- **added** — Allow choosing the region a run executes in when triggering a task through the MCP server
- **changed** — Retry transient connection errors when a run starts for longer so a brief connectivity blip no longer delays its first attempt
- **fixed** — Fix debounce to work when passing an array of items to batchTrigger or batchTriggerAndWait and when triggering from useTaskTrigger

- **changed** — Lower background database load during deployments and dev sessions for projects that use declarative schedules
- **changed** — Triggering a task now does one fewer database write so runs reach the queue slightly faster
- **changed** — Creating or updating a schedule and deploying a project with declarative schedules is faster in long-lived projects with many deploys

##### What's changed

##### Highlights

- Allow task-scoped environment API keys to run batch operations for their permitted tasks. The SDK declares the batch's task set before creation, and `@trigger.dev/core/v3/apiKeys` now exports the additional-key format helper. ([#4389](https://github.com/triggerdotdev/trigger.dev/pull/4389))

##### Improvements
- Refresh package builds for TypeScript 7 compatibility while preserving existing runtime entry points. Projects using `emitDecoratorMetadata()` with TypeScript 7 can install the `@typescript/typescript6` compatibility package alongside it; the package remains optional, so installing the Trigger.dev CLI does not install an additional compiler. ([#4318](https://github.com/triggerdotdev/trigger.dev/pull/4318))
- `AgentChat.reconnect()` now settles promptly when reconnecting to an idle chat instead of holding the connection open for the full long-poll window. Also upgrades the S2 streamstore client to 0.25 and moves realtime streams to S2's current hosts. ([#4349](https://github.com/triggerdotdev/trigger.dev/pull/4349))
- You can now choose the region a run executes in when triggering a task through the MCP server. ([#4439](https://github.com/triggerdotdev/trigger.dev/pull/4439))
- Transient connection errors when a run starts are now retried for longer, so a brief connectivity blip no longer sends the run back through the queue and delays its first attempt. ([#4441](https://github.com/triggerdotdev/trigger.dev/pull/4441))
- `debounce` now works when you pass an array of items to `batchTrigger` or `batchTriggerAndWait`, and when you trigger from `useTaskTrigger`. Previously the option was accepted by the types and dropped before the request was sent, so every trigger created its own run instead of collapsing onto the debounce key. ([#4520](https://github.com/triggerdotdev/trigger.dev/pull/4520))
  
  ```ts
  await myTask.batchTrigger([
  {
    payload: { id: "a" },
    options: { debounce: { key: "same-key", delay: "30s" } },
  },
  {
    payload: { id: "b" },
    options: { debounce: { key: "same-key", delay: "30s" } },
  },
  ]);
  ```
  
  The streaming (async iterable) forms of the batch calls were already forwarding `debounce` correctly.

##### Bug fixes
- Fix a chunk occasionally dropped when a chat.agent run takes over from the warm first turn. The realtime stream writer now reports the inclusive last-written position as the resume cursor, so the agent's first record after the handover is no longer skipped. ([#4349](https://github.com/triggerdotdev/trigger.dev/pull/4349))
- Fix a preloaded `chat.agent` run dropping an in-flight message when it retries after an out-of-memory error. The message being processed when the run hit the OOM is now recovered and re-run on the retry, instead of being skipped while the run waited for a new message. ([#4349](https://github.com/triggerdotdev/trigger.dev/pull/4349))

##### Server changes

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

- Self-hosted deployments can now create multiple full-access API keys for each environment. ([#4390](https://github.com/triggerdotdev/trigger.dev/pull/4390))
- Short links like /_/apikeys now take you straight to that page in your current project and environment, so you no longer need the full URL with your org, project and environment in it. ([#4523](https://github.com/triggerdotdev/trigger.dev/pull/4523))
- The dashboard gets a refreshed Dark theme as its new default look. On the account page you can switch to Light,
