This release includes Dispensers and Sweeps (Protocol level, single message) support (effective immediatly).
Update should be done ASAP as the rules are already active. Bootstrap download or a full reparse is required as there's already some dispensers active in mainnet and old nodes won't pick them up (and diverge).
For manual installations:
cd federatednode/ fednode stop git pull sudo rm -f data/counterparty/counterparty.* fednode update fednode rebuild
