Timberjack v1.1.0

timberjack v1.1.0

Changed

• Rotated filenames now reflect the creation time of the log file, rather than the moment of rotation.
  • This affects both time-based and size-based rotations.
  • The timestamp in the rotated file name corresponds to when the log file was first opened.
  • Improves clarity and accuracy for log analysis, ingestion pipelines, and time-based partitioning.

Compatibility

• No API changes or config changes.
• Backward-compatible.

Timberjack v1.0.0

Timberjack is now production-ready!

This v1.0.0 release marks the first stable version of Timberjack — a fork and enhancement of lumberjack. Timberjack provides a robust, pluggable logging backend with both size-based and time-based rotation features.

Features

• Size-based log rotation (MaxSize)
• Time-based log rotation (RotationInterval)
• Gzip compression of rotated files (Compress)
• Cleanup of old logs (MaxBackups, MaxAge)
• Manual log rotation via Logger.Rotate()
• Preservation of file permissions and ownership (on Linux)
• Fully compatible with io.Writer, including the standard log package
• Comprehensive test suite

This version is API-stable. Future changes to the v1.x series will be backward-compatible. Breaking changes (if any) will be introduced in a future v2.0.0 release.
