The highlight of the update is the introduction of new Shaders Plus Modules. According to the creator, these Modules take all of the add-on's existing features and break them down into modular node groups, which can then be non-destructively inserted into any existing shader setup without replacing the main shader.
"For example, if you already have a complex glass-based setup and would like to add real-time caustics to them, simply add the Caustics Module in front of the shader connection," commented the creator on the new feature.
