How to upgrade the Denarius v3.3.9.11 wallet, QT or Daemon, now with DDNS, decentralized Domain support. The idea here is to not force a mandatory protocol upgrade, we can swap the wallet and either sync from block 0, or use chaindata. This will be wordy, but its not too many steps.
Latest binaries - https://github.com/carsenk/denarius/releases
First stop wallet and backup wallet.dat somewhere safe, like a USB thumbdrive.
Download the v3.3.9.11 binary or compile from source. Unzip to wherever you normally run the binary from. For Windows you just replace your existing Denar
