Commerce updates.

Two improvements to Optimizely Commerce functions.

Recording order activities.

Order managers and customer service representatives can now track the history of a specific order for audit and analysis purposes. This new feature automatically records a range of events related to order/shipment status update, payment, and promotion of an order.

(COM-12806) — Product: Episerver Commerce v 13.31.0

Added options for address case in Avalara Tax Connector.

The Avalara CASE option setting for address validations, which were previously hard-coded to uppercase, causing issues with how the address was presented, now defaults to mixed-case and overlooks the CASE option.

(COM-13642) — Product: Episerver Avatax Connector v 2.3.0

Additional Commerce bug fixes and updates.

  • Avalara Tax Connector updated to the latest version (COM-13645)
  • Update to mask the Avalara license key (COM-13918)
  • Update to prevent failure when SEO URL is enabled on product controller (COM-13167)
  • Update to prevent duplicated keys within Cart Properties (COM-12974)
  • LENGTH column of MetaField has been updated (COM-13170)

Marketing automation integration updates.

Additionally, Optimizely has added and updated several features within their Marketing Automation Integration.

Allow user to accept or deny mai_trk_* cookies.

In accordance with GDPR regulations, developers can choose whether to accept cookies for Marketing Automation connectors. Developers are responsible for presenting the cookie option dialog box, obtaining a response, and passing the response to Optimizely. If the user chooses not to accept, some or all functionality of the connector will not work; the form will post successfully but personalization features will not.

(MAI-1886) — Product: Episerver Connect for Marketing Automation Integration v 5.7.0 and all other MAI connectors.

Pardot: update authentication mechanism (leveraging Salesforce OAth).

A newly supported authentication method lets customers leverage Salesforce OAuth flows using Salesforce users, no longer requiring a one-off Pardot only user.

(MAI-1867) — Product: Episerver Marketing Automation Integration for Pardot v 6.0.0

Update of configuration settings due to Microsoft Dynamics CRM connector update.

The Microsoft Dynamics CRM connector updated its authentication to use OAuth, and so the configuration settings screen of was also updated.

(MAI-1892) — Product: Episerver Marketing Automation Integration for MS Dynamics v 5.0.0

Additional bug fixes.

A handful of bug fixes also went through over the past two months. Rather than list them all, feel free to visit the release notes page and filter by date.
