Upgrading from v1.4.1 to v1.4.4

This page covers upgrading from Mintlayer v1.4.1 to v1.4.4. There are no consensus forks, no storage version changes, and no resync required.

Orphan pool per-peer quotas​

The orphan pool now enforces a per-peer capacity limit for remote orphans:

  • Peers reached through outbound connections get a larger orphan quota than inbound peers.
  • Eviction honors per-peer reservations, and occupancy is tracked per origin.
  • The new quota fields are exposed through the mempool_get_config RPC method, so update anything that parses its result strictly.

Wallet: quota rejections are transient​

Remote orphan quota rejections are classified as transient errors instead of permanent failures, so wallets retry instead of treating the submission as failed.

Security patches​

Advisory-exposed dependencies were patched (rustls-webpki, webpki-root-certs, tokio) and the cargo-vet imports refreshed.

Changelogs​
