Enhancements

• Add functionality for constraint checking in the storage to Ecto.Changeset. Support was added for unique_constraint/3 (powered by unique indexes) and foreign_key_constraint/3, assoc_constraint/3 (belongs to) and no_assoc_constraint/3 (has one/many)
• Support empty lists as default values
• Support changing/setting null and default on modify/3 in migrations

Bug fixes

• Do not generate changes when parameters are :empty even for embeds/associations
• Raise on bad options in validate_number/3
• get_field/3 and fetch_field/2 for relations return models
• Ensure NULL and DEFAULT are respected when defining references

Deprecations

• Ecto.Changeset.validate_unique/3 is deprecate in favor of Ecto.Changeset.unique_constraint/3. Read the documentation for the latter for more information on updating

Backwards incompatible changes

• Ecto.Adapters.SQL.query/4 now returns {:ok, result}. Use Ecto.Adapters.SQL.query!/4 for the previous behaviour

Adapter backwards incompatible changes

• Receive context on Ecto.Adapter.insert/update/delete. Expect context on schema load.
