Looking for maintainers
Due to 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!
Release
v6 release is now available under @latest tag. You can find detailed changelog here.
Note: master branch points to experimental version not suitable for production. All documentation PRs should be opened for v6 branch. All bug-fix / feature PRs should be opened for master branch first, then for their release target branches i.e. v6 or v5.
Installation
$ 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 ServerDocumentation
