Co Cart Co Cart Versions Save

Bug Fix

• REST API: Class ReserveStock not found when adding products to cart.

Developer note: A line was unintentionally removed that calls the class for use.

In this release, we are happy to provide some of the various improvements made through out the plugin that were from the originally planned v4 release. These improvements are backwards compatible but one change is not. See the developer note for details.

Developer note: This release requires the quantity parameter to pass the value as a string for both adding items or updating items. If you are not new to CoCart then please update your code to account for this change.

Improvements

Developers

These two new headers can help developers use the timestamps of the cart in session for when it is going to expire and how long until it does expire completely.
