## What's changed

## Improvements
- Add `node-24` and `node-26` as supported `runtime` options in `trigger.config.ts`. The `experimental-node-24` and `experimental-node-26` names are now deprecated aliases and emit a deprecation warning; switch to `node-24` / `node-26` instead. ([#4337](https://github.com/triggerdotdev/trigger.dev/pull/4337))
  
  ```ts
  import { defineConfig } from "@trigger.dev/sdk";
  
  export default defineConfig({
  runtime: "node-24",
  project: "<your-project-ref>",
  });
  ```
- Avoid logging task run environment variable values at debug level ([#4336](https://github.com/triggerdotdev/trigger.dev/pull/4336))
- Custom chat agent loops get two ergonomic wins for owning the turn loop. ([#4304](https://github.com/triggerdotdev/trigger.dev/pull/4304))
  
  `chat.writeTurnComplete()` now returns the turn boundary's resume cursors (`lastEventId` for the output stream and `sessionInEventId` for the input stream), so you can persist them straight from the task instead of round-tripping them back from the client.
  
  ```ts
  const { lastEventId, sessionInEventId } = await chat.writeTurnComplete();
  await db.chats.update(chatId, { lastEventId, sessionInEventId });
  ```
  
  `chat.pipeAndCapture()` no longer throws when a stream is stopped or fails. It now returns a `PipeAndCaptureResult` whose `message` holds any partial output captured before the stop or failure, alongside a typed `status` (`"complete" | "aborted" | "error"`) and, on failure, the `error`. Read the message off the result:
  
  ```ts
  const { message, status, error } = await chat.pipeAndCapture(result, {
  signal,
  });
  if (message) conversation.addResponse(message);
  if (status === "error") logger.error("turn failed", { error });
  ```
  
  Note: `pipeAndCapture` previously resolved to `UIMessage | undefined`. Update call sites to read `.message` from the returned result.
- Suppress a build-time warning that could appear in Vite-based projects when the optional `@ai-sdk/otel` package is not installed. ([#4188](https://github.com/triggerdotdev/trigger.dev/pull/4188))

## Bug fixes
- Fixes intermittent `trigger dev` run crashes where a run could fail at boot with a cryptic `Cannot find module .../dev-run-worker.mjs` after a rebuild had cleaned up the build directory the run was launched against. Dev runs now retry cleanly instead of hard-crashing when their build directory is missing, the dev watchdog no longer removes the build tree of a still-running session, and a run assigned to a worker version that was superseded by a rebuild now fails fast with a clear message instead of silently hanging until it times out. ([#4276](https://github.com/triggerdotdev/trigger.dev/pull/4276))

## Server changes

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

- Refreshed the side menu: separate organization and account menus, a new project switcher, and the menu is now resizable by dragging its edge. The account Profile page has also been redesigned. ([#4066](https://github.com/triggerdotdev/trigger.dev/pull/4066))
- Allow different organization members to use the same development branch name without sharing or colliding with each other's branch environments. ([#4323](https://github.com/triggerdotdev/trigger.dev/pull/4323))
- Limit account settings email input to 254 characters. ([#4330](https://github.com/triggerdotdev/trigger.dev/pull/4330))
- Prevent duplicate Staging and Preview environments when account setup requests overlap ([#4261](https://github.com/triggerdotdev/trigger.dev/pull/4261))
- Fix the docs link on the empty Prompts page, which pointed to a page that no longer exists. ([#4247](https://github.com/triggerdotdev/trigger.dev/pull/4247))
