Sequelize is a promise-based Node.js ORM for Postgres, MySQL, SQLite and Microsoft SQL Server. It features solid transaction support, relations, read replication and more.
We have started v5 beta release process. Hopefully this will cover full v5 milestone. You can find upgrade guide and changelog here
