+## [1.10.0] - 2022-08-11
+### Added
+- Add `atomic.Float32` type for atomic operations on `float32`.
+- Add `CompareAndSwap` and `Swap` methods to `atomic.String`, `atomic.Error`,
+  and `atomic.Value`.
+- Add generic `atomic.Pointer[T]` type for atomic operations on pointers of any
+  type. This is present only for Go 1.18 or higher, and is a drop-in for
+  replacement for the standard library's `sync/atomic.Pointer` type.
+
+### Changed
+- Deprecate `CAS` methods on all types in favor of corresponding
+  `CompareAndSwap` methods.
+
+Thanks to @eNV25 and @icpd for their contributions to this release.
