v1.5.10 - Flux Difficulty Algorithm - Hard fork required

This is a hard fork release so you will need to upgrade before block 8000.

The previous hard fork was activated without any issue but the Digishield difficulty algorithm is proving to be inadequate. We have coded up a new solution called the Flux Difficulty Algorithm. This is a minor adjustment to Digishield so that it implements throttling which will eliminate the peaks and troughs of the difficulty chart. This works by making an extra comparison with the previous block time and throttling the rate of change. The current Ethereum difficulty algorithm works using the approach of looking at the time of the previous block.

We have been testing this for a few days in our local Testnet and the results look good. We do not anticipate any issues and we are in close conversation with our pool operators.

Thank you for your support and understanding.
