As soon as I bring up a 0.4.2 node (from svn, not official release), I start getting the following
on seeds (all other nodes are 0.5 trunk):

java.io.EOFException
	at java.io.DataInputStream.readFully(DataInputStream.java:180)
	at java.io.DataInputStream.readUTF(DataInputStream.java:592)
	at java.io.DataInputStream.readUTF(DataInputStream.java:547)
	at org.apache.cassandra.net.HeaderSerializer.deserialize(Header.java:160)
	at org.apache.cassandra.net.HeaderSerializer.deserialize(Header.java:133)
	at org.apache.cassandra.net.MessageSerializer.deserialize(Message.java:155)
	at org.apache.cassandra.net.MessageSerializer.deserialize(Message.java:143)
	at org.apache.cassandra.net.UdpConnection.read(UdpConnection.java:143)
	at org.apache.cassandra.net.SelectorManager.doProcess(SelectorManager.java:135)
	at org.apache.cassandra.net.SelectorManager.run(SelectorManager.java:98)

down, upgrade, restart all.
