2) The HTML we provide in the Quantcast Choice Technical Implementation Guide must be hosted by the main domain (the cookie-setting domain) at the URL designated in the config option 'Group Hosted HTML Cookie Access URL'.
Release Notes: [7.11.18]
As of 11 July 2018 , the following updates will be made to the Quantcast Choice code that publishers and current users of Quantcast Choice code should be aware of. This release will impact the Quantcast Choice UX for publishers who have made significant modifications to the UX via CSS overrides.
Note: We will have enabled versioning to allow publishers to pin to a fixed version of the CMP.js file so that they have time to make changes to their customized code to prevent issues with the rollout of this release. If publishers have made significant CSS overrides, they can either correct those prior to the July 11 release to prevent conflicts or can pin to the current release, fix CSS issues and then update to the latest version within 30 days.
CSS Changes
To be compliant with the Quantcast Choice ToS and the IAB Europe Transparency & Consent Framework policies, some elements of the product must not be altered in any way, including through CSS overrides or code injection via custom Javascript. The following elements will be locked down with this release:
- The opaque background that covers the screen behind the modal/banner will be locked so that it cannot be changed in any way. This is to ensure that users are 100% aware that they must interact with the UI prior to being able to interact with content. We have had reports from users that our modal breaks the page and they can’t click on anything, when actually the background has been changed to 0% opacity, rendering it invisible.
- Because Quantcast Choice is a free product, the presentation of the “powered by Quantcast” link is required. We have locked the CSS override of the element and image.
- All navigational elements on the purposes and vendor screens within the scrollable section have been locked as each element is required to be displayed per IAB framework policies.
We have not locked the ability to override any design settings such as colors, fonts or element sizes, including the height and width of modals and banners. These can still be customized through CSS overrides. All previously available design customization options configurable in the self-serve Quantcast Choice tool are still available.
Addition of a persistent button/link to allow users to change consent preferences
When a user sets their consent preferences, the modal / banner will now collapse into a small button in the lower right corner of the screen by default . This is to make sure that users have the ability to change preferences at any time and is required by IAB policy for publishers and CMPs. This feature will be on by default, but can be disabled through the “Display Persistent Consent Link” configuration parameter. In order to disable this option, a publisher must have the link present in a persistent manner elsewhere on the page.
If you experience technical issues with your code, please reach out to support@quantcast.com.
Release Notes: [7.05.18]
- Versioning is now available for Quantcast Choice, see the Technical Implementation Guide for details.
- Integrity hashes are now available to ensure the source code for cmp.js has not been maliciously altered. See the Technical Implementation Guide for details.
- The “powered by Quantcast" link will now open in a new browser tab.
- Addition of missing German translations in the UI.
- Correction of Dutch translations for the on/off toggle labels.
- A fix for the consent window re-appearing multiple times. This was due to subdomains resulting in multiple cookies that caused the modal to reappear.
- Removal of Mixpanel from Quantcast Choice UX. We are moving to a log-based reporting system that does not require user device access or cookie setting. Publisher-accessible reports will be made available in an upcoming release, date TBD.
