In-dashboard AI assistant

Tenant-scoped assistant with tools for broadcasts, schedules, templates, contacts, and WooCommerce automations. Supports image / PDF attachments and reports missing capabilities to the developer registry.

AddedMay 28, 2026

Per-individual scheduled broadcasts

schedule_broadcast and update_schedule now accept audience='phones' for a single recipient. Phones are normalized to +digits so the scheduler matches them at fire time.

ChangedMay 28, 2026

Email templates redesigned

All transactional emails now share a three-card layout (header lockup, body, footer with help + socials + secure strip). No more dependency on an external logo image.

AddedMay 27, 2026

When an order reaches a chosen status, broadcast or schedule an approved template automatically.

AddedMay 27, 2026

Hourly sweep that emails 'renews tomorrow' reminders and revokes paid features on expiry for non-Stripe subscriptions.

ChangedMay 26, 2026

Cool-neutral palette aligned to logo

Dashboard re-skinned to the icon's vivid green + navy + white. Warm beige, orange accent, and purple decoration removed.
