Notable changes

Important Updates

Several important updates have been added to Dogecoin Core, including fixes backported from Bitcoin Core's upstream.

Reduce Peer INV Object Counts

Previously, Dogecoin Core nodes would maintain a large list of inventory for each peer. This is excessive and unnecessary and has been reduced to a more reasonable number.

Implemented with #3577

Improve Transaction Request Tracking

A new transaction request tracking system improves the way Dogecoin Core communicates with other peers. Notably, this improvement prioritizes communication with outbound peers over inbound peers and makes CPU and memory use more reliable and scalable with the number of peers.

Implemented with #3577

Improve Orphan Transaction Handling

In previous versions of Dogecoin Core, orphan transactions were processed in a complex fashion. Now they are processed more like regular getdata messages, which allows for more efficient handling of messages arriving from other peers, as well as other code simplifications.

Implemented with #3575

Reduce Getheaders Traffic for INV Messages

Dogecoin Core now sends a getheaders message for one block when announced in an INV message, and it sends only a single such message rather than multiple per INV message. This reduces traffic and simplifies the logic of the code.

Implemented with #3568

Improve Reporting of Difficulty Adjustment Errors

Previously, difficulty adjustment violations were not reported for chains that branched off before the last checkpoint. This has been changed by moving the checkpoint check after the difficulty check.

Implemented with #3576

Security Policy Documented

The SECURITY.md file describes how to report a potential vulnerability or security issue in Dogecoin Core.

Implemented with #3611

Minor Changes
