Changelog

How to upgrade
⚠️ Make sure to back up your validator node before you make any changes.
From v0.0.1
Follow Upgrading a validator or a full node from v0.0.1 to v0.0.2 but use v0.0.3 instead of v0.0.2.
Or you can use @dbriggsie's Quicksync, which is a little more dangerous (more downtime) but way faster: https://forum.enigma.co/t/chainofsecrets-org-launches-quicksync/1467/5
From v0.0.2
sudo systemctl stop enigma-node
sudo dpkg -r enigmachain # might fail but this is okay
sudo dpkg -i enigma-blockchain_0.0.3_amd64.deb
sudo systemctl enable enigma-node
sudo systemctl start enigma-node
