What's New is an index, not a publisher: every entry below links to the vendor's own release notes, which are the authoritative source. Entries are labelled where they are hand-curated sample data, pre-releases, or drawn from a secondary source such as a developer blog.

- **added** — The trigger.dev deploy and trigger.dev dev commands now warn with suggested fixes when your code loads a package through createRequire() that won't be available in the deployed image
- **added** — Deploys now show bundler warnings for your code instead of discarding them
- **fixed** — Fix an issue introduced in 4.5.11 that made deploy image builds of projects with large dependency trees noticeably slower
- **changed** — A durable guard improves reliability for runs waiting on triggerAndWait or batchTriggerAndWait if there's a database error that interrupts a child run finishing

##### What's changed

##### Improvements
- The `trigger.dev deploy` and `trigger.dev dev` commands now warn (with the suggested fix) when your code loads a package through `createRequire()` that won't be available in the deployed image. Previously it would fail at runtime in production to load the package. Deploys also now show bundler warnings for your code instead of discarding them. ([#4851](https://github.com/triggerdotdev/trigger.dev/pull/4851))

##### Bug fixes
- Fixes an issue introduced in 4.5.11 that made deploy image builds of projects with large dependency trees noticeably slower. ([#4878](https://github.com/triggerdotdev/trigger.dev/pull/4878))

##### Server changes

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

- A durable guard improves reliability for runs waiting on triggerAndWait or batchTriggerAndWait if there's a database error that interrupts a child run finishing. ([#4849](https://github.com/triggerdotdev/trigger.dev/pull/4849))
