 New features
 ------------
 
-- Support for compiling ndarray as `no_std` (using core and alloc) by [@xd009642]
+- Support inserting new axes while slicing by [@jturner314]. This is an example:
 
-  https://github.com/rust-ndarray/ndarray/pull/861
+  ```rust
+  let view = arr.slice(s![.., -1, 2..;-1, NewAxis]);
+  ```
+
+  https://github.com/rust-ndarray/ndarray/pull/570
+
+- Support two-sided broadcasting in arithmetic operations with arrays by [@SparrowLii]
+
+  Note that this means that a new trait bound is required in some places when
+  mixing dimensionality types of arrays in arithmetic operations.

+  https://github.com/rust-ndarray/ndarray/pull/889
 
 - New methods `.cell_view()` and `ArrayViewMut::into_cell_view` that enable
   new ways of working with array elements as if they were in Cells - setting
-  elements through shared views and broadcast views.
+  elements through shared views and broadcast views, by [@bluss].
 
   https://github.com/rust-ndarray/ndarray/pull/877
 
+- New methods `slice_each_axis/_mut/_inplace` that make it easier to slice
+  a dynamic number of axes in some situations, by [@jturner314]
+
+  https://github.com/rust-ndarray/ndarray/pull/913
+
+- New method `a.assign_to(b)` with the inverse argument order compared to the
+  existing `b.assign(a)` and some extra features like assigning into
+  uninitialized arrays, By [@bluss].
+
+  https://github.com/rust-ndarray/ndarray/pull/947
 
 Enhancements
 ------------
 
-- Fix `Zip` for the 0-dimensional case by [@jturner314]
+- New constructors `Array::from_iter` and `Array::from_vec` by [@bluss].
+  No new functionality, just that these constructors are avaiable without trait
+  imports.
 
-  https://github.com/rust-ndarray/ndarray/pull/862
+  https://github.com/rust-ndarray/ndarray/pull/921
+
+- Ndarray can now correctly determine that arrays can be contiguous, even if
+  they have negative strides, by [@SparrowLii]
+
+  https://github.com/rust-ndarray/ndarray/pull/885
+
+- `NdProducer::raw_dim` is now a documented method by [@jturner314]
+
+  https://github.com/rust-ndarray/ndarray/pull/918
+
+- `AxisDescription` is now a struct with field names, not a tuple struct by
+  [@jturner314]
+
+  https://github.com/rust-ndarray/ndarray/pull/915
+
+- Improvements to `map_inplace` by [@jturner314]
+
+  https://github.com/rust-ndarray/ndarray/pull/911
+
+- `.into_dimensionality` performance was improved for the `IxDyn` to `IxDyn`
+  case by [@bluss]
+
+  https://github.com/rust-ndarray/ndarray/pull/906
+
+- Improved performance for scalar + &array and &array + scalar operations by
+  [@jturner314]
+
+  https://github.com/rust-ndarray/ndarray/pull/890
+
+- Methods for array comparison `abs_diff_eq` and `relative_eq` are now
+  exposed as inherent methods too (no trait import needed), still under the approx
+  feature flag by [@bluss]
+
+  https://github.com/rust-ndarray/ndarray/pull/946
 
 API changes
 -----------
 
-- Removed deprecated methods by [@bluss]:
+- Changes to the slicing-related types and macro by [@jturner314] and [@bluss]:
+
+  - Remove the `Dimension::SliceArg` associated type, and add a new `SliceArg`
+    trait for this purpose.
+  - Change the return type of the `s![]` macro to an owned `SliceInfo` rather
+    than a reference.
+  - Replace the `SliceOrIndex` enum with `SliceInfoElem`, which has an
+    additional `NewAxis` variant and does not have a `step_by` method.
+  - Change the type parameters of `SliceInfo` in order to support the `NewAxis`
+    functionality and remove some tricky `unsafe` code.
+  - Mark the `SliceInfo::new` method as `unsafe`. The new implementations of
+    `TryFrom` can be used as a safe alternative.
+  - Remove the `AsRef<SliceInfo<[SliceOrIndex], D>> for SliceInfo<T, D>`
+    implementation. Add the similar `From<&'a SliceInfo<T, Din, Dout>> for
+    SliceInfo<&'a [SliceInfoElem], Din, Dout>` conversion as an alternative.
+  - Change the *expr* `;` *step* case in the `s![]` macro to error at compile
+    time if an unsupported type for *expr* is used, instead of panicking at
+    runtime.
