# v2.89.0 - Arezzo Tech TSP Provider & Fuel Validation Update

> arezzo_tech added as a new source_name value across all Telematics API endpoints, and total_cost validation relaxed on fuel transactions

**Released 9th October 2026**

## Arezzo Tech TSP provider support

This release adds `arezzo_tech` as a new valid value for the `source_name` field across all Telematics API endpoints. It also relaxes the validation pattern on the `total_cost` field for fuel transactions. Both changes are additive and backward-compatible.

<Check>
  **Backward-compatible addition:** All changes in this release are purely additive. No existing integrations are affected.
</Check>

### New TSP source name

The following `source_name` value is now valid across all Telematics API endpoints:

| New `source_name` value | Provider |
| - | - |
| `arezzo_tech` | Arezzo Tech |

### Fuel transaction validation relaxed

The `total_cost` field on fuel transaction responses and requests no longer enforces a strict numeric pattern. The field continues to accept the same numeric string values as before — the change removes an overly restrictive regex that could reject valid inputs.

**Affected endpoints:**

| Endpoint | Change |
| - | - |
| `GET /v2/telematics/fuel-transactions` | `total_cost` pattern constraint removed from response schema |
| `POST /v2/telematics/fuel-transactions` | `total_cost` pattern constraint removed from request schema |
