+# [1.6.0]
+### Added
+- Array element; handling multiple points at once (makes transforms faster)
+- Complete overhaul of Optimization:
+  - Optimizer has become SketchOptimizer or MeshOptimizer
+  - MappedSketch is now smoothed by SketchSmoother
+  - Mesh can also be smoothed by MeshSmoother
+- Gear example
+
+### Changed
+- Cell quality: adjusted calculation so that it works for quadrangles and hexahedrons
+- Clamps no longer refer to Vertex objects but only store points as locations
+- Links same as clamps above, locations only
+
+### Removed
+- QuadMap is no longer needed (handled by Grid classes)
+
 # [1.5.3]
 ### Added
 - RoundSolidShape.remove_inner_edges() can now remove edges from a specific face (start, end or both)

+### Sketch Smoothing and Optimization
 
+Points that define a custom sketch can only be placed approximately. Their positions can then be defined by Laplacian smoothing or optimization to obtain best face quality.
