July 25th, 2011· This version fixes a performance issue with TCP communication under Windows, and fixes code that, during network outages, could cause tinc to exit when it thought two nodes with identical names were on the same VPN.
May 9th, 2011· Fixed reading configuration files that do not end with a newline. Again.
· Allow arbitrary configuration options being specified on the command line.
· Allow all options in both tinc.conf and the local host config file.
· Configurable replay window, UDP send and receive buffers for performance tuning.
· Try harder to get UDP communication back after falling back to TCP.
· Initial support for attaching tinc to a VDE switch.
· DragonFly BSD support.
· Allow linking with OpenSSL 1.0.0.
April 13th, 2010· Allow building tinc without LZO and/or Zlib.
· Clamp MSS of TCP packets in both directions.
· Experimental StrictSubnets, Forwarding and DirectOnly options, giving more control over information and packets received from/sent to other nodes.
· Ensure tinc never sends symbolic names for ports over the wire.
February 4th, 2010· Really allow fast roaming of hosts to other nodes in a switched VPN.
· Fixes missing or incorrect environment variables when calling host-up/down and subnet-up/down scripts in some cases.
· Allow port to be specified in Address statements.
· Clamp MSS of TCP packets to the discovered path MTU.
· Let two nodes behind NAT learn each others current UDP address and port via a third node, potentially allowing direct communications in a similar way to STUN.
October 19th, 2009· This release fixes potential crashes during shutdown and in rare conditions.
· It improves NAT handling: tinc now copes with mangled port numbers, and will automatically fall back to TCP if direct UDP connection between nodes is not possible.
· Old RSA keys are disabled when generating new ones, and the default size of new RSA keys has been raised to 2048 bits.
· There are many fixes in the path MTU discovery code.
· Tinc can now drop privileges and/or chroot itself.
· The performance on Windows is improved.
December 27th, 2008· This release lets tinc work as a service under Windows 2003, properly handles configuration files that do not end with a newline, fixes crashes in some situations, fixes a memory leak, and has better default settings.
