Meta Marketing API v24.0 expires October 6

Meta Marketing API v24.0 expires October 6. Any integration, tool, or partner code calling v24 breaks after that date. Why it matters: Audit every API-connected platform (reporting tools, bid managers, custom integrations) against version support lists before Tuesday. Q4 2026 Deadline Calendar / Meta API changelog
GoogleLaw
Google Customer Match now accepts raw IP addresses and interaction timestamps. Both values are uploaded unhashed. IP matching is excluded for EEA, UK, and Switzerland users. Match-rate improvements are activating across all accounts in October 2026. Why it matters: Advertisers without strong PII lists can now build Customer Match audiences from session data - a significant first-party signal expansion ahead of Q4. contentgrip.com / digitalapplied.com

Google DV360 Vertical Video Unification is now live. One 9:16 upload buys across YouTube Shorts and open-web programmatic channels in a single DV360 campaign. Unilever's early test showed 24% more unique reach and 25% lower cost per unique user. Why it matters: Eliminates siloed buying; campaign reach and frequency can now be managed in one platform.

Google
Google faces $3.2 billion in publisher damage claims over ad-tech monopoly. A New York federal judge allowed USA Today, Daily Mail, and a publisher class to seek damages in a jury trial over Google AdX harm. Separately, Google avoided a structural breakup and was ordered to make behavioral changes under oversight instead. Why it matters: Long-term signals continued pressure on Google's ad auction practices; behavioral remedies may shift product decisions that affect advertiser costs. Bloomberg
Google
Google Ads business name policy updated to allow names that differ from the destination domain. Why it matters: More flexibility for agencies running ads under client brand names across multiple properties. Every Google Ads Change in 2026
OpenAI
ChatGPT adds virtual try-on for clothes and accessories, announced October 1. A "Try on" button on product listings lets users upload a selfie for a virtual try-on image. Why it matters: ChatGPT is adding direct shopping utility; another surface where product discovery and conversion can happen outside traditional ad placements. pymnts.com
OpenAITools
Adobe launched a ChatGPT plugin for campaign workflows, launched October 1. It generates visual assets, handles multi-step photo and graphic edits, and organizes cross-channel campaign work. Why it matters: AI-native campaign production is consolidating into fewer tools; worth watching for client workflow implications. martech.org

Data & Privacy Law

Law
France's CNIL email pixel tracking rules are in effect; the transition deadline passed July 14. Any brand emailing recipients in France or Italy now needs two separate consents: one for the marketing email and a distinct one for the open-tracking pixel. Retroactive withdrawal of pixel consent is permitted. Why it matters: Email open rates from French and Italian audiences may be unreliable if pixel consent was not separately collected; non-compliance carries GDPR-scale enforcement risk.

Law
Connecticut now categorically prohibits targeted advertising to anyone under 18, regardless of whether consent is obtained. 20 US states now have comprehensive consumer privacy laws in effect. US State Privacy Law Tracker 2026 / 2026 Privacy Laws and Ad Surveillance

Security alert: a WordPress backdoor is actively rebuilding itself after cleanup. Threat actors are using three persistence mechanisms simultaneously - files, the database, and shared memory - so clearing one layer leaves the infection. Fewer than 20 exploitation attempts observed since July 3, with origins in Bulgaria, Switzerland, France, the US, and Yemen. Why it matters: Standard malware removal will not work; sites need a forensic audit of all three persistence layers. The Hacker News
