v1.10.1

Logrus v1.10.1

This patch release fixes two issues in field formatting and handling:

• Fix a regression introduced in v1.10.0 where TextFormatter could panic when formatting nil or panicking error and fmt.Stringer values.
• Allow function-backed values implementing error to be used with WithError, WithField, and WithFields.

Dependency Changes

• update github.com/stretchr/testify to v1.12.0

v1.10.0

Logrus v1.10.0

This release focuses on substantial performance improvements, concurrency correctness, and better interoperability with modern Go logging APIs.

🚀 Performance

Major improvements across TextFormatter, entry handling, and common logger paths:

• ~17% lower geomean runtime across the benchmark suite
• ~27% higher geomean formatter throughput
• Common enabled logging paths are ~30–44% faster
• WithError is ~40% faster
• Chained fields are ~46% faster
• TextFormatter paths are up to ~40% faster
• Allocation counts are reduced by ~25–74% across measured TextFormatter cases, with the largest reductions in colored output

The improvements also show up in complete logger paths:

• Logger + TextFormatter is ~31% faster, with ~24% fewer allocations
• Logger + JSONFormatter is ~21% faster, with ~10% fewer allocations

JSONFormatter itself remains largely unchanged in runtime performance, with small allocation reductions.

🔄 log/slog interoperability

v1.10 adds bidirectional interoperability between Logrus and Go's log/slog:

• A Logrus slog hook can forward existing Logrus entries to an slog logger.
• hooks/slog.NewHandler implements slog.Handler, allowing log/slog records to use an existing Logrus logger and its hooks, formatter, and output.
• The handler preserves levels, fields, groups, context, record timestamps, and optionally caller information.
• Caller reporting is configured per handler, without requiring Logrus's logger-wide ReportCaller option.
• Custom slog levels can be mapped to Logrus levels.

1.10.1

Fixes:

• Fix a regression introduced in v1.10.0 where TextFormatter could panic when formatting nil or panicking error and fmt.Stringer values.
• Allow function-backed implementations of error as field values.

1.10.0

Fixes:

• Fix reentrant logging deadlocks in formatter paths.
• Fix race conditions in formatter and entry handling.
• Fix generic Log, Logf, Logln, and LogFn methods unexpectedly panicking when called with PanicLevel. Use the corresponding Panic methods when panic behavior is desired.
• Improve concurrency safety around formatter and hook access.

Features:

• Add slog hook for forwarding Logrus entries to log/slog.
• Add slog.Handler for forwarding log/slog records to a Logrus logger, including levels, fields, groups, context, time, and optional caller reporting. The hook and handler can also be combined to help migrate between Logrus and log/slog.
• Add minimal, composable logging interfaces for each log level. This enables consumers to depend on narrower interfaces, making it easier to substitute or adapt logging implementations.
• Allow Entry.Caller to be set explicitly and preserve it across derived entries, enabling custom caller detection without Logrus overwriting caller information when ReportCaller is enabled.

Changed:

• Raise minimum supported Go version to 1.23.
• TextFormatter now renders []byte values as raw/quoted strings instead of slice-of-ints.
• TextFormatter now uses distinct dimmed colors for debug and trace output.
• TextFormatter now automatically enables colors on Windows terminals with ANSI support, matching the behavior on other platforms.
• Entry.HasCaller is now deprecated in favor of checking Entry.Caller directly.
• Deprecated MutexWrap, which was unintentionally exposed as public API. It remains available as an alias for compatibility but should not be used directly.

Performance:

• Significantly improve TextFormatter performance and reduce allocations.
• Optimize common Entry and Logger hot paths.
• Reduce allocations in caller reporting.
