Customer attribute values captured via any input type (dropdown, multiple select, etc.) are now correctly synced as data fields.

We’re now handling an exception thrown if the API user is locked when mapping data fields.

Security is improved for SMTP configuration; SMTP host is now set via a dropdown list of options.

Cart insight data is now sent for all active quotes, even if they have no items. This allows merchants to exit contacts from a program if they empty their cart.

Merchants can now sync website name, store name and store view name via individual data fields.

Wishlist, Review and Order syncs now look up the transactional data sync limit once, prior to looping over websites.

Logging output from the Client class has been improved, and is now consistent across all methods in the API wrapper.

We fixed the exception thrown when trying to fetch stock during catalog sync.

Text compression for saved templates is now restored.

Unit price for some products (simple, with configurable parents) was 0 in cart insight data; this has been fixed.

We improved the way we fetch customer attribute values for data fields; attribute codes containing numbers (for example, title_123) won’t now break the contact sync.

We fixed an issue with inaccurate log output for wishlist sync.

An invalid return type was breaking web API processing for Swagger; this has been fixed.
