Bitcoin ABC 0.20.11

Bitcoin ABC version 0.20.11 is now available from:

This release includes the following features and fixes:

  • The prioritisetransaction RPC no longer takes a priority_delta argument, which is replaced by a dummy argument for backwards compatibility with clients using positional arguments. The RPC is still used to change the apparent fee-rate of the transaction by using the fee_delta argument.
  • Bare multisig outputs to our keys are no longer automatically treated as incoming payments. As this feature was only available for multisig outputs for which you had all private keys in your wallet, there was generally no use for them compared to single-key schemes. Furthermore, no address format for such outputs is defined, and wallet software can't easily send to it. These outputs will no longer show up in listtransactions, listunspent, or contribute to your balance, unless they are explicitly watched (using importaddress or importmulti with hex script argument). signrawtransaction* also still works for them.
  • The RPC createwallet now has an optional blank argument that can be used to create a blank wallet. Blank wallets do not have any keys or HD seed. They cannot be opened in software older than 0.20.11 Once a blank wallet has a HD seed set (by using sethdseed) or private keys, scripts, addresses, and other watch only things have been imported, the wallet is no longer blank and can be opened in 0.20.x. Encrypting a blank wallet will also set a HD seed for it.
