + + +version 1.0pre3 Oct 31 2000 + +* The protocol has been redesigned, and although some details are + still under discussion, this is secure. Care has been taken to + resist most, if not all, attacks. + +* Unfortunately this protocol is not compatible with earlier versions, + nor are earlier versions compatible with this version. Because the + older protocol has huge security flaws, we feel that not + implementing backwards compatibility is justified. + +* Some data about the protocol: + + * It uses public/private RSA keys for authentication (this is the + actual fix for the security hole). + + * All cryptographic functions have been taken out of tinc, instead + it uses the OpenSSL library functions. + + * Offers support for multiple subnets per tinc daemon. + +* New is also the support for the universal tun/tap device. This + means better portability to FreeBSD and Solaris. + +* tinc is tested to compile on Solaris, Linux x86, Linux alpha. + +* tinc now uses the OpenSSL library for cryptographic operations. + More information on getting and installing OpenSSL is in the manual. + This also means that the GMP library is no longer required. + +* Further, thanks to Enrique Zanardi, we have Spanish messages; Matias + Carrasco provided us with a Spanish translation of the manual. + + +What still needs to be done before 1.0: + +* Documentation. Especially since the protocol has changed, and a lot + of configuration directives have been added. + + + + version 1.0pre2 May 31 2000 - * Internationalized, Dutch translation available - * Many sanity checks on the meta protocol added + +* This version has been internationalized; and a Dutch translation has + been included. + +* Two configuration variables have been added: + * VpnMask - the IP network mask for the entire VPN, not just our + subnet (as given by MyVirtualIP). The Redhat and Debian packages + use this variable in their system startup scripts, but it is + ignored by tinc. + * Hostnames - if set to `yes', look up the names of IP addresses + trying to connect to us. Default set to `no', to prevent lockups + during lookups. + +* The system startup scripts for Debian and Redhat use + /etc/tinc/nets.boot to find out which networks need to be started + during system boot. + +* Fixes to prevent denial of service attacks by sending random data + after connecting (and even when the connection has been established), + either random garbage or just nonsensical protocol fields. + +* tinc will retry to connect upon startup, does not quit if it doesn't + work the first time. + +* Hosts that are disconnected implicitly if we lose a connection get + deleted from the internal list, to prevent hogging eachother with + add and delete requests when the connection is restored. + + +What still needs to be done before 1.0: + +* Documentation. +* Failover ConnectTo lines, try another one if the first doesn't work. + + + version 1.0pre1 May 12 2000 * New meta-protocol
