For Solaris 10/x86, Solaris 8,9,10/sparc, and Linux, the MySQL clients and client libs have been upgraded to 5.0.18. Note that our MySQL server currently runs version 4.1.18, and we want to move that to 5.0.x in the future as well, but the clients must be upgraded first before we can move ahead with that. In case you're wondering, connecting to a 4.1.x server with a 5.0.x client will work fine.
