    context.

Thanks to @​hhk7734, @​jquirke, @​cdvr1993 for their contributions to this release.

v1.25.0

Compare Source

This release contains several improvements including performance, API additions,
and two new experimental packages whose APIs are unstable and may change in the
future.

Enhancements:

  • #​1246: Add zap/exp/zapslog package for integration with slog.
  • #​1273: Add Name to Logger which returns the Logger's name if one is set.
  • #​1281: Add zap/exp/expfield package which contains helper methods
    Str and Strs for constructing String-like zap.Fields.
  • #​1310: Reduce stack size on Any.

Thanks to @​knight42, @​dzakaammar, @​bcspragu, and @​rexywork for their contributions
to this release.

v1.24.0

Compare Source

Enhancements:

  • #​1148: Add Level to both Logger and SugaredLogger that reports the
    current minimum enabled log level.
  • #​1185: SugaredLogger turns errors to zap.Error automatically.

Thanks to @​Abirdcfly, @​craigpastro, @​nnnkkk7, and @​sashamelentyev for their
contributions to this release.

v1.23.0

Compare Source

Enhancements:

  • #​1147: Add a zapcore.LevelOf function to determine the level of a
    LevelEnabler or Core.
  • #​1155: Add zap.Stringers field constructor to log arrays of objects
    that implement String() string.

v1.22.0

Compare Source

Enhancements:

  • #​1071: Add zap.Objects and zap.ObjectValues field constructors to log
    arrays of objects. With these two constructors, you don't need to implement
    zapcore.ArrayMarshaler for use with zap.Array if those objects implement
    zapcore.ObjectMarshaler.
  • #​1079: Add SugaredLogger.WithOptions to build a copy of an existing
    SugaredLogger with the provided options applied.
  • #​1080: Add *ln variants to SugaredLogger for each log level.
    These functions provide a string joining behavior similar to fmt.Println.
  • #​1088: Add zap.WithFatalHook option to control the behavior of the
    logger for Fatal-level log entries. This defaults to exiting the program.
  • #​1108: Add a zap.Must function that you can use with NewProduction or
    NewDevelopment to panic if the system was unable to build the logger.
  • #​1118: Add a Logger.Log method that allows specifying the log level for
    a statement dynamically.

Thanks to @​cardil, @​craigpastro, @​sashamelentyev, @​shota3506, and @​zhupeijun
for their contributions to this release.
