0.3.26

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.
