Bitcoin ABC 0.24.4 Release Notes

Bitcoin ABC version 0.24.4 is now available from:

https://download.bitcoinabc.org/0.24.4/

This release includes the following features and fixes:

• Bitcoin ABC will no longer create an unnamed "" wallet by default when no wallet is specified on the command line or in the configuration files. For backwards compatibility, if an unnamed "" wallet already exists and would have been loaded previously, then it will still be loaded. Users without an unnamed "" wallet and without any other wallets to be loaded on startup will be prompted to either choose a wallet to load, or to create a new wallet.
• A new send RPC with similar syntax to walletcreatefundedpsbt, including support for coin selection and a custom fee rate. Using the new send method is encouraged: sendmany and sendtoaddress may be deprecated in a future release.
• The testmempoolaccept RPC returns size and a fee object with the base fee if the transaction passes validation.
• A “sequence” notifier is added to ZeroMQ notifications, enabling client-side mempool tracking.
• The same ZeroMQ notification (e.g. -zmqpubhashtx=address) can now be specified multiple times to publish the same notification to different ZeroMQ sockets.
• The -startupnotify option can be used to specify a command to execute when Bitcoin ABC has finished with its startup sequence.
