Changelog

What shipped, and when — the public/API-relevant subset.

  1. Added POST /v1/calculate — server-side calculator math for all 67 calculators, with an interactive Swagger UI at /v1/docs.

  2. Reworked plan structure across the API and calculators dashboard.

  3. Fixed an nginx bug that let the bare IP address serve duplicate site content.

  4. Shipped the WordPress plugin and expanded the webhook documentation.

  5. Added Google OAuth sign-in; published the WordPress plugin, Privacy, and Terms pages.

  6. Added an admin dashboard: every signed-up user, trial/paid status, and usage.

  7. Switched database schema changes to committed migrations applied in CI, instead of a manual step on the server.

  8. Rebranded from HEAT to ExactCalcs.

  9. Shipped the embeddable widget: config API, per-domain gating, rate limiting, and a dashboard customizer with live preview.
