# Changelog
 | 
						|
 | 
						|
## 1.16.0 (1 Sep 2020)
 | 
						|
 | 
						|
Bugfixes:
 | 
						|
* [#828][]: Fix missing newline in IncreaseLevel error messages.
 | 
						|
* [#835][]: Fix panic in JSON encoder when encoding times or durations
 | 
						|
  without specifying a time or duration encoder.
 | 
						|
* [#843][]: Honor CallerSkip when taking stack traces.
 | 
						|
* [#862][]: Fix the default file permissions to use `0666` and rely on the umask instead.
 | 
						|
* [#854][]: Encode `<nil>` for nil `Stringer` instead of a panic error log.
 | 
						|
 | 
						|
Enhancements:
 | 
						|
* [#629][]: Added `zapcore.TimeEncoderOfLayout` to easily create time encoders
 | 
						|
  for custom layouts.
 | 
						|
* [#697][]: Added support for a configurable delimiter in the console encoder.
 | 
						|
* [#852][]: Optimize console encoder by pooling the underlying JSON encoder.
 | 
						|
* [#844][]: Add ability to include the calling function as part of logs.
 | 
						|
* [#843][]: Add `StackSkip` for including truncated stacks as a field.
 | 
						|
* [#861][]: Add options to customize Fatal behaviour for better testability.
 | 
						|
 | 
						|
Thanks to @SteelPhase, @tmshn, @lixingwang, @wyxloading, @moul, @segevfiner, @andy-retailnext and @jcorbin for their contributions to this release.

						|
 | 
						|
Bugfixes:
 | 
						|
* [#804][]: Fix handling of `Time` values out of `UnixNano` range.

 | 
						|
 | 
						|
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.
 | 
						|
 |

 | 
						|
  be generated for arrays of `time.Time` objects when using string-based time

						|
  formats.
 | 
						|

						|
Bugfixes:
 | 
						|
 | 
						|

 | 
						|
 | 
						|
## v1.4.0 (12 May 2017)
 | 
						|

This release adds a few small features and is fully backward-compatible.
 | 
						|
 | 
						|
Enhancements:
 | 
						|
 | 
						|
* [#424][]: Add a `LineEnding` field to `EncoderConfig`, allowing users to
 | 
						|
  override the Unix-style default.
 | 
						|
* [#425][]: Preserve time zones when logging times.
 | 
						|
* [#431][]: Make `zap.AtomicLevel` implement `fmt.Stringer`, which makes a

						|
  variety of operations a bit simpler.
 | 
						|
 | 
						|
## v1.3.0 (25 Apr 2017)
 | 
						|
 | 
						|
This release adds an enhancement to zap's testing helpers as well as the
 | 
						|
ability to marshal an AtomicLevel. It is fully backward-compatible.
 | 
						|
 | 
						|
Enhancements:
 | 
						|
 | 
						|
* [#415][]: Add a substring-filtering helper to zap's observer. This is
 | 
						|
  particularly useful when testing the `SugaredLogger`.
 | 
						|
* [#416][]: Make `AtomicLevel` implement `encoding.TextMarshaler`.
 | 
						|
 | 
						|
## v1.2.0 (13 Apr 2017)

