Here is what's new in our latest release:

New endpoint: Prepare Transaction From Address

Through this endpoint customers can prepare a transaction from an address with private and public keys. The address doesn’t have to belong to a wallet. The response will include the transaction fee in Wei. The API is part of Blockchain Tools.

Improvement: 

The endpoint Prepare An Account Based Transaction From HD Wallet has been renamed to Prepare A Transaction From an Address in HD Wallet (xPub, yPub, zPub) to more correctly reflect its purpose. 

We’ve also updated our Node.js SDK and our Key Management System on GitHub.

Please update your libraries if you’ve used this endpoint.
