MaterialX v1.39.2 also brings improvements to the classic Worley noise technique, contributed by Chris Rydalch at SideFX and seen here in Karma for Houdini.
Another key contribution is generic color ramps, authored by Jonathan Feldstein at Autodesk and seen below in Arnold for Maya, allowing a new level of flexibility for color controls in MaterialX graphs.

Highlighting one of the key contributions in MaterialX v1.39.2, Masuo Suzuki at NVIDIA contributed the Chiang Hair BSDF, seen below in NVIDIA RTX, which opens the door to the authoring of cross-platform, customizable hair shading models in MaterialX and OpenUSD.
