Release 0.71.0

Release 0.71.0 - 24-04-10

Changed

• GA_create_transaction/GA_convert_amount: In addition to id_invalid_amount returned
  when an amount is malformed, the errors id_amount_above_maximum_allowed, id_amount_below_minimum_allowed,
  and id_amount_below_the_dust_threshold are now returned if the amount is a valid number
  but outside of the acceptable range of values for the amount in question.
• GA_get_subaccounts: Now returns additional metadata such as the subaccount
  descriptors, matching the output of GA_get_subaccount.

Fixed

• Multisig: Regularly update the minimum fee rate and prevent fee estimates
  from falling below it. This prevents unexpected submission errors when the
  mempool is full and the minimum required fee increases/decreases.
• Multisig: Changes to subaccount metadata ("name" and "is_hidden")
  are now reflected in logged in sessions when changed by another session.
• Build fixes and security updates

Removed

• GA_rename_subaccount: Has been removed. Please use GA_update_subaccount.
