Release Notes: This release featured bugfixes and a couple of new features. 64-bit Linux platforms are now supported.
Release Notes: This release provides a fix for a denial of service attack that could crash the program. It also upgraded the versions of the compression libraries used (zlib and bzip2) to take advantage of fixes and improvements in them.
Release Notes: This release included message integrity checking, finer-grained access control, support for for HTTP proxy authentication, much improved server-initiated connection handling, and a good number of bugfixes.
Release Notes: A fix for incorrect selection of client TCP/UDP mode under some circumstances (notably when automatically invoking a command via the "-e" option or "command" keyword).
Release Notes: New features include allowing whole subnet ranges as targets, binding to specific IP addresses, handling both TCP and UDP with a single client/server pair, validating connections based on IP address, tunneling through HTTP proxies, specifying idle connection timeouts, and support for using pre-established shared secret keys.
Release Notes: A number of new features have been added since the last stable release. These include CIDR address specifications for targets, peer IP address checking, connection via a Web proxy supporting the "CONNECT" method, the ability to select the address on which the client or server listens, timeout for inactive TCP mode tunnels, and support for using both UDP and TCP mode tunnels with a single client or server.
Release Notes: Includes missing Japanese documentation. Handles files without a terminating newline. On FreeBSD, only creates a parent process if the program is going to detach. This means there isn't an idle parent process if the program is not run in detached mode. "PUT" handling in ftpgw.tcl fixed. RPM spec file added to the distribution.
Release Notes: A fix for a bug handling literal IP addresses in tunnel and target specifications.
Release Notes: Server-initiated connections to allow a server behind a firewall to connect back to a waiting client, ability for a client and server to handle connections for multiple destinations with the new tunnel and target keywords, support for FreeBSD and Tru64 (on Compaq Alpha), a translation of the manual pages into Japanese, much-improved UDP support, and a whole host of other bugfixes and minor improvements.
Release Notes: The main features introduced in 2.1.0 are server-initiated connections (for use from behind firewalls), support for multiple targets from a single client/server pair and better UDP support (reportedly sufficient to allow you to play Quake through Zebedee tunnels!).
