The Link to PO filter on the Manage Orders page now has the Was Linked or Never Linked options. When you select this, the grid will display all orders that fulfill either of the two requirements. Was Linked refers to orders that used to have an active link to a PO but no longer do. Never Linked are orders that were never linked to a Purchase Order. 
We have modified the User Name Filter on the Manage Orders page. The filter now supports up to 30 comma-separated values, allowing you to search for several customer emails at a time.
You can now add Is Exported in the Statuses panel of the Purchase Order Details page. It will appear as a checkbox, and by clicking it, you will replicate the Mark Exported/Mark Not Exported action.
You can now use the Update Order Shipping Information REST API endpoint to set an order’s Customer Handling Fee or change its Allow Shiping without Payment status.
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.
