v0.3.0

What's Changed

• refactor: split slogging into pretty package
• feat: add service_name to otel trace attributes

Breaking Changes

Package Structure:

• slogging package split into pretty and otel packages
• Import path changes required:

  // Old
  import "github.com/mikluko/slogging"
  
  // New  
  import "github.com/mikluko/slogging/pretty"
  import "github.com/mikluko/slogging/otel"

API Changes:

• New() → pretty.NewHandler()
• WithDestinationWriter() → WithWriter()
• WithOutputEmptyAttrs() → WithOutputEmptyAttrs(true)
• OpenTelemetry tracing moved to separate otel.Wrap() wrapper

New Features

OpenTelemetry Integration:

• Dedicated otel package for tracing integration
• Automatic extraction of service_name from OpenTelemetry resources
• Filters out default unknown_service:* names
• Zero overhead when no tracing context present
• Trace attributes always at root level regardless of log groups

Pretty Handler Improvements:

• Cleaner API with options-based constructor
• Exported Encoder type for external use
• Added WithLevel() option for consistency

Performance

• Otel handler: ~1.4% overhead without tracing, ~70% with active spans
• No memory leaks: All allocations are request-scoped
• Service name extraction: Minimal 4% performance impact

Upgrade Effort: MESO

This release requires moderate effort to upgrade due to package restructuring and API changes.
