2. v1.0.0-rc.37 Mar 2017pre-release
   Release notes2 sources agree

   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.

7. v1.0.0-rc.223 Feb 2017pre-release
   Release notes2 sources agree

   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.

13. v1.0.0-rc.115 Feb 2017pre-release
    Release notes2 sources agree

    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.

19. v0.1.0-beta.17 Feb 2017pre-release
    Release notes2 sources agree

    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.
