## 2.0.0 - 2019-01-22

- [PR #11](https://github.com/westonganger/paper_trail-association_tracking/issues/11) - Remove null constraint on `version_associations.foreign_type` column which was added in `v1.1.0`. This fixes issues adding the column to existing projects who are upgrading.

- Run `rails g paper_trail_association_tracking:add_foreign_type_to_version_associations` and then migrate your database.
