We're working on an on-chain voting strategy similar to how mining works, where anyone can cast a vote proportional to the amount of Bitcoin burned. Similar to how Bitcoin upgrades, a new feature will activate if a certain threshold (e.g. 80%) of votes consistently request its adoption over a given time interval (e.g. a couple weeks).
Until then, we will publicly announce the availability of new software, with the promise that each release will bring highly-desired features to make upgrading worth the users' whiles.
