This release adds an stop-gap fix to the `Transact` method so that it never transfers value with the `CallTx` is generates. We hard-code `amount = fee` so that no value is transferred regardless of fee sent. This fixes an invalid jump destination error arising from transferring value to non-payable functions with newer versions of solidity. By doing this we can resolve some issues with users of the v0 RPC without making a breaking API change.
