Dogecoin Core

Security-related fixes:

This release contains multiple security related fixes:

• The alert system has been removed and processing of alert messages has been disabled
• The transaction download system has been made more reliable
• The protocol implementation has been amended to reject buggy or malformed messages
• Memory management in events of high network traffic or when connected to extremely slow peers has been improved

Fee Recommendation:

• This release changes the recommended dust limit for all participants on the Dogecoin network from 1 DOGE to 0.01 DOGE. The full recommendation can be found in the documentation.

Breaking changes:

• The behavior of the dumpwallet and backupwallet RPC methods, to exclusively write to the directory specified by -backupdir and no longer overwrite files
• The maximum number of addnode records that a node will track has been limited to 800

New features:

• A new RPC method, liststucktransactions has been added to help wallet operators identify if any transactions are stuck (have not been mined and are not in the mempool) and enable resolution. This helps in cases where node-local fee or dust policies change, to prevent the node from sending out old transactions that got lost.
• Pruning configuration has been added to the UI, to make it easier to save diskspace for users of graphical (wallet) installations.
• A new RPC method, setmaxconnections, has been introduced that enables wallet and node operators to change the maximum number of connections their node allows without needing to restart allowing for more fine-grained control of the node's network capacities.
• The graph in the UI's traffic monitor has been significantly improved by keeping track of the traffic we see in the background and then rendering it on demand, at any desired scale.
• A new RPC method, rescan, has been added to allow node operators to rescan the chain for wallet transactions from a certain height. This can help speed up the rescan process for keys that are known to be generated after a certain date or block height.
• A new endpoint has been added to the REST server to find the current best known block at a certain height, without having to do RPC calls. This is useful for service implementations that need to track or query blocks.
