v1.22.0 — Agentic-First Code Generation

Released 2026-02-18. GitHub release.

v1.22.0 replaces the traditional code generator of Microbus with an agentic-first approach that puts your coding agent in the center. It’s now even faster to produce precise code at scale, and all with simple prompts.

Breaking Changes

• AddMetric → IncrementMetric
• connector.Subscribe returns unsub() func
• connector.Unsubscribe removed
• Codegen pkg is removed
• Greedy path args use {...} instead of {+}
• sub.Actor renamed to sub.RequiredClaims
• github.com/microbus-io/fabric/rand deprecated

Your coding agent can upgrade your project for you. Ask the agent to “Follow the workflow at https://raw.githubusercontent.com/microbus-io/fabric/refs/heads/main/setup/bootstrap.md to bootstrap Microbus”.
