chore: release v4.5.3 (#4219)
## Summary
1 improvement, 2 bug fixes.

## 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](https://github.com/triggerdotdev/trigger.dev/pull/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](https://github.com/triggerdotdev/trigger.dev/pull/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](https://github.com/triggerdotdev/trigger.dev/pull/4202))
- Fixed submitting your email on the login page reloading back to an
empty form instead of showing the magic link confirmation screen.
([#4215](https://github.com/triggerdotdev/trigger.dev/pull/4215))

Official TypeScript SDK for Trigger.dev

The Trigger.dev SDK is a TypeScript/JavaScript library that allows you to define and trigger tasks in your projects.

About Trigger.dev

Trigger.dev is an open source platform for building and deploying fully-managed AI agents and workflows. Write workflows in normal async TypeScript for everything from simple tasks to long-running AI agents, heavy media processing, complex real-time systems and more. Complete with full observability, managed queues, and elastic infrastructure which handles the horizontal scaling.

Core features

  • Task creation and execution
  • CLI for development and deployment
  • Build system with extensions
  • Management API for runs, schedules, and environment variables

Key Components:

  • Tasks: Background jobs written in TypeScript/JavaScript
  • CLI: Commands for login, init, dev, deploy
  • Build Extensions: Customize builds (Prisma, Python, FFmpeg, etc.)
  • Management API: Programmatic control over runs and resources

Getting started

There are two ways to get started:

  1. Create an account in our web app, create a new project and follow the instructions in the onboarding. Build and deploy your first task in minutes.
  2. Manual setup in your existing project.
