This release marks a special milestone for me. The very first Substance release happened exactly fifteen years ago, on May 30th 2005. I didn’t quite imagine that I’d be here today, still working on the same codebase.

There’s still a long road ahead to continue exploring the never-ending depths of what it takes to write elegant and high-performing desktop applications in Swing. If you’re in the business of writing just such apps, I’d love for you to take this Radiance release for a spin. Click here to get the instructions on how to add Radiance to your builds. And don’t forget that all of the modules require Java 9 to build and run.

Here’s to the next fifteen years!
