7## [1.11.0] - 2023-05-02
8### Fixed
9- Fix initialization of `Value` wrappers.
10
11### Added
12- Add `String` method to `atomic.Pointer[T]` type allowing users to safely print
13underlying values of pointers.

15[1.11.0]: https://github.com/uber-go/atomic/compare/v1.10.0...v1.11.0
16
17## [1.10.0] - 2022-08-11
18### Added
19- Add `atomic.Float32` type for atomic operations on `float32`.
20- Add `CompareAndSwap` and `Swap` methods to `atomic.String`, `atomic.Error`,
21 and `atomic.Value`.
22- Add generic `atomic.Pointer[T]` type for atomic operations on pointers of any
23 type. This is present only for Go 1.18 or higher, and is a drop-in for
24 replacement for the standard library's `sync/atomic.Pointer` type.
25
26### Changed
27- Deprecate `CAS` methods on all types in favor of corresponding
28 `CompareAndSwap` methods.

66
67## [1.5.1] - 2019-11-19
68- Fix bug where `Bool.CAS` and `Bool.Toggle` do work correctly together
69 causing `CAS` to fail even though the old value matches.
70
