v0.4.9

Added

• A node's heartbeat now reports which stages it is executing, so a brief disconnection no longer risks a running stage. (#225)

Fixed

• Repository setup no longer blocks the node while it runs, so a long install cannot make a busy node look unresponsive. (#224)
• A node now declines a remote update while it is running stages, instead of installing one it cannot restart into. (#224)
