What is a Technical Preview?
With regard to Safe Software's downloadable installers, both FME Desktop and FME Server, the term "Technical Preview" (or "Technology Preview") is applied to new products still under initial development.
Not all documented features may be present, or work as expected. As such, we cannot recommend that products in Technical Preview are used in production environments.
As with all of our software, we are very keen to hear about and assist with any and all issues you may encounter with a Technical Preview, as we would a complete release. Please contact FME Technical Support if you encounter any issues.
