R-release versions bring you new, 100% tested, stable features every few months, ready for production.

After OVER 30 years of business, 4D has never ceased to innovate. And now we are revolutionizing the 4D product cycle with R-release. This revolution brings you:

  • New features delivered every 3-4 months
  • Stable versions ready for production, with all new features 100% tested
  • A faster, more fine-tuned process more tuned to your feedback
  • dedicated discussion forum for R-release features


Get the absolute latest from the 4D product line. In addition to major releases with numerous new features, and alongside minor releases dedicated to bug fixes, R-release versions incorporate subsets of new features destined for future releases, fully tested and ready for production. Take advantage of it to keep your installation of 4D v17 on the cutting edge of technology, stability, and performance!

The release cycle

Instead of developing and distributing major releases with a large set of features every 18-24 months (as is usually done for large software projects), we have split the feature set into smaller parts, releasing 3-4 new versions each year.


Product cycle

Each set of features are to be published as a new release version, such as 4D v17 R2, 4D v17 R3, and so on. Several releases later, once we have reached the complete feature set for the next major build, the last of the series will be published as the next major version, in this case 4D v18.

Maintenance & Partners

The 4D Maintenance program (as well as licenses included under the 4D Partner program) grants free access to these versions, allowing subscribers to benefit from new features, even between major releases. For customers without Maintenance, 4D will continue to provide minor bug fix releases as in the past. New features can be accessed by purchasing an upgrade as soon the next major release is available.


Immediate and long-term benefits

As we release only a small number of new features at a time, we can focus our efforts – primarily testing – on this reduced set, thus improving stability. Having several versions released over the course of a year also allows us to address customer feature requests on a regular basis. We are working in an iterative way so that we can fine-tune features as we are getting customer feedback about the previous version.
