+## [0.1.2] - 2025-10-09
+
+### Changed
+- **BREAKING**: Refactored `Dates` struct field names from `Start`/`End` to `After`/`Before` for better clarity
+- **BREAKING**: Replaced PostgreSQL-specific `ILIKE` with database-agnostic `LOWER()` function for case-insensitive string matching
+- Changed date exact match from `DATE_TRUNC` to `DATE()` for SQLite compatibility
+- Changed date between query from `BETWEEN` to `>= AND <=` for more explicit inclusive range queries
+- Updated all case-insensitive string patterns to use `LOWER()` with `LIKE` instead of `ILIKE`
+
+### Added
+- Default limit of 10 when using `Offset()` without explicit `Limit()` to prevent unbounded result sets
+- Expanded test database from 5 to 50 diverse users for comprehensive testing
+- Added 9 comprehensive string integration tests covering all match types and case sensitivity
+
+### Fixed
+- Date range queries now work correctly with SQLite and other databases
+- Case-insensitive string matching now works across all databases (SQLite, PostgreSQL, MySQL, etc.)
+- Date query placeholder handling for range queries with two parameters
+
+### Improved
+- Refactored integration tests to use helper functions, reducing code duplication
+- All date integration tests now use consistent patterns with helper functions
+- Sort integration tests updated to verify results with larger dataset
