@@ -8,6 +8,7 @@ parameter was changed or modulated at runtime.
 * Bugfix: Found a bug in cubic interpolation in the sample player and
 similar bugs in the delay line (and all-pass & comb filters). Refactored
 the cubic interpolation and tested it seperately now.
+* Change: Moved DSP code over to `synfx-dsp` crate.
 * Feature: Matrix::get\_connections() returns information about the connections
 to the adjacent cells.
 * Feature: Added the MatrixCellChain abstraction for easy creation of DSP

 * Feature: Added Scope DSP node and NodeConfigurator/Matrix API for retrieving
 the scope handles for access to it's capture buffers.
 * Feature: Added WBlockDSP visual programming language utilizing the `synfx-dsp-jit` crate.
-* Change: Moved DSP code over to `synfx-dsp` crate.
 * Feature: Added the `FormFM` node that was contributed by Dimas Leenman (aka Skythedragon).
