Thanks for testing, guys!
The things being removed all moved to the Fiji-Legacy update site.
The update is from 1.51h to 1.51n. This upgrade is actually a little problematic, because the 1.51n version of ImageJ 1.x is "too new" for the final Java-6 version of
ij1-patcher to fully cope with (you'll see a big stack trace relating to
YesNoCancelDialog and how code couldn't be patched). So I'd suggest not upgrading, actually. But it is not a huge deal, since things will largely still work either way.
