# 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.

Thanks to @SteelPhase, @tmshn, @lixingwang, @wyxloading, @moul, @segevfiner, @andy-retailnext and @jcorbin for their contributions to this release.

## 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.

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

Thanks to @YashishDua for their contributions to this release.

This release fixes two bugs.

Bugfixes:

* [#435][]: Support a variety of case conventions when unmarshaling levels.
* [#444][]: Fix a panic in the observer.

## 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)

This release adds a gRPC compatibility wrapper. It is fully backward-compatible.

Enhancements:

* [#402][]: Add a `zapgrpc` package that wraps zap's Logger and implements
  `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"** &mdash; 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.
