Stacks is undergoing a mandatory network upgrade with the release of stacks-core 4.0.1. This is a consensus-breaking hard fork that activates a new protocol epoch (Epoch 4.0) introducing Clarity 6 and Bitcoin Stacking as described in SIP-044 and SIP-45, respectively. All node and signer operators must upgrade before the activation height. After activation, nodes running 4.0.1 and nodes running 3.4.x will diverge.
