Updating from 3.0

Shoop 4.0 introduces many API changes which could affect projects or
addons based on Shoop 3.0. Here is a list of the API changes and
instructions how to update your code.

• Database changes

  Database migration from 3.0.0 should go smoothly with MySQL and SQLite
  databases. Unfortunately we don't test with PostgreSQL currently and
  found out just before the release that our migrations don't work for
  PostgreSQL. Setting connection.features.can_rollback_ddl to
  False (e.g. in your manage.py) may help in that case.

• Payment and shipping service API is refactored

  • This affects payment and shipping method addons.
  • See :doc:../services document for introduction to the new API.
  • See this pull request <https://github.com/shuup/shuup-checkoutfi/pull/1/files> as an
    example how to refactor the addon code.

• Simple Pricing is renamed to Customer Group Pricing.

  • Prices have to be migrated manually.

• Enum value OrderLineType.CAMPAIGN is renamed to DISCOUNT

  • Replace usages of CAMPAIGN line types with DISCOUNT

• Discount Pricing is removed.

  • Use the new Campaigns features instead.

• order_creator_finished signal is moved from Front to Core

  • Update your imports.
