On January 17th HCL organized a great webinar to tell us all about the new and improved HCL Volt MX Curie. Let’s check what is new with this installment.

What is Volt MX

HCL Volt MX is HCL’s solution to get your applications up and running as fast as possible. Not only will development time drop when using Volt but you will be able to create apps for multiple devices with no extra development needed.

    What’s new in Curie

    As expected, this new installment of Volt MX comes with a sum of great things. Here are the Roadmap Themes HCL had in mind:

    In order to make the installments easier to remember, HCL choose some code names for the next releases:
