IOF Support Extended Through May 31, 2024

The current termination date for Triangle Systems, Inc. support of IOF is April 30, 2024.  Triangle is in preliminary negotiations with a potential successor in interest for the IOF product.  To allow a reasonable amount of time for those negotiations to be concluded, Triangle is extending tech support for IOF until May 31, 2024. Triangle will now provide support for IOF license agreements that extend until May 31, 2024

IOF Support Ending on April 30, 2024

Triangle Systems, Inc. (“Triangle”) has appreciated the loyal support of all Interactive Output Facility (“IOF”) customers, and our people have enjoyed many rewarding relationships with individual customers.  However, Triangle intends to cease operations and legally dissolve on April 30, 2024, and thus, will no longer be able to provide new releases or technical support for IOF Customers after that date.   At the discretion of the IOF Vendor, IOF customers may be offered a fully supported, partial year renewal license that terminates no later than April 30, 2024.

Assuming that IOF has not been acquired by a viable successor in interest, each IOF vendor may choose to offer a free, 1-year extension patch with no IOF support (good through April  30, 2025) to each IOF customer that is licensed and paid up through April 30, 2024 and that has executed Triangle’s liability release agreement.  However, Triangle will provide no further support for, nor accept any responsibility for, usage of IOF past April 30, 2024.   


As an additional measure to help IOF customers who sign the liability release agreement, Triangle will provide free, unsupported utility functions that will allow IOF customers to continue to access data that has been stored in an internal IOF format:
