v1.25.0

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

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

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

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
