### Added
13+
- Public API exports in `__init__.py` for all synchronous CRUD functions
14+
- Public API exports in `__init__.py` for all asynchronous CRUD functions with `a_` prefix
15+
- `__version__` attribute set to "0.2.0"
16+

23+
24+
### Fixed
25+
- Fixed type checking errors in `sync.py` and `a_sync.py` modules
26+
- Fixed parameter name inconsistency in `get_row()` function (`lazy_load_keys` was misspelled as `lazy_load_keys` in sync version)
27+
- Fixed return type issues in various CRUD functions
28+
- Fixed relationship loading validation to properly check if attributes are relationships
29+

31+
32+
