+## [3.3.20] - 2026-04-26
+
+### Fixed
+
+- **FluentMigrator DI:** **`AddFluentMigratorCore`** registers a default **`IVersionTableMetaDataAccessor`**; **`WithVersionTable`** on **`ConfigureRunner`** could still leave **`VersionInfo`** in use. Engine registration now removes any prior **`IVersionTableMetaDataAccessor`** descriptors and registers **`PassThroughVersionTableMetaDataAccessor`** for **`CertsFluentMigratorVersionTableMetaData`** so **`MigrateUp`** always targets **`version_info`**.
+
