You can now create and configure Custom Columns for Products directly from the Delta UI. However, all other types of columns are still restricted to Server Administrators and the Support Team.
We have improved the Saved Views widget on the Delta Dashboard (Home Page). Until now, you could see only your Saved Views related to Orders, Catalog, and Purchase Orders. We have added the option to select 3 categories from a list of 11 available ones and pin the one you would like to load on the screen by default. 
We have introduced a new Compact Mode to the Kiosk view of Picklists in Skustack Lens. In this mode, each Picklist Card will be slightly shrunk, only displaying the most relevant information, allowing for more cards to fit on the screen. Additionally, closed picklists will appear in grayscale to easily distinguish them from open ones. You can easily switch back to the default view by clicking on Picklists > Comfortable Mode.
We have added the Shipping Carrier condition to our Order Rule Engine. You can use it to set the rule to apply only to orders created with a specific carrier, or you can use the Is Not In comparison operator and it would skip specific orders.
We have added a new Inventory Client Setting: Show Available Instead Of Physical Quantity In Product Availability Tooltip. This setting controls what information is displayed when you hover over the i icon tooltip in the Items panel of the Order Details page. When enabled, the tooltip will show the item’s current available inventory rather than the physical. Note that any reserves related to the specific order you are viewing will be included in the available inventory shown in the tooltip. 
When adding a General Order Note, you will now be able to tag a specific user, ensuring they receive a Notification within the interface. You can also include your own username, and the note will be added to your notifications list. This feature can be helpful for keeping track of tasks or setting it up as a reminder.
The Shipping Service condition of the Order Rule Engine now allows setting Does not contain as a comparison operator. This means that you can configure the rule to skip processing orders created with the specified service.
We have improved the way we save customer addresses on Shopify Orders. While the addresses longer than 50 characters used to get cut, we will now import them in their entirety.
You can now mark orders as Allow Shipping Without Payment directly while creating the sales order by calling the POST /api/Orders endpoint. By default, you are not able to ship an order unless it is fully charged. With this status set to true, you can ship the order before receiving payment. Ensure all other necessary settings are configured for this workflow.
We have added the ability to import Houzz Orders with Payment Status Authorized. The setting Import Orders as UpPaid has been substituted with a new setting called Import Orders As, which allows you to pick Paid, UnPaid, or Authorized from a dropdown. You can configure this on the Houzz General Company Settings. If you select UnPaid or Authorized, you may need to manually add the payment information later.
