NodeHello
This is a message of the Freenet Client Protocol 2.0 (FCP 2.0).
It is sent by the Freenet node to a client program in response to a ClientHello message.
The node tells us what version it is, what protocol version it's using, whether testnet mode is enabled, and how many and what compression codecs are currently supported (this is important with the StartedCompression message).
Example (from build 1231)
