What is new, in plain English

AI rewrite of the broken-links report — every failure now arrives as a plain-language sentence instead of a raw status code.

Stakeholder alerts land in Slack and email with the cause, the blast radius, and the suggested next step already filled in.

Performance budgets are now compared against the last 90 days, so a 4 ms regression does not page on-call at 3 AM.

Added the Agency dashboard: white-label reports, multi-user access, and per-client monitor sharing.

Moved Core Web Vitals sampling to a rolling 28-day window so weekly spikes do not skew the trend line.

Billing portal in-app: upgrade, downgrade, and update payment method without bouncing to Stripe.

Theme toggle is now persistent across browsers when you are signed in, and respects the OS hint otherwise.

Uptime sparklines render server-side so the badge holds together without a flash of empty SVG.

Onboarding checklist now lives on the account page with a dismissible card so it does not crowd the dashboard.

Public status page ships with custom branding and an RSS feed so subscribers do not have to poll.
