3.1 Release Notes¶

Notable Changes¶

• Wallet::sign_with_signers: A new method that gives callers fine-grained control over the signing process by accepting a custom list of SignersContainer. The existing Wallet::sign now delegates to it, leaving the existing API unchanged.
• LoadParams::two_path_descriptor: A convenience method on LoadParams for validating that both the external and internal keychains match an expected two-path descriptor when loading a wallet from persistence.
