+## [0.4.0] - 2026-06-03
+
+### Added
+- `add_sink(sink, *, level, **kwargs)` — public API for routing sqlmem log records to any loguru-compatible sink (stream, file, callable); supports all loguru `logger.add()` kwargs including `rotation`, `retention`, etc.
+
+### Changed
+- `pyproject.toml` — bumped version to `0.4.0`
+- `config.py` — replaced destructive `logger.remove()` + forced default sink with `logger.disable("sqlmem")`; sqlmem is now silent by default and does not interfere with the host application's logging setup
+
