The first one is actually a fix from 1.8.2. The line is clearly unreachable because you have a "return" statement above it which is guaranteed to be called, since either the "if" or "else" code block will be executed, so the "PLUGIN_CONTINUE" should not be there - remove the entire line.

The other warning is telling you that in 1.9 there's a new forward "client_disconnected" which is a replacement for "client_disconnect" - this one is deprecated now because it doesn't catch all situations when a client disconnects, so you should replace it with the new one.
