Version 0.12.1

This release includes the InternalLogger fix that enables proper logging visibility.

Changes

🐛 Bug Fixes

• Fixed InternalLogger to properly register with logging hierarchy (Fix InternalLogger to properly register with logging hierarchy #127)
  • InternalLogger instances now register with Python's logging manager
  • Handlers properly propagate from parent loggers
  • logging.basicConfig() now works correctly
  • Compatible with both standard logging and structlog
  • Maintains prefab_internal=True extra attribute on log records

🔧 Other Changes

• Fixed CODEOWNERS file formatting (added missing trailing newline)

Impact

Users can now see Prefab's internal logs (config loading, checkpoint updates, SSE connections, etc.) using standard Python logging configuration, without manual workarounds.

Testing

The InternalLogger fix has been tested with:

• ✅ Standard logging (logging.basicConfig)
• ✅ Structlog integration
• ✅ Handler propagation through logger hierarchy
• ✅ prefab_internal extra attribute preservation
