 # trigger.dev
 
+## 4.5.0-rc.5
+
+### Patch Changes
+
+- The MCP server no longer tells the AI agent to wait for a run to complete after every `trigger_task` call. Waiting is now opt-in: the agent only waits when you ask it to (for example "trigger and then wait for it to finish"). This avoids burning tokens polling runs you didn't need to block on and keeps responses clearer. ([#3838](https://github.com/triggerdotdev/trigger.dev/pull/3838))
+- Update the bundled OpenTelemetry packages to their latest releases (`@opentelemetry/sdk-node` 0.218.0, `@opentelemetry/core` 2.7.1, `@opentelemetry/host-metrics` 0.38.3). ([#3810](https://github.com/triggerdotdev/trigger.dev/pull/3810))

 # internal-platform
 
+## 4.5.0-rc.5
+
+### Patch Changes
+
+- Add optional `shouldPauseScaling` to the supervisor consumer pool scaling options to freeze scale-up while it returns true (scale-down stays allowed). ([#3836](https://github.com/triggerdotdev/trigger.dev/pull/3836))
+- Fix `@trigger.dev/core` build: cast the underlying log record exporter when calling `forceFlush` so it typechecks against the updated OpenTelemetry `LogRecordExporter` type (which no longer declares `forceFlush`). ([#3829](https://github.com/triggerdotdev/trigger.dev/pull/3829))
+- `envvars.upload` now accepts an optional `isSecret` flag, letting you create the imported variables as secret (redacted) environment variables. When omitted, variables default to non-secret. ([#3809](https://github.com/triggerdotdev/trigger.dev/pull/3809))
+
+  ```ts
+  await envvars.upload("proj_1234", "prod", {
+    variables: { STRIPE_SECRET_KEY: "sk_live_..." },
+    isSecret: true,
+  });
+  ```
+
+- Offload large trigger payloads to object storage before sending the trigger API request. The SDK uploads packets at or above the existing 128KB limit and sends an `application/store` pointer instead of embedding large JSON in the request body. `TriggerTaskRequestBody` now validates that `application/store` payloads are non-empty storage paths. ([#3785](https://github.com/triggerdotdev/trigger.dev/pull/3785))
+
+  Payload uploads use the same resolved `ApiClient` as the trigger call (including `requestOptions.clientConfig`), not only the global `apiClientManager.client` — so custom `baseURL`, access token, and preview branch apply to both presign and trigger.
+
+- Update the bundled OpenTelemetry packages to their latest releases (`@opentelemetry/sdk-node` 0.218.0, `@opentelemetry/core` 2.7.1, `@opentelemetry/host-metrics` 0.38.3). ([#3810](https://github.com/triggerdotdev/trigger.dev/pull/3810))

 # @trigger.dev/redis-worker
 
+## 4.5.0-rc.5
+
+### Patch Changes
+
+- Make mollifier buffer and drainer internals configurable. `MollifierBuffer` now accepts `ackGraceTtlSeconds`, `maxRetriesPerRequest`, `reconnectStepMs`, and `reconnectMaxMs` options, and `MollifierDrainer` accepts `maxBackoffMs` and `backoffFloorMs`. All default to their previous hardcoded values, so existing behaviour is unchanged. ([#3822](https://github.com/triggerdotdev/trigger.dev/pull/3822))
+- `MollifierDrainer` accepts a `drainBatchSize` option (default 1) that controls how many entries are popped per env per tick — in-flight handlers remain capped by the global `concurrency`. `MollifierBuffer` also gains `getDrainingCount()` / `listStaleDraining()`, backed by a new `mollifier:draining` ZSET maintained atomically with pop/ack/fail/requeue (observability-only).
