# 3.174.0 release notes

1. ✨ **New features**
   1. Added the optional `includeTimestampInSignature` boolean property to Notification webhook subscription responses across all Notification endpoints (`/notifications/v1.0` and `/notifications/v2.0`). On v2.0, this property is also accepted as an optional request field when creating (`POST /notifications/v2.0`) or updating (`PUT /notifications/v2.0/{notification}`) a subscription.
   2. Added the optional `componentInstance` and `connectorId` properties to the Charge Point Configuration key object in responses on `GET /resources/charge-points/v2.0/{chargePoint}/configurations`, `GET /resources/charge-points/v2.0/{chargePoint}/configurations/{key}`, and `PATCH /resources/charge-points/v2.0/{chargePoint}/configurations/{key}`. These fields appear when the configuration key includes OCPP 2.0 component instance or connector ID information.
   3. Added `componentInstance` and `connectorId` as new filter options on the Charge Point Configurations listing endpoint (`GET /resources/charge-points/v2.0/{chargePoint}/configurations`).
   4. Added the optional `subsidy` object to Tariff pricing on all Tariff endpoints (`/resources/tariffs/v1.0`) and the Tariff Snapshot read endpoint (`/resources/tariff-snapshots/v1.0/{tariffSnapshot}`). The object contains `integrationId`, `threshold`, and `compensationRate` fields. This property is available in both request and response payloads.
2. 🔧 **Improvements**
   1. The Charge Point Configuration response now returns the `evseId` property in the key object when available, on `GET /resources/charge-points/v2.0/{chargePoint}/configurations`, `GET /resources/charge-points/v2.0/{chargePoint}/configurations/{key}`, and `PATCH /resources/charge-points/v2.0/{chargePoint}/configurations/{key}`. This field was previously documented in the schema but not included in responses.
3. 🗑️ **Deprecations**
   1. Deprecated the `subsidyIntegrationId` field on Tariff pricing in favor of the new `subsidy` object. Affected endpoints: `GET /resources/tariffs/v1.0`, `POST /resources/tariffs/v1.0`, `GET /resources/tariffs/v1.0/{tariff}`, `PATCH /resources/tariffs/v1.0/{tariff}`, `PUT /resources/tariffs/v1.0/{tariff}`, and `GET /resources/tariff-snapshots/v1.0/{tariffSnapshot}`.
