Launchweek 2 → Day 1 We're excited to announce that Trigger.dev v4 is officially out of beta and is now Generally Available! 🔥 Warm starts 💁♂️ Human-in-the-loop 🔔 HTTP Callbacks 🎛️ Queue priority 🥯 Bun + Node 22 runtimes 🐳 Self-host with Docker or K8s ↓ And so much more…
🔥 Warm starts: The biggest change you'll notice is speed. When a v4 run finishes, the machine stays running for a while. This dramatically cuts start times – most warm starts start in 100-300ms compared to several seconds for cold starts. You can also opt-in to re-use the process when doing a warm start, saving on the time to import your code.
💁♂️ Human-in-the-loop: V4 introduces Waitpoints – a powerful primitive that pauses workflow execution until conditions are met, enabling human-in-the-loop approvals with configurable timeouts.
🔔 HTTP Callbacks for third-party services (which automatically pause billing during waits), and built-in idempotency keys to prevent duplicate operations, with dashboard controls for manual testing and completion.
