## Summary 5 improvements, 5 bug fixes. ## Improvements - Add experimental Node.js 24 and 26 task runtimes. Set `runtime` to `experimental-node-24` or `experimental-node-26` in `trigger.config.ts`. ([#4085](https://github.com/triggerdotdev/trigger.dev/pull/4085)) - Add `defaultRegion` to the project GET and list API responses; null when unset. ([#4146](https://github.com/triggerdotdev/trigger.dev/pull/4146)) ## Server changes These changes affect the self-hosted Docker image and Trigger.dev Cloud: - Transient internal sync failures are now retried quietly instead of surfacing as errors. ([#4270](https://github.com/triggerdotdev/trigger.dev/pull/4270)) - Optionally route ClickHouse read traffic to a read replica while writes stay on the primary. Set `CLICKHOUSE_READER_URL` to move all reads, or target the busiest paths with `RUNS_LIST_CLICKHOUSE_URL` (runs list) and `EVENTS_READER_CLICKHOUSE_URL` (traces, spans, logs). All optional; unset keeps current behavior. ([#4081](https://github.com/triggerdotdev/trigger.dev/pull/4081)) - Remove the deprecated realtime stream write endpoint used by retired v3 task clients. ([#4250](https://github.com/triggerdotdev/trigger.dev/pull/4250)) - Fix batchTrigger requests that set a per-item idempotency key failing with an error instead of creating and deduplicating the runs ([#4271](https://github.com/triggerdotdev/trigger.dev/pull/4271)) - Speed up idempotency checks on `batchTrigger` calls that use idempotency keys. Large batches against a task with a big run history no longer degrade to multi-second lookups. ([#4255](https://github.com/triggerdotdev/trigger.dev/pull/4255)) - The "Preview branches" usage on the Limits page now counts only preview branches. ([#4283](https://github.com/triggerdotdev/trigger.dev/pull/4283)) - Avoid opening a redundant database connection pool when the legacy and primary databases are the same server, preventing connection usage from doubling. ([#4253](https://github.com/triggerdotdev/trigger.dev/pull/4253)) - Fix pages occasionally loading unstyled or failing to load during a deploy. The dashboard now reloads automatically to recover.
