# Release Note

We ended our beta versions and released the formal version of TronWeb@6.0.0, which is written with TypeScript. Here are what we do in this update:

1. Fix [issue543](https://github.com/tronprotocol/tronweb/issues/543), replace type AxiosHeaders with `InstanceType<typeof AxiosHeaders>`.
2. Add type for value field in the return of the creation by TransactionBuilder methods.
3. Fix known type errors.
4. Bump axios from 1.6.8 to 1.7.4 and webpack from 5.78.0 to 5.94.0 to address security problems.
5. Add TronWeb.address.toChecksumAddress and TronWeb.address.isChecksumAddress APIs.
6. Fix the wrong action of `deocdeInput` API in Contract module. [#557](https://github.com/tronprotocol/tronweb/issues/557)
