Detailed Changes

Network

Changed

• The minimum required node version has been updated to 0.4.15.
• Peer candidate selection now includes an additional verification tier that checks popular
  close-range peers via get_version queries before selecting them. This improves peer selection
  quality by confirming peer responsiveness.

API

Added

• MerklePaymentReceipt::add_uploaded method to record chunks that were successfully uploaded,
  enabling more efficient upload resume by skipping re-upload of known chunks.
• uploaded field on MerklePaymentReceipt to persist the set of successfully uploaded chunks
  across upload resume attempts.

Ant Client

Changed

• Merkle payment candidate selection now falls back to KAD-only peer discovery when initial
  Kademlia queries do not return enough candidates, improving upload reliability during network
  churn.
• Merkle upload resume now skips network existence checks for chunks that were successfully uploaded
  in previous batches, in addition to chunks that already existed on the network.
• Merkle uploads now display progress at info level every 10 chunks, providing better visibility
  into upload status.

Fixed

• The --retry-failed flag is now honoured for merkle uploads. Previously, the flag only affected
  regular uploads and merkle uploads would always use the default retry count.

Launchpad

Fixed

• Node status transitions are now reflected in the UI in real-time. The status panel polls more
  frequently during transitional states (starting, stopping) and updates the display as soon as the
  node registry confirms the new state.
• Stale error messages from node start operations are no longer shown when the underlying services
  have already transitioned successfully.
