**Notes:**

- When using MySQL, TypeORM now connects using `stringifyObjects: true`, in order to avoid a potential security vulnerability
  in the mysql/mysql2 client libraries. You can revert to the old behavior by setting `connectionOptions.extra.stringifyObjects = false`.
- When using SAP HANA, TypeORM now uses the built-in pool from the `@sap/hana-client` library. The deprecated `hdb-pool`
  is no longer necessary and can be removed. See https://typeorm.io/docs/drivers/sap/#data-source-options for the new pool options.
