Svix Changelog October 2026

Svix announced MCP Events for ChatGPT, enabling agents to subscribe to product events through signed webhooks managed by Svix, alongside a Dashboard MCP that lets coding agents configure and troubleshoot Svix Ingest. Advanced endpoint types have been renamed Advanced Destinations and now offer a public API for programmatic management of polling, storage, queue, database, and related event-delivery destinations, while AutoConfig has expanded to polling endpoints with new token and API management options. The release also adds unified custom domains for customer-facing Svix surfaces, new Free, Basic, and Professional trial plans, IAM role authentication for AWS destinations, Elasticsearch and OpenSearch destinations, and OpenTelemetry-based tracing connectors for Datadog, New Relic, and Grafana Cloud. Additional operational improvements include visible retry schedules, an attempt-statistics API, broader transformation simulation support, expanded PHP SDK capabilities, and organization-leaving and environment-search features.
