+17.0.1.3.0 (2026-03-24)
+-----------------------
+
+- Added ``intermediate_colors`` field to ``geoengine.vector.layer``.
+  Accepts comma-separated hex color values (e.g. ``#FF0000,#00FF00``) to
+  define intermediate gradient stops in the colored representation. The
+  gradient is built as: begin → intermediate(s) → end. The field is
+  optional; existing behavior is unchanged when left empty.
