LineEnding
field toEncoderConfig
, allowing users to override the Unix-style default. - #425: Preserve time zones when logging times.

Enhancements:

substring-filtering helper to zap’s observer. This is particularly
useful when testing the
SugaredLogger
. - #416: Make
AtomicLevel
implementencoding.TextMarshaler
.

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
tostring
. - #364: To
support buffering outputs, add
Sync
methods tozapcore.Core
,zap.Logger
, andzap.SugaredLogger
. - #371: Rename
the
testutils
package tozaptest
, 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-safeWriteSyncer
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 multipleWriteSyncer
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 theL()
andS()
functions. Users can update their projects withgofmt -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 withgofmt -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 thezapcore
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
andS
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.
