description:
  TypeScript SDK changes in Kora v2.2.0-beta — new constructor, Kit plugin, and
  bundle methods.
---

The `@solana/kora` SDK has been updated with new APIs for the v2.2.0-beta
release. Install the beta SDK:

```bash
pnpm add @solana/kora@beta
```

## Bundle Methods

The SDK now supports all bundle operations:

```typescript
// Estimate bundle fees
const estimate = await client.estimateBundleFee({
  transactions: [base64Tx1, base64Tx2],
  fee_token: "EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v"
});

// Sign a bundle without submitting
const { signed_transactions } = await client.signBundle({
  transactions: [base64Tx1, base64Tx2, base64Tx3],
  signer_key: koraSignerAddress
});

// Sign and submit a bundle to Jito
const { bundle_uuid } = await client.signAndSendBundle({
  transactions: [base64Tx1, base64Tx2, base64Tx3],
  signer_key: koraSignerAddress
});
```

## getVersion

```typescript
const { version } = await client.getVersion();
console.log("Kora server version:", version);
```
