Svix Changelog September 2026

Svix has released stable version 2 of its SDKs and CLI across nine programming languages, introducing clearer terminology, removing deprecated operations, changing payload-content defaults, and providing migration guidance. The update also adds an interactive CLI wizard for setting up integrations, an App Portal MCP server that enables customers’ coding agents to inspect and manage webhook issues, and multi-organization membership under one account. Advanced endpoint and Stream sink support has expanded to include major cloud, messaging, and data warehouse services as well as a new Postgres destination, with channel filtering, per-delivery tracking, and configurable endpoint types by environment. Other improvements include the completed rollout of polling endpoints v2 with explicit offset commits, an API for canceling stale pending deliveries, management API access to organization membership data, and bulk payload deletion for selected messages while retaining delivery metadata.
