    Posted on December 31, 2005 by Jon Jensen

    The Interchange Development Group is pleased to announce the release of Interchange 5.4, the latest production-ready version of our web application server. Of the many changes, a few highlights include:

    • Improved pre-fork server model supports even higher traffic.
    • Extensible architecture improvements allow more customization as well as removal of unneeded capabilities.
    • AccumulateCode capability enables more efficient use of memory for production systems.
    • Email enhancements include easy attachment of HTML and files, and development-mode interception of outgoing mail.
    • Cart triggers allow custom subroutines to be executed whenever the cart changes.
    • Better internal XHTML support.
    • New $Row object provides access to the current list row in embedded Perl.
    • DispatchRoutines allows inserting initialization routines without modifying the core.
    • New demo application called “Standard” improves upon the previous “Foundation” demo.
    • More payment gateways supported, including an interface to CPAN’s Business::OnlinePayment.
    • More languages are supported by the admin UI.
    • Of course, many other feature enhancements and bugfixes.

    We recommend that this version be used for new development. Many users of earlier versions of Interchange will want to consider upgrading to Interchange 5.4 after testing it for suitability with their catalogs in a development environment.

    We’d also like to call your attention to the new Interchange website at which also links to the new developer documentation (“xmldocs”).

    Questions should be directed to the Interchange user discussion mailing list:

    We hope you enjoy using Interchange and find it as useful as we do.
