Supported Platforms

Please note that supported platforms are subject to change if a vendor updates its official end-of-life policy. We are unable to continue providing active support for issues specific to an operating system once it goes out of standard support from the vendor. Separately, GT-SUITE does not re-certify previously released versions on newer operating systems, though it is generally a reasonable practice to run older versions of GT-SUITE on newer operating systems.

Please note that we do not re-certify previously released versions of GT-SUITE on newer operating systems. However, it is generally reasonable to run older versions of GT-SUITE on newer operating systems.

Release Schedule for GT-SUITE

GT-SUITE is released yearly, with several update builds released throughout the year. Each major version is named using the calendar year when Build 1 was released. The Release Candidate is intended for early adopters who wish to utilize the new features as soon as possible. Builds released after the Release Candidate are intended for general use.

The planned GT-SUITE release schedule is shown below, but we reserve the right to adjust as needed to serve the GT-SUITE community.

Lifecycle of GT-SUITE

Each year there is a major release of GT-SUITE, which contains new features and usability improvements for both the GUI and physical modeling capabilities. Each version has a planned lifecycle of 4 years after Build 1 is released. The support period for each version will overlap with previous versions such that there will always be four versions with active technical support, thus allowing ample time for all organizations to adopt the latest version before the older version expires.

Each individual version passes through the following phases over its 4-year lifecycle:

Early Adopter Phase – Those who wish to utilize the newest features as soon as possible may install the Release Candidate. The official release of a version is Build 1, which is intended for all users. Full technical support is provided for the Release Candidate until Build 1 is released. After Build 1 is released, early adopters utilizing the Release Candidate should upgrade to Build 1.

Technical Support with Software Updates – During the first year of a new version of GT-SUITE, Gamma Technologies will provide its world-renowned phone and email support to help you utilize GT-SUITE and become more productive and innovative in your field. Additionally, we will work to continually improve the usability and functionality of GT-SUITE by releasing updates to the software, which are referred to as builds. There are two main builds for general use during this period, Build 1.0000 and Build 2.0000. In the event of a specific improvement that is deemed too important to wait for the next build, it will be released and denoted by a fractional build number, such as 1.0001.

Technical Support with Critical Defect Resolution and Security Updates Only – Following GT-SUITE Build 2, we may release patches to Build 2 periodically if there are critical product fixes or security updates that are necessitated. These patches will be labeled as Build 2.01, 2.02, and so on. If no critical product fixes or security updates exist, the patches for Build 2 will not be issued.

Final Build – Build 3 is the final build for the version. Like the minor updates to Build 2, this build will be limited to critical defects and security updates.

Technical Support without Bug Fixes – The second, third, and fourth years of support for a version will continue with our world-renowned phone and email support. We will no longer be developing nor releasing builds of this version, but the most recent build will continue to be available for download.

Unsupported Phase – After four years since Build 1 was released, the version will enter the Unsupported Phase, where we will remove the download/installer from our website. Technical support will be strictly limited to inquiries that are still relevant in supported versions. The timing for this event will be shortly after the release of Build 1 of the latest version of GT-SUITE so that there will typically be four actively supported versions.

We ask that users migrate to a newer version of GT-SUITE before the end of support, so that we may continue to assist you in driving productivity and innovation in your field. Generally, GT-SUITE installations should continue to function past the supported period and can be used for legacy project work.
