Upgrading From 3.21 To 3.22

info

To follow the zero-downtime strategy when upgrading to 3.21, It is recommended to first migrate to latest 3.20.X and turn on the Celery worker to process all data migrations asynchronously. Otherwise, you will need to downtime your solution to ensure correct data migration.

Changes to orders with a zero total amount

The following changes were implemented to orders with a zero total amount:

• No manual charge (Transaction or Payment) object will be created.
• The OrderEvents.ORDER_MARKED_AS_PAID event will no longer be emitted.

Automatic checkout completion behavior change for checkouts with total being 0

Before version 3.22, the following scenario would result in automatic checkout completion. In version 3.22 and onwards, this behavior has changed.

Preconditions:

• Channel has an automatic checkout completion feature enabled
• Checkout has a total amount equal to zero
• Checkout has lines

Upon processing a transaction, the checkout would have been completed because then, it was not considered fully paid. Transaction logic recognized the authorization status change, which triggered automatic checkout completion.

Now, upon processing a transaction, the checkout will not get completed because checkout is already considered fully paid; therefore, transaction logic does not recognize any authorization status change thus automatic checkout completion is not triggered.
