+## [0.9.1-alpha] - 2026-03-25
+
+> 🔧 Bug fixes and improvements.
+
+### Fixed
+- **CoreMigrateCommand**: Check if audit columns (`created_by`, `updated_by`) are already defined in `columns` config before auto-adding, avoiding duplicate column errors.
+- **CoreMigrateCommand**: Fixed foreign key column detection to respect user-defined columns in config.
+- **CoreMigrateCommand**: Added `bigint` and `bigintunsigned` type mapping support in column creation.
+- **GenericApiController**: Fixed error code validation to properly handle non-integer error codes (defaults to 500).
+- **FrameworkCoreServiceProvider**: Excluded `auth` and `health` from generic route patterns to prevent conflicts.
