2026 Commerce Connect 15 release notes

Follow this article to receive email notifications when new Commerce Connect 15 packages are available for 2026. Product packages are found on the Optimizely NuGet server. 

August

EPiServer.Commerce 15.1.0

Enhancements

• Added aggregation of values from a product's linked variations into its ProductContent in Optimizely Graph, so a single product query returns data aggregated across all of the product's variants. See Index variants in a product document in Optimizely Commerce Connect for information.

Bug fixes

• COM-21603 – Fixed the issue where the pricing and inventory editor did not scroll when adding a new price or inventory. The Save and Cancel buttons are now reachable without zooming out.
• COM-21719 – Fixed the issue where price changes on a catalog entry were not synchronized to Optimizely Graph. New, edited, and deleted prices now appear in Graph immediately.
• COM-21813 – Fixed the issue where the CommerceTrackingAttribute processed tracking after the controller action finished. All recommendations now apply when the action runs.
• COM-21857 – Fixed the issue where order data did not sync to Optimizely Data Platform (ODP). Order search treated a whitespace site ID as a value and returned no orders.
• COM-21891 – Fixed the issue where saving a price on a variant did not work when a matching price already existed. The two prices differed only by the time portion of their applied-on date.

July

EPiServer.Commerce 15.0.2

Bug fixes

• COM-21880 – Fixed an issue where personalization did not apply to content in content areas on categories, variants, bundles, and packages. Publishing a product also no longer removes personalization from the content.

June

EPiServer.Commerce 15.0.1

Bug fixes

• COM-21667 – Fixed an issue where shipping method parameters with different names but the same value were incorrectly rejected as duplicates in the Commerce admin UI.
• COM-21699 – Fixed a database migration failure that occurred when the database collation differed from the server collation.
• COM-21743 – Fixed the Failed to process your payment checkout failure with 3D Secure (3DS) payments.
• COM-21760 – Fixed a performance issue where Commerce UI module builds unnecessarily reprocessed unchanged .zip files in modules\_protected, increasing build times on sites with large module directories.
