New in 2.4

• NEW: dataLayer tab — inspect and validate the page's GA4 events, Consent Mode and GTM containers without the console.
• NEW: GA4 event validation — missing required parameters (e.g. purchase without transaction_id), non-numeric value ("129,00"), value 0, currency that is not an ISO 4217 code, items[] without item_id/item_name, events fired twice, legacy Universal Analytics structure.
• NEW: Consent Mode v2 — reports missing ad_user_data/ad_personalization, update without or before default, and invalid values.
• NEW: PII warning — e-mails, phone numbers, IBANs and card numbers in the dataLayer are detected and reported by path, never by value; they are masked in copies, reports and snapshots.
• NEW: cross-check against the JSON-LD on the same page — price, currency and SKU mismatches between items[] and the Product markup.
• NEW: snapshots — store locally (masked), filter and compare: added, removed, duplicated and changed events, also against the current page.
• Read-only: dataLayer.push is never wrapped, nothing about the page changes. No new permissions.

New in 2.3

• NEW: share preview per network – Facebook, LinkedIn, X, WhatsApp, Slack – each with that platform's truncation limits, image ratio and card layout.
• NEW: complete Open Graph / Twitter tag checklist (essential and recommended). Twitter tags covered by Open Graph are shown as fallback instead of missing.
• NEW: catches the real mistakes – og:url that does not match the canonical, relative or http:// og:image, name="og:…" instead of property= (Facebook ignores it), unknown twitter:card values.
• NEW: image check on the measured file (only after you click "load preview") – below 1200×630, below the 200px minimum, odd aspect ratio, declared og:image:width/height that does not match the file.
• NEW: hreflang validation – BCP-47 syntax (de_AT, en-UK, a country code used as a language), missing self-reference, missing x-default, duplicates and conflicting targets, relative URLs.
• Tools tab: LinkedIn Post Inspector added, the retired X Card Validator link removed.
