BOSCore v3.0.7 Release Notes

Change Description

BOSCore support EOSVM and strengthen the security.

Enable EOSVM with:

WARNING:

As from the issue, as for BP signing and API nodes, the eos-vm-oc-enable = false should be used to avoid it can be too faster to left other node in the dust.

API settings must match BP settings. CPU calculations should be the same for public API and BPs.

for other nodes, eos-vm-oc-enable = true can be used.

1. Support EOSVM
2. Consolidated Security Fixes for eos-vm
3. Upgrade create_snapshot API to keep the compatibility
4. Upgrade Dockerfile to support EOSVM
