This release includes the following features and fixes:

• Add the finalized block concept. Finalized blocks cannot be reorged, which protects the network against deep reorgs.
• Add the -maxreorgdepth configuration to configure at what depth block are considered final. Default is 10. Use -1 to disable.
• Introduce finalizeblock RPC to finalize a block at the will of the node operator.
• Introduce a penalty to alternative chains based on the depth of the fork. This makes it harder for an attacker to do mid size reorg.
