  • v1.4.1 Changes

    June 08, 2017

    🚀 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 Changes

    May 12, 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 Changes

    April 25, 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 Changes

    April 13, 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 Changes

    March 31, 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 Changes

    March 14, 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 WriteSyncers 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 Changes

    March 07, 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 Changes

    February 21, 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 Changes

    February 14, 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.
    • 0️⃣ 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.

  • v0.3.0 Changes

    October 22, 2024

    0.3.0 - 22 Oct 2024

    💥 Breaking changes:

    • #1339: zapslog: Drop HandlerOptions in favor of HandlerOption,
      which uses the functional options pattern.
    • #1339: zapslog: Rename AddSource option to WithCaller.

    ✨ Enhancements:

    • 🔊 #1339: zapslog: Record stack traces for error logs or higher.
      The new AddStackAt option changes this level.

    🐛 Bug fixes:

    • #1344, #1408: zapslog: Comply fully with slog.Handler contract.
      This includes ignoring empty Attrs, inlining Groups with empty names,
      and omitting groups with no attributes.

    🚀 Thanks to @zekth and @arukiidou for their contributions to this release.
