I'm reluctant to update plink. They have a time machine on their server
so you're never sure if you really get the latest release.
See this thread for details:
http://groups.google.com/group/tortoisesvn/browse_thread/thread/f2a890f517b835bc/b19072c65874f1bd?lnk=gst&q=0.60#b19072c65874f1bd

That said:
if you have a patch against plink 0.60 (if it really *is* 0.60 and not a
beta), please send it here.
