chore: release v4.5.5 (#4267)
## 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.
([#4282](https://github.com/triggerdotdev/trigger.dev/pull/4282))

Server Changes

This directory tracks changes to server-only components (webapp, supervisor, etc.) that are not captured by changesets. Changesets only track published npm packages — server changes would otherwise go undocumented.

When to add a file

Server-only PRs: If your PR only changes apps/webapp/, apps/supervisor/, or other server components (and does NOT change anything in packages/), add a .server-changes/ file.

Mixed PRs (both packages and server): Just add a changeset as usual. No .server-changes/ file needed — the changeset covers it.

Package-only PRs: Just add a changeset as usual.

File format

Create a markdown file with a descriptive name:

.server-changes/fix-batch-queue-stalls.md

With this format:

---
area: webapp
type: fix
---

Speed up batch queue processing by removing stalls and fixing retry race

Fields

  • area (required): webapp | supervisor
  • type (required): feature | fix | improvement | breaking

Description

The body text (below the frontmatter) is a one-line description of the change. Keep it concise — it will appear in release notes.

Writing guidance

These entries are public-facing - they ship verbatim in user-visible release notes. A few rules to keep them clean:

  • Write for the user, not the reviewer. Lead with what the user notices or has to do. If a reader who doesn't know the codebase can't tell what changed for them, rewrite it.
  • One sentence is usually enough. The body is the bullet in the changelog. If you need a paragraph, you're probably describing the implementation rather than the change.
  • Describe behavior, not implementation. Skip internal scopes, middleware names, library specifics, framework internals. Users care about what's different for them, not how it's wired.
  • Never name internal tools or infra. Observability stacks, internal services, infra components, monitoring backends, CI surfaces, AWS specifics - none of these belong in user-facing notes.

Before / after:

  • "The image verification step now parses the manifest's layer media types and returns a new result the finalizer rejects." (describes the wiring; a user can't act on it)
  • "Deploying with an outdated CLI could produce an image that fails to start on every run. These deploys are now stopped before going live, with a message asking you to upgrade the CLI and re-deploy." (what the user sees and does)

Lifecycle

  1. Engineer adds a .server-changes/ file in their PR
  2. Files accumulate on main as PRs merge
  3. The changeset release PR includes these in its summary
  4. After the release merges, CI cleans up the consumed files

Examples

---
area: webapp
type: feature
