# Release Note

## New Features

- **Added `trx.getContractInfo`**

  Added `trx.getContractInfo(contractAddress)` method that retrieves detailed contract information via the `wallet/getcontractinfo` node API endpoint.

- **Extended `deserializeTx` with full contract type coverage**

  Added deserialization support for all remaining `TransactionBuilder` contract types via `raw_data_hex`:

  - Account: `AccountCreateContract`, `AccountUpdateContract`, `SetAccountIdContract`, `AccountPermissionUpdateContract`
  - Stake / Vote: `FreezeBalanceContract`, `UnfreezeBalanceContract`, `VoteWitnessContract`
  - Proposal: `ProposalCreateContract`, `ProposalApproveContract`, `ProposalDeleteContract`
  - Smart contract: `CreateSmartContract`, `UpdateSettingContract`, `UpdateEnergyLimitContract`, `ClearABIContract`
  - DEX: `ExchangeCreateContract`, `ExchangeInjectContract`, `ExchangeWithdrawContract`, `ExchangeTransactionContract`
  - `UpdateBrokerageContract`


## Improvements

- **Plugin restrictions**  

  - Added `PROTECTED_MODULES` to prevent plugins from overriding 2 modules: `transactionBuilder`, `plugin`.  
  - Added `PROTECTED_METHODS` to block plugins from overriding critical signing/key methods: `sign`, `signMessage`, `signMessageV2`, `signTransaction`, `signTypedData`, `multiSign`, `setPrivateKey`, `ecRecover`.  
  - ⚠️ Note: Plugin support will be removed in the next major version.

- **Bug fix**  

  - Corrected the return type of the `getDelegatedResourceV2` in `trx.ts` to consistently return an array.

## Changes

- Remove dev dependency @eslint/eslintrc.
- Bump serialize-javascript from 7.0.3 to 7.0.5.
