Notification

Subscribe to release notifications at spelo.ai/changelog (RSS + email). Major releases are also announced on the dashboard as banner notifications.

Backwards compatibility

We maintain backward compatibility on:

  • data-site-id script attribute
  • Public REST API (api.spelo.ai/v1/*) — any breaking change bumps to /v2/
  • Adapter config format in adapter.config.json

Client-widget internal events, data-channel function schemas, and dashboard UI are not part of the stable surface and may change without notice.
