You can find the detailed changelog here.
Note: Looking for maintainers!
Due to various personal reasons, a bigger part of the former core maintainers (thanks to all your hard work!) have been rather busy recently. Hence, the available time to look after our beloved ORM has been shrinking and shrinking drastically, generating a great chance for you:
We are looking for more core maintainers who are interested in finishing the current TypeScript migration, extending the documentation for v6, organizing issues, reviewing PRs, streamlining the overall code base and planning the future roadmap.
If that sounds interesting to you, please reach out to us on Slack. We are looking forward to meet you!
$ npm i sequelize # This will install v6 # And one of the following: $ npm i pg pg-hstore # Postgres $ npm i mysql2 $ npm i mariadb $ npm i sqlite3 $ npm i tedious # Microsoft SQL Server
