2017 Release Notes release-notes

Feature releases, updates, or changes to the Experience Cloud Identity Service for 2017.

These changes are also captured in the Experience Cloud Release notes.

There are no customer-facing release notes or code changes for March, April, May, and October 2017. For those months, the ID service code remained unchanged at v2.1.

Version 2.5 section-27b441509124493f80984ed09bd9e88b

September, 2017

This is an asynchronous API that returns identifiers for Analytics, the ID service, data collection opt-out, geographic location, and metadata "blob" content by default. Also, you can control which IDs you want to return with the optional visitor.FIELDS enum. See getVisitorValues.

Bug Fixes and Other Changes

  • Fixed a Chrome-related bug that caused the ID service to throw an error when clicking the back button in that browser.
  • The ID service now re-fires ID syncs when the region ID in the event call response changes.
  • Added new documentation, Content Security Policies and the Experience Cloud Identity Service, that explains how to whitelist calls to Adobe domains used by the ID service.

Version 2.3 section-ae7b1cb1e52e4ca5a46b453a3ba1f571

July, 2017

When added to the Visitor.getInstance function, this configuration lets you override the default Supplemental Data ID (SDID) expiration interval when passing that ID from one page to another. You would use sdidParamExpiry with the appendSupplimentalDataTo helper function. See sdidParamExpiry.
This function is designed mainly for A4T customers to help solve issues related to working with IDs on single page sites/screens or apps. See resetState.

Bug Fixes and Other Changes

  • Fixed a bug in VisitorAPI.js v2.2 that prevented the ID service and Target from working together in Internet Explorer.
  • Revised code to help improve how the ID service sends data to the Destination Publishing iFrame. This helps reduce CPU usage.

Version 2.2 section-b7dee2495c29470e9b3a3132ec1fd951

Release date: June, 2017

whitelistParentDomain and whitelistIframeDomains
These configurations let different instances of ID service code implemented in an iFrame and on the parent page communicate with each other. They're designed to help resolve problems with 2 specific use cases where you may or may not control the parent page/domain and you have ID service code loading in the iFrame of a domain that you do control.

Documentation Updates for May section-1d36b91bb7a140ce8a145251ffac9f2f

Updated the Analytics section with information on how to find tracking server information.

Documentation Updates for April section-df3e5a85448c4001a6791517520ae06e

audienceManagerServer and audienceManagerServerSecure
Added links to Audience Manager documentation that describes calls to the demdex.net domain.
Understanding ID Synchronization and Match Rates
Revised Media Optimizer section to describe the call to cm.eversttech.net. This is the automatic ID sync that the ID service performs with Media Optimizer. This feature was released in January, 2017. See Version 2.0 below.

Version 2.1 section-5e666dc47c2f4f92999e92697d75799e

Release date: February, 2017


ID service API property, idSyncContainerID
This property sets the container ID used by Audience Manager for ID syncs. See idSyncContainerID.
ID service API method, appendSupplementalDataIDTo( URL, SDID)
This public method appends the Supplemental Data ID (SDID) as a query string parameter to a redirect URL. See appendSupplementalDataIDTo. (MCID-285)


Fixed a bug that caused the ID service to make redundant server calls for an ID instead of using the ID stored in the AMCV cookie. (MCID-296)

New Documentation

Using DNS Prefetch with Different Experience Cloud Solutions and Services

Version 2.0 section-0ceac6007c1241b58ad607e2b76b2b7e

January, 2017

The ID service code v2.0 automatically synchronizes IDs with Adobe Media Optimizer by default. This means you’ll see a call from the page to cm.eversttech.net, which is a legacy Media Optimizer domain controlled by Adobe. See also, Understanding ID Synchronization and Match Rates.

Fixes and Improvements

  • Fixed a bug that prevented AppMeasurement from making tracking calls to Analytics. (MCID-254, MCID-256, MCID-286)
  • Fixed a bug that prevented the ID service from failing right away if a visitor had enabled an ad blocker and that blocker was configured to exclude the demdex.net domain. This is a rare and unusual bug because most ad blocking tools do not block the demdex.net domain. (MCID-233)
  • Fixed a bug caused by interactions between ID service code and a custom script on a customer’s website. This issue prevented Internet Explorer 9 from loading Web pages. (MCID-206)
