This is the v0.12.0.0 point release of the SuperiorCoin software, and it is part of the v0.12 network wide update. This major release is due to the April 10th network update, which in turn increases the minimum ring signature size, sorts inputs so as not to leak wallet choice by inference, slightly changes the proof-of-work algorithm to prevent DoS attacks by ASICs and changes to a time based dynamic block reward. This release of the software presents a number of major improvements to SuperiorCoin, as well as a large set of bug fixes.
Some highlights of this major release are:
Time based dynamic block rewards
