All releases of Crossroads Load Balancer
Release Notes: This release rolls up many smaller bugfixes, functionality enhancements, and portability issues. Paths can be tweaked during the install process. The Web interface supports basic authentication. 32-bit portability was fixed. Socket handling was rewritten to prevent leakage in high-load situations.
Release Notes: The mutex code has been rewritten to greatly speed up the handling of mutexes. Logging (verbose or debugging) has been rewritten for type safety. A bug involving incorrect processing of HTTP messages was fixed. Several optimizations were added. The startscript xrctl was enhanced.
Release Notes: This version fixes a bug where network sockets would be consumed but not closed. The bug was triggered in some situations where Crossroads could not connect to a previously available back end.
Release Notes: This release has improvements for high-load production environments. The amount of logging was turned down, anti-CPU-hogging measures were introduced, and a potential cause of crashes during peak loads was fixed. The documentation was updated.
Release Notes: This version fixes a number of bugs, features a rewrite of the "stored-ip" dispatcher, introduces counting of back end errors for diagnostic purposes, and features updated documentation.
Release Notes: This version introduces the ability to rewrite Host: headers in HTTP mode with the hostname of a back end to which Crossroads is dispatching. The Activity overview of the Web interface now shows the number of used file descriptors and the maximum limit. A number of bugs were fixed and code parts were slightly reworked.
Release Notes: This version fixes some smaller bugs or omissions, and further improves the management Web interface.
Release Notes: The balancer control script xrctl was rewritten to use an XML configuration file describing all services. The management Web interface is much richer, allowing modification of more properties of the balancer and allowing addition or deletion of back ends. DOS protection was extended to delay or block client IP addresses that exceed a connection threshold. Resolved back end host names are cached to ease the load on DNS. Back end verification supports HTTP GET or TCP connects to ports other than the back end itself. Portability issues for gcc 3.4, Solaris, and 64-bit systems were solved.
Release Notes: This is a stable release. New features include DOS protection capabilities, bugfixes, a "weighted-load" dispatching mode, a richer management Web interface, and a rewritten, optimized HTTP dispatcher which runs 40-50% faster.
Release Notes: This is the next stable version. It introduces much more configurability through the management Web interface. Furthermore, portability issues for older MacOS versions were solved. Crossroads users are encouraged to sign up at the forum at http://xrforum.org.
