https://download.bitcoinabc.org/0.22.12/

This release includes the following features and fixes:

• Add an extra 64 bits of entropy in the initial version message.
• The setexcessiveblock RPC is deprecated and will be removed in a future version. The -excessiveblocksize option should be used instead. Use the -deprecatedrpc=setexcessiveblock option to continue using the setexcessiveblock RPC.
• The mempool now tracks whether transactions submitted via the wallet or RPCs have been successfully broadcast. Every 10-15 minutes, the node will try to announce unbroadcast transactions until a peer requests it via a getdata message or the transaction is removed from the mempool for other reasons. The node will not track the broadcast status of transactions submitted to the node using P2P relay. This version reduces the initial broadcast guarantees for wallet transactions submitted via P2P to a node running the wallet.
• getmempoolinfo now returns an additional unbroadcastcount field. The mempool tracks locally submitted transactions until their initial broadcast is acknowledged by a peer. This field returns the count of transactions waiting for acknowledgement.
• Mempool RPCs such as getmempoolentry and getrawmempool with verbose=true now return an additional unbroadcast field. This indicates whether initial broadcast of the transaction has been acknowledged by a peer. getmempoolancestors and getmempooldescendants are also updated.
