And for the GitHub release notes;

Logrus v1.10.0

This release focuses on performance, concurrency correctness, and modern Go alignment.

🚀 Performance

Major improvements in TextFormatter and entry hot paths:

  • ~17% geomean runtime improvement
  • ~26% throughput increase
  • Up to ~40% faster colored formatter output
  • Large allocation reductions across text/colored formatter paths
  • WithError path significantly faster and allocation-free

JSONFormatter performance remains largely unchanged.

🔒 Concurrency & Correctness

  • Fix reentrant logging deadlocks (e.g. logging from within MarshalJSON / formatter code).
  • Eliminate race conditions in entry and formatter paths.
  • Improve locking boundaries around formatter and hooks.

➕ Added

  • Basic slog hook for bridging to Go’s log/slog.

⚠️ Behavioral Changes

  • Minimum Go version is now 1.23.
  • TextFormatter now renders []byte as raw/quoted strings instead of numeric slices.
    If you relied on the previous slice-of-ints output, convert explicitly before logging.

v1.10 is primarily a performance and correctness release with no intentional public API changes.
