This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (sequelize) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Important Notes

2.0.0

There is a parallel "branch" of the project, released as 2.0.0-alphaX in NPM. All those releases are based on the master and will get all the changes of the master. However, 2.0.0 will contain major backwards compatibility breaking changes. Check the changelog of the branch: https://github.com/sequelize/sequelize/blob/milestones/2.0.0/changelog.md

2.0.0 API should be considered unstable

1.6.0

  • We changed the way timestamps are handled. From v1.6.0 on timestamps are stored and loaded as UTC.
  • Support for synchronous migrations has been dropped. up and down methods in migrations do have a third parameter which is the callback parameter. Pass an error or an error message as first parameter to the callback if something went wrong in the migration.
