Bitcoin ABC 0.24.1 Release Notes

Bitcoin ABC version 0.24.1 is now available from:

https://download.bitcoinabc.org/0.24.1/

This release includes the following features and fixes:

CLI

A new bitcoin-cli -generate command, equivalent to RPC generatenewaddress followed by generatetoaddress, can generate blocks for command line testing purposes. This is a client-side version of the former generate RPC. See the help for details.

Low-level RPC Changes

• To make RPC sendtoaddress more consistent with sendmany the following error sendtoaddress codes were changed from -4 to -6:
  • Insufficient funds
  • Transaction has too long of a mempool chain
• Exposed transaction version numbers are now treated as unsigned 32-bit integers instead of signed 32-bit integers. This matches their treatment in consensus logic. Versions greater than 2 continue to be non-standard (matching previous behavior of smaller than 1 or greater than 2 being non-standard). Note that this includes the joinpsbt command, which combines partially-signed transactions by selecting the highest version number.

Notification changes

-walletnotify notifications are now sent for wallet transactions that are removed from the mempool because they conflict with a new block. These notifications were sent previously before the v0.21.13 release, but had been broken since that release.
