Maintenance Release: Gantt 9.1.4, PDF Export Module 0.8.0, Diagram 6.1.2

In a highly competitive market of UI components, reliability is a real differentiator that directly affects user trust and serves as a driver for adoption. That is why regular patch releases remain one of our key priorities, helping us to keep the DHTMLX product line stable, secure, and production-ready. In April, our development team rolled out fixes and improvements for Gantt, PDF export module (for Gantt and Scheduler), and Diagram. Let us take a closer look at what’s inside these patch versions.
