 ### Changed
 
+- Turned off display in `TruncatedNewton`.
 - Fixed bug in `OptimizationRecorder`. The recorder did not know how to record optimization history without an explictly initialized optimizer.
 - Deprecated `jax_fdm.optimization.optimizers.scipy` in favor of `jax_fdm.optimization.optimizers.gradient_based`.
 - Fixed bug. Return early in `NetworkArtist.edge_width()` if the artist edges list is empty.
