In preparation to the soon first block producing epoch (granted after some delays) I have modernized software to be as up to date (for example only latest long term support distros) and had a 2nd pass with a critical eye on security. We also made several optimizations so everything is as rigged and ready as can be. Security is certainly nothing I will ever be relaxing on and I am constantly trying to evolve in this area to have as much safety as possible. While I wish I could detail all the new security enhancements I have added the fact is that another security measure is to have as much hidden information as possible when it comes to security measures. Hopefully this is understandable.
