jennifer v0.7.0 Release Notes

Release Date: 2019-01-08 // over 5 years ago

  • Overview

    🚀 This release was hard and pretty long. As a result we've got a set of very important features (like polymorphic relations and complex query update mechanism). Also as a side effect bunch of side-shards were appeared to fill gaps in missing functionality (like form parsing).

    🌐 Also you can find 3 sample application describing possible way of integrating web frameworks/libraries with Jennifer:
