+# [1.8.0]
+### Added
+- Hex*/QuadGrid objects now support `merge_tol` for merging approximately coincident points
+
+### Changed
+- Improvement on performance of mesh assembly (5x+)
+- Improvement on performance of optimization (20x+)
+- Minor API change: use `mesh.settings.property` instead of `mesh.settings['property']`
+- Chopping propagation now doesn't overwrite already defined wires within the same block; it's possible to chop two surrounding blocks and the middle one will have different gradings on appropriate wires
+- Bugfixes:
+  - Correct center point of OneCoreDisk
+  - Correct inner angle calculation for optimization
+
+
 # [1.7.1]
 ### Changed
 - Bugfix: wrong grading propagation on inverted wires
