# TypeScript SDK Changelog

> Release history for @sqds/grid

## 3.1.0

### Minor Changes

* a7bc52d: Add optional feeConfig to createPaymentIntent request

## 3.0.1

### Patch Changes

* 19375ab: bump dependencies
* Refactored main `grid` package - Now uses @grid/crypto instead of inline crypto code, reducing duplication

## 3.0.0

### Major Changes

* adaa877: BREAKING: All public types now use camelCase naming

  Response and request fields have been renamed from snake\_case to camelCase for JavaScript/TypeScript consistency:

  * `otp_sent` → `otpSent`
  * `otp_id` → `otpId`
  * `created_at` → `createdAt`
  * `expires_at` → `expiresAt`
  * `grid_user_id` → `gridUserId`
  * `time_lock` → `timeLock`
  * `admin_address` → `adminAddress`
  * `transaction_signers` → `transactionSigners`
  * `spending_limit_signers` → `spendingLimitSigners`
  * `transaction_signature` → `transactionSignature`
  * `confirmed_at` → `confirmedAt`
  * `GridError.status_code` → `GridError.statusCode`

  Internal API communication still uses snake\_case; transformation happens automatically.
