# Release Note

## New Features

- **New deserialization support**  
  Added support for deserializing the following transaction types from `raw_data_hex`:

    - `TransferContract`
    - `WithdrawBalanceContract`
    - `WitnessCreateContract`

- **`trx.getCurrentRefBlockParams`**  
  Provides a method to retrieve the parameters required for transaction building. Users can pass these parameters to transaction constructors and customize the header information, making transaction creation more convenient.

- **`trx.signTypedData` alias**  
  Added `trx.signTypedData` as an alias pointing to the legacy `trx._signTypedData` method.

## Changes

- Removed `getHeaderInfo` from the `transactionBuilder` helper library. Use `trx.getCurrentRefBlockParams` instead.

- Moved the `deserializeTransaction` function from `utils/transaction` to `utils/deserializeTx` for better scalability and maintainability of future modules.

- Dependency updates:
    - `axios` upgraded from 1.11.0 to 1.12.2
    - `puppeteer` upgraded from 24.4.0 to 24.23.0

Note:
To improve usability and maintain a cleaner structure, we have moved `utils.crypto._signTypedData` to `utils.typedData.signTypedData` and relocated constants from `utils.address` to `utils.constants`. Here we list the change:
- utils.crypto._signTypedData -> utils.typedData.signTypedData
- utils.address.ADDRESS_SIZE -> utils.constants.ADDRESS_SIZE
- utils.address.ADDRESS_PREFIX -> utils.constants.ADDRESS_PREFIX
- utils.address.ADDRESS_PREFIX_BYTE -> utils.constants.ADDRESS_PREFIX_BYTE
- utils.address.ADDRESS_PREFIX_REGEX -> utils.constants.ADDRESS_PREFIX_REGEX
- utils.address.TRON_BIP39_PATH_PREFIX -> utils.constants.TRON_BIP39_PATH_PREFIX
- utils.address.TRON_BIP39_PATH_INDEX_0 -> utils.constants.TRON_BIP39_PATH_INDEX_0
