Changelog

One taxonomy: feeds in, broadcasts out

• The dashboard now has one Feeds section for everything that makes a feed — a single RSS URL, a stack of them, plain web pages, or a topic prompt, with optional LLM filtering — and one Broadcasts section for everything that sends one out: email, Slack/Discord, and webhooks. "Watchers" and "Destinations" as separate concepts are gone.
• Webhook endpoints get a dashboard home under Broadcasts → Webhooks: add endpoints, copy signing secrets, and inspect the per-endpoint delivery log.
• The API is unchanged — smart feeds are still watcher objects at /v1/watchers, and every published guide keeps working as written.

Programmable RSS feeds: ingest, transform, deliver

• Watchers: describe an interest in plain language → auto-discovered sources, LLM relevance filtering with an auditable "why didn't I see X" view, and a durable Atom/JSON feed. One call pipes it into a newsletter.
• Filter your own feeds: bring feed URLs, add a prompt, get one merged, de-duplicated, filtered feed back — with optional per-item LLM summaries.
• Page → feed: sites without a feed are watched by link diffing and served as a clean feed.
• Slack & Discord destinations: push any feed's new items into a channel via an incoming webhook.
• Durable webhooks: deliveries are logged and retried with exponential backoff; inspect them at GET /v1/webhook-endpoints/{id}/deliveries.
• Metered on the same prepaid balance as email: 1 credit per 5 items judged, 1 per summary. Polling, feeds out, chat sinks, and webhooks are free.

Engagement, billing & passwordless login

• Passwordless magic-link login for the dashboard, alongside API keys.
• Open & click tracking with a privacy-respecting per-account toggle.
• Auto-recharge: save a card and top up automatically below a threshold, plus a Stripe billing-portal link.
• Test-send & preview any broadcast before it goes to the list.
• Edit, pause/resume, and test feeds; feeds surface their last poll status.
• Multipart text/plain sent alongside HTML for deliverability.
