"Anyone running the Feathercoin clients recently will have noticed that we are picking up CAlerts from the Litecoin network. Feathercoin 0.6.4.2 has a fix to disable these alerts. Alerts were introduced in Bitcoin 0.3.10 some 3 years ago now when Bitcoin was still young. This feature is somewhat dangerous as it allows individuals to send text to be displayed in everyone's clients.
Please download the new client from the homepage.
