​
Overview

In this release, FormEngine adds the ability to work with form’s JSON using a JSON schema. Now you can validate form’s JSON using the schema in your favorite IDE: Form's JSON 07 Or directly in the designer: Form's JSON 06 The JSON schema also supports your custom components: Form's JSON 05 For more information on the JSON schema, see this part of the documentation. Also in this release, preparatory work has been done to reduce the size of the core package so that your applications are even smaller.

​
Why update

Upgrade to start working with the JSON schema. This release also contains a fix of the Designer’s issue with the Picker property editor (drop-down list).
