 CHANGELOG
 =========
 
+#### **29-Oct-2023**
+
+Fix a reflection parsing regression that was introduced in the last
+update (see: https://github.com/floooh/sokol-tools/issues/109).
+
+This avoids having to deal with 'dummy samplers' when parsing reflection
+information for HLSL, WGSL and MSL by using a common GLSL output
+for parsing reflection data instead of using the HLSL, WGSL and MSL
+output.
+

 > NOTE: this update is required for WebGPU backend update of sokol-gfx!
