Default cron group configuration has been modified to better accommodate merchants running cron less often than every minute.

The deprecated \Magento\Framework\Option\ArrayInterface is replaced by \Magento\Framework\Data\OptionSourceInterface.

We replaced some deprecated constants in our ImageFinder class.

Catalogs are no longer synced for stores disabled through Stores > All Stores.

Simple products which are part of a bundle now use their own thumbnail, if available, in web insights, not their bundle parent’s thumbnail.

In catalog sync, configurable products now show a price that reflects the lowest available price for the current catalog scope.

Deleting customers who were suppressed in Dotdigital caused an error in the importer; this has been fixed.