						|
Enhancements:
 | 
						|
 | 
						|

						|
  `grpclog.Logger`.
 | 
						|
 | 
						|
## v1.1.0 (31 Mar 2017)
 | 
						|
 | 
						|
This release fixes two bugs and adds some enhancements to zap's testing helpers.
 | 
						|
It is fully backward-compatible.
 | 
						|
 | 
						|
Bugfixes:
 | 
						|
 | 
						|
* [#385][]: Fix caller path trimming on Windows.
 | 
						|
* [#396][]: Fix a panic when attempting to use non-existent directories with
 | 
						|
  zap's configuration struct.
 | 
						|
 | 
						|
Enhancements:
 | 
						|
 | 
						|
* [#386][]: Add filtering helpers to zaptest's observing logger.
 | 
						|
 | 
						|
Thanks to @moitias for contributing to this release.
 | 
						|
 | 
						|
## v1.0.0 (14 Mar 2017)
 | 
						|
 | 
						|
This is zap's first stable release. All exported APIs are now final, and no
 | 
						|
further breaking changes will be made in the 1.x release series. Anyone using a
 | 
						|
semver-aware dependency manager should now pin to `^1`.
 | 
						|
 | 
						|
Breaking changes:
 | 
						|
 | 
						|
* [#366][]: Add byte-oriented APIs to encoders to log UTF-8 encoded text without
 | 
						|
  casting from `[]byte` to `string`.
 | 
						|
* [#364][]: To support buffering outputs, add `Sync` methods to `zapcore.Core`,
 | 
						|
  `zap.Logger`, and `zap.SugaredLogger`.
 | 
						|
* [#371][]: Rename the `testutils` package to `zaptest`, which is less likely to
 | 
						|
  clash with other testing helpers.
 | 
						|
 | 
						|
Bugfixes:
 | 
						|
 | 
						|
* [#362][]: Make the ISO8601 time formatters fixed-width, which is friendlier
 | 
						|
  for tab-separated console output.
 | 
						|
* [#369][]: Remove the automatic locks in `zapcore.NewCore`, which allows zap to
 | 
						|
  work with concurrency-safe `WriteSyncer` implementations.
 | 
						|
* [#347][]: Stop reporting errors when trying to `fsync` standard out on Linux
 | 
						|
  systems.
 | 
						|
* [#373][]: Report the correct caller from zap's standard library
 | 
						|
  interoperability wrappers.
 | 
						|
 | 
						|
Enhancements:
 | 
						|
 | 
						|
* [#348][]: Add a registry allowing third-party encodings to work with zap's
 | 
						|
  built-in `Config`.
 | 
						|
* [#327][]: Make the representation of logger callers configurable (like times,
 | 
						|
  levels, and durations).
 | 
						|
* [#376][]: Allow third-party encoders to use their own buffer pools, which
 | 
						|
  removes the last performance advantage that zap's encoders have over plugins.
 | 
						|
* [#346][]: Add `CombineWriteSyncers`, a convenience function to tee multiple
 | 
						|
  `WriteSyncer`s and lock the result.
 | 
						|
* [#365][]: Make zap's stacktraces compatible with mid-stack inlining (coming in
 | 
						|
  Go 1.9).
 | 
						|
* [#372][]: Export zap's observing logger as `zaptest/observer`. This makes it
 | 
						|
  easier for particularly punctilious users to unit test their application's
 | 
						|
  logging.
 | 
						|
 | 
						|
Thanks to @suyash, @htrendev, @flisky, @Ulexus, and @skipor for their
 | 
						|
contributions to this release.
 | 
						|
 | 
						|
## v1.0.0-rc.3 (7 Mar 2017)
 | 
						|
 | 
						|
This is the third release candidate for zap's stable release. There are no
 | 
						|
breaking changes.
 | 
						|
 | 
						|
Bugfixes:
 | 
						|
 | 
						|
* [#339][]: Byte slices passed to `zap.Any` are now correctly treated as binary blobs
 | 
						|
  rather than `[]uint8`.
 | 
						|
 | 
						|
Enhancements:
 | 
						|
 | 
						|
* [#307][]: Users can opt into colored output for log levels.
 | 
						|
* [#353][]: In addition to hijacking the output of the standard library's
 | 
						|
  package-global logging functions, users can now construct a zap-backed
 | 
						|
  `log.Logger` instance.
 | 
						|
* [#311][]: Frames from common runtime functions and some of zap's internal
 | 
						|
  machinery are now omitted from stacktraces.
 | 
						|
 | 
						|
Thanks to @ansel1 and @suyash for their contributions to this release.
 | 
						|
 | 
						|
## v1.0.0-rc.2 (21 Feb 2017)
 | 
						|
 | 
						|
This is the second release candidate for zap's stable release. It includes two
 | 
						|
breaking changes.
 | 
						|
 | 
						|
Breaking changes:
 | 
						|
 | 
						|
* [#316][]: Zap's global loggers are now fully concurrency-safe
 | 
						|
  (previously, users had to ensure that `ReplaceGlobals` was called before the
 | 
						|
  loggers were in use). However, they must now be accessed via the `L()` and
 | 
						|
  `S()` functions. Users can update their projects with
 | 
						|
 | 
						|
  ```
 | 
						|
  gofmt -r "zap.L -> zap.L()" -w .
 | 
						|
  gofmt -r "zap.S -> zap.S()" -w .
 | 
						|
  ```
 | 
						|
* [#309][] and [#317][]: RC1 was mistakenly shipped with invalid
 | 
						|
  JSON and YAML struct tags on all config structs. This release fixes the tags
 | 
						|
  and adds static analysis to prevent similar bugs in the future.
 | 
						|
 | 
						|
Bugfixes:
 | 
						|
 | 
						|
* [#321][]: Redirecting the standard library's `log` output now
 | 
						|
  correctly reports the logger's caller.
 | 
						|
 | 
						|
Enhancements:
 | 
						|
 | 
						|
* [#325][] and [#333][]: Zap now transparently supports non-standard, rich
 | 
						|
  errors like those produced by `github.com/pkg/errors`.
 | 
						|
* [#326][]: Though `New(nil)` continues to return a no-op logger, `NewNop()` is
 | 
						|
  now preferred. Users can update their projects with `gofmt -r 'zap.New(nil) ->
 | 
						|
  zap.NewNop()' -w .`.
 | 
						|
* [#300][]: Incorrectly importing zap as `github.com/uber-go/zap` now returns a
 | 
						|
  more informative error.
 | 
						|
 | 
						|
Thanks to @skipor and @chapsuk for their contributions to this release.
 | 
						|
 | 
						|
## v1.0.0-rc.1 (14 Feb 2017)
 | 
						|
 | 
						|
This is the first release candidate for zap's stable release. There are multiple
 | 
						|
breaking changes and improvements from the pre-release version. Most notably:
 | 
						|
 | 
						|
* **Zap's import path is now "go.uber.org/zap"** — all users will
 | 
						|
  need to update their code.
 | 
						|
* User-facing types and functions remain in the `zap` package. Code relevant
 | 
						|
  largely to extension authors is now in the `zapcore` package.
 | 
						|
* The `zapcore.Core` type makes it easy for third-party packages to use zap's
 | 
						|
  internals but provide a different user-facing API.
 | 
						|
* `Logger` is now a concrete type instead of an interface.
 | 
						|
* A less verbose (though slower) logging API is included by default.
 | 
						|
* Package-global loggers `L` and `S` are included.
 | 
						|
* A human-friendly console encoder is included.
 | 
						|
* A declarative config struct allows common logger configurations to be managed
 | 
						|
  as configuration instead of code.
 | 
						|
* Sampling is more accurate, and doesn't depend on the standard library's shared
 | 
						|
  timer heap.
 | 
						|
 | 
						|
## v0.1.0-beta.1 (6 Feb 2017)
 | 
						|
 | 
						|
This is a minor version, tagged to allow users to pin to the pre-1.0 APIs and
 | 
						|
upgrade at their leisure. Since this is the first tagged release, there are no
 | 
						|
backward compatibility concerns and all functionality is new.
 | 
						|
 | 
						|
Early zap adopters should pin to the 0.1.x minor version until they're ready to
 | 
						|
upgrade to the upcoming stable release.
