v1.3.9

1.3.9 (2025-10-21)

Features

• Make FileMode for newly created files configurable (#59) (82320e6)

v1.3.8

1.3.8 (2025-10-15)

Fixes & Improvements

• (4c2c743)

• Eliminated multiple data races in concurrent rotations and mill goroutines.
  Internal logic now snapshots configuration and system functions once for each logger instance to ensure safe concurrent use.

• Added deterministic shutdown for background goroutines (mill and scheduled rotation) via WaitGroup synchronization, preventing premature exits or leaks.

• Strengthened Close() to wait safely for goroutine completion without holding locks.

• Improved test suite:

  • Fake clock (fakeCurrentTime) is now lock-protected to avoid race conditions.
  • Tests force UTC for consistent local-time behavior.
  • CI now runs with go test -race to verify concurrency safety.

Internal Changes

• Introduced resolveConfigLocked() for snapshotting logger configuration (time, compression, stat/rename/remove functions) at initialization.
• Simplified mill and rotation goroutine lifecycle management.
• Minor refactoring for clarity and reduced global variable reads.

v1.3.7

1.3.7 (2025-09-19)

Features

• zstd compression support for rotated files (#38) (626a5bd)

• Manual rotate with custom reason (#39) (cf751aa)

Chnaged

• Rename AppendAfterExt to AppendTimeAfterExt (#37) (fea97b9)

Deprecated

• Compress (bool) is deprecated in favor of Compression ("none" | "gzip" | "zstd").
  If Compression is set, it wins; if it’s empty and Compress is true, gzip is used.
  Compress will be removed in v2.

Prevent panic on write after close and improve shutdown robustness (#25) (332b9c2)

Added

• Generic safeClose[T] helper to close channels safely without panic
