IAB TCF 2.3 Support (Automatic Upgrade)

We've upgraded how Consentmo generates and validates consent signals to support IAB TCF 2.3, the latest version of the Transparency & Consent Framework used across the EU.

This update happens fully in the background and ensures that consent data sent to ad and analytics partners remains valid, future-proof, and compliant with the newest IAB Europe requirements, without disrupting your shoppers.

What's new for your store:

• More precise vendor disclosure tracking: Consentmo now deterministically records which vendors were actually disclosed to a shopper and reflects that accurately in the consent signal. This ensures your TC strings meet TCF 2.3's stricter validation rules.
• Updated TC string generation (TCF 2.3-ready): All newly generated consent strings now automatically include the required disclosed vendor information, making them valid under TCF 2.3 expectations.
• Smarter handling of existing consent: Previously stored consent strings are handled safely. When a shopper updates or renews their consent, Consentmo applies the new TCF 2.3 logic automatically, with no forced re-consent and no banner resurfacing.
• Stricter post-deadline validation: Consentmo will no longer generate or accept TC strings that don't meet TCF 2.3 rules. This protects your store from sending invalid consent signals after the IAB enforcement deadline.

💡 No design or UI changes were introduced. No action is required from you.
