+# Changelog
+All notable changes to this project will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [1.6.0] - 2020-02-24
+### Changed
+- Drop library dependency on `golang.org/x/{lint, tools}`.
+
+## [1.5.1] - 2019-11-19
+- Fix bug where `Bool.CAS` and `Bool.Toggle` do work correctly together
+  causing `CAS` to fail even though the old value matches.
+
+## [1.5.0] - 2019-10-29
+### Changed
+- With Go modules, only the `go.uber.org/atomic` import path is supported now.
+  If you need to use the old import path, please add a `replace` directive to
+  your `go.mod`.
+
+## [1.4.0] - 2019-05-01
+### Added
+ - Add `atomic.Error` type for atomic operations on `error` values.
+
+## [1.3.2] - 2018-05-02
+### Added
+- Add `atomic.Duration` type for atomic operations on `time.Duration` values.
+
+## [1.3.1] - 2017-11-14
+### Fixed
+- Revert optimization for `atomic.String.Store("")` which caused data races.
+
+## [1.3.0] - 2017-11-13
+### Added
+- Add `atomic.Bool.CAS` for compare-and-swap semantics on bools.
+
+### Changed
+- Optimize `atomic.String.Store("")` by avoiding an allocation.
+
+## [1.2.0] - 2017-04-12
+### Added
+- Shadow `atomic.Value` from `sync/atomic`.
+
+## [1.1.0] - 2017-03-10
+### Added
+- Add atomic `Float64` type.
+
+### Changed
+- Support new `go.uber.org/atomic` import path.
+
+## [1.0.0] - 2016-07-18
+
+- Initial release.

 Simple wrappers for primitive types to enforce atomic access.
 
 ## Installation
-`go get -u go.uber.org/atomic`
+
+```shell
+$ go get -u go.uber.org/atomic@v1
+```
+
+### Legacy Import Path
+
+As of v1.5.0, the import path `go.uber.org/atomic` is the only supported way
+of using this package. If you are using Go modules, this package will fail to
+compile with the legacy import path path `github.com/uber-go/atomic`.
+
+We recommend migrating your code to the new import path but if you're unable
+to do so, or if your dependencies are still using the old import path, you
+will have to add a `replace` directive to your `go.mod` file downgrading the
+legacy import path to an older version.
+
+```
+replace github.com/uber-go/atomic => github.com/uber-go/atomic v1.4.0
+```
+
+You can do so automatically by running the following command.
+
+```shell
+$ go mod edit -replace github.com/uber-go/atomic=github.com/uber-go/atomic@v1.4.0
+```
 
 ## Usage
+
 The standard library's `sync/atomic` is powerful, but it's easy to forget which
 variables must be accessed atomically. `go.uber.org/atomic` preserves all the
 functionality of the standard library, but wraps the primitive types to

 # Changelog
 
+## 1.15.0 (23 Apr 2020)
+
+Bugfixes:
+* [#804][]: Fix handling of `Time` values out of `UnixNano` range.
+* [#812][]: Fix `IncreaseLevel` being reset after a call to `With`.  
+
+Enhancements:
+* [#806][]: Add `WithCaller` option to supersede the `AddCaller` option. This
+  allows disabling annotation of log entries with caller information if
+  previously enabled with `AddCaller`.
+* [#813][]: Deprecate `NewSampler` constructor in favor of 
+  `NewSamplerWithOptions` which supports a `SamplerHook` option. This option
+   adds support for monitoring sampling decisions through a hook.
+
+Thanks to @danielbprice for their contributions to this release.
+
+## 1.14.1 (14 Mar 2020)
+
+Bugfixes:
+* [#791][]: Fix panic on attempting to build a logger with an invalid Config.
+* [#795][]: Vendoring Zap with `go mod vendor` no longer includes Zap's
+  development-time dependencies.
+* [#799][]: Fix issue introduced in 1.14.0 that caused invalid JSON output to
+  be generated for arrays of `time.Time` objects when using string-based time
+  formats.
+
+Thanks to @YashishDua for their contributions to this release.
+
+## 1.14.0 (20 Feb 2020)
+
+Enhancements:
+* [#771][]: Optimize calls for disabled log levels.
+* [#773][]: Add millisecond duration encoder.
+* [#775][]: Add option to increase the level of a logger.
+* [#786][]: Optimize time formatters using `Time.AppendFormat` where possible.
+
+Thanks to @caibirdme for their contributions to this release.
+
+## 1.13.0 (13 Nov 2019)
+
+Enhancements:
+* [#758][]: Add `Intp`, `Stringp`, and other similar `*p` field constructors
+  to log pointers to primitives with support for `nil` values.
+
+Thanks to @jbizzle for their contributions to this release.
+
+## 1.12.0 (29 Oct 2019)
+
+Enhancements:
+* [#751][]: Migrate to Go modules.
+
+## 1.11.0 (21 Oct 2019)
+
+Enhancements:
+* [#725][]: Add `zapcore.OmitKey` to omit keys in an `EncoderConfig`.
+* [#736][]: Add `RFC3339` and `RFC3339Nano` time encoders.
+
+Thanks to @juicemia, @uhthomas for their contributions to this release.
