What's changed

Breaking changes

• Removed support for the end-of-life v3 trigger dev CLI. Starting a dev session with an old v3 CLI now returns an upgrade message instead of connecting - upgrade to the v4 CLI to continue using trigger dev. (#4198)

Bug fixes

• Fix TS2742 ("inferred type cannot be named") when exporting a chat.agent from a project with declaration emit: ChatTaskWirePayload and ChatInputChunk are now declared in the public @trigger.dev/sdk/chat subpath, so inferred agent types emit portable declarations and the wire types are directly importable. (#4218)

Server changes

These changes affect the self-hosted Docker image and Trigger.dev Cloud:

• Reduce primary database load on the runs page by serving its empty-state check from ClickHouse instead of Postgres. (#4202)
• Fixed submitting your email on the login page reloading back to an empty form instead of showing the magic link confirmation screen. (#4215)
