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.
