Product Release Life Cycle

4D Product Release Cycle

4D’s product release cycle policy helps you make the right choice when it comes to deciding which version and model to use. For information about the naming and interval of our product releases, see below.

Feature Release: A new release that introduces significant new features in the platform, as well as updated libraries and system APIs, and bug fixes. It's delivered every three months.
Long Term Support Release: Also known as LTS-release. It includes bug fixes and library updates made to a previous release.
4D 18 LTS is 4D’s initial Long Term Support release.

If you need help selecting the release that's right for you, don’t hesitate to contact a sales representative. Please note that the Maintenance program gives you access to both Feature Release and Long Term Support release lines.
