Optimizely.Graph.Commerce 1.5.0

Enhancements

Updated the Optimizely.ContentGraph.Cms dependency to version 4.4.0 and resolved the related breaking changes. This keeps Optimizely.Graph.Commerce aligned with the latest Optimizely Graph CMS package, so Commerce Connect projects can adopt current Graph CMS features and fixes without dependency conflicts. See Optimizely Graph for Commerce Connect for setup details.

Bug fix

COM-21516 – Fixed the NullReferenceException that occurred in the Commerce Graph search provider when the Indexers section was omitted from SearchOptions in appSettings.json.

EPiServer.Commerce 14.45.2

Bug fixes

COM-21191 – Fixed the issue where saving a cart triggered three cache invalidation messages from DefaultOrderRepository, which could flood the Service Bus on high-traffic sites. The number of messages emitted per cart save is now reduced, easing pressure on the Service Bus while keeping cache consistency intact.

COM-21248 – Fixed the issue where the Commerce dashboard displayed incorrect logic and rendering errors when accessed. The dashboard now loads with the expected data and behavior.

COM-21269 – Fixed the incorrect discount calculation that occurred when stacking multiple percentage promotions on the same line item with ApplyPromotionUnitIndividually = true and PromotionExclusionLevel = ExclusionLevel.Unit. The internal ApplyDiscountIndividually method now uses Price instead of PlacedPrice, so combined promotions no longer reduce the line item to a 100% discount.

EPiServer.Commerce 14.45.3

Bug fixes

COM-21395 – Fixed the issue where clicking a catalog row on the catalog root page did not open the catalog item, and where the column-settings sidebar omitted the default columns.

COM-21423 – Fixed the MetaObjectValidationException ("Specified 'Created'/'Modified' field value was out of the range of valid values") that occurred when accessing /episerver/commerce on an empty Commerce project after upgrading CMS to 12.34.2 and Commerce to 14.45.1.

EPiServer.Commerce 14.45.4

Bug fixes

COM-21470 – Fixed the issue where a lower-priority promotion was incorrectly skipped on eligible line items when it shared an exclusion rule with a higher-priority promotion.

COM-21524 – Fixed the HTTP 400 You lack sufficient access rights to perform this operation error that occurred when saving the same variant price entry a second time in the Catalog UI. Successive edits to the same price entry now save without an access-rights error.

COM-21554 – Fixed the validation issue that prevented creating shipping method parameters with different names but the same value.

COM-21642 – Fixed the issue where the RemoveExpiredCarts scheduled job logged "No message" in its history when running under a UI culture without an available translation (for example, Vietnamese).

February

Optimizely.Graph.Commerce 1.4.0

Enhancements

Added data indexes in Graph.Commerce that support the Opal promotions agent.
