+# Changelog
+
+## v0.5.3
+
+### Added
+- **ClickHouse Protocol Support**: New `protocol` field in `ConnectionConfig` for ClickHouse connections (`http`, `https`, `clickhouse`, `clickhouse-secure`)
+
+### Fixed
+- **Fail-safe Validation**: Unknown schema check types and unknown operators now fail instead of silently passing
+- **Float Equality**: Equality/inequality comparisons use epsilon tolerance to avoid floating-point precision issues
+- **Error Wrapping**: All adapter `ExecuteQuery` errors now use `%w` for proper error wrapping
+- **ClickHouse Connector**: `Ping` now actually pings the server before fetching version
+- **Config Loading**: Fixed potential NPE
+- **Regex Compilation**: Check parser regexes compiled once at package level instead of per call
+
+### Changed
+- Upgraded to Go 1.26 and updated all dependencies
+- Moved sample checks file to `examples/checks.yml`
+- Copyright headers updated to 2026
+
+## v0.5.0
+
+### Added
+- **Schema Validation**: New `schema_checks` support for validating database table schemas
+    - `expect_columns` check to validate required column presence and types
+    - `expect_columns_ordered` check to validate required column presence and types in specific order
+    - `columns_not_present` check to ensure specific columns are not present by stop-list or pattern
+- **Enhanced Check Configuration**: New flexible checks format with improved YAML configuration
+- **Database Adapter Architecture**: Refactored to use adapter pattern for better database abstraction
+- **Comprehensive Test Coverage**: Added extensive test suites for all adapters and validation logic
+- **CI/CD Pipeline**: GitHub Actions workflow for automated testing
+
+### Improved
+- **Performance**: Enhanced query execution with optimized adapter interfaces
+- **Configuration**: More flexible check expression parsing and validation
+- **Error Handling**: Better validation and error reporting for check results
+- **Code Quality**: Comprehensive refactoring with improved maintainability
