What's new

Key improvements:

Support for Electrum Cash protocol v1.6
Better peering behavior - Fulcrum no longer maintains active connections to all peers, reducing connection overhead
Fixed an esoteric crash bug when using UPnP with more than 1024 connected clients

Version 2.0.0+7 months ago

🚨 This update will automatically trigger a full re-sync of your Fulcrum index. During the re-sync, wallets connected to Fulcrum won't be able to connect.

Fulcrum is now far more resilient to restarts, shutdowns, and power loss, avoiding the database corruption issues that notoriously plagued previous versions.
