Summary

Version 1.17.2 introduces a replace parameter for operation implementations and fixes a SQL Server dialect bug related to default constraint handling.

✨ New Features

  • Added `Operations.implementation_for.replace` parameter to `Operations.implementation_for()`, allowing replacement of existing operation implementations.

🐛 Bug Fixes

  • Fixed issue in SQL Server dialect where the DROP emitted for existing default constraints during an ALTER COLUMN must occur before modifying the column's default and before changing the column's type.
