 # Changelog
 
 - Unreleased
+  - Drop our wrapper for NumPy iterators which were deprecated in v0.16.0 as ndarray's iteration facilities are almost always preferable. ([#324](https://github.com/PyO3/rust-numpy/pull/324))
 
 - v0.17.0
   - Add dynamic borrow checking to safely construct references into the interior of NumPy arrays. ([#274](https://github.com/PyO3/rust-numpy/pull/274))
