I noticed today that GetTempDirectory() returns a different path than it did in CF5 and prior versions. In CFMX it returns cfusionmx/runtime/servers/default/SERVER-INF/temp/wwwroot-tmp.
I'm not quite sure why this is, because the java System property java.io.tmpdir = C:\WINNT\TEMP\ on my machine. I would have thought they would use that value as CF5 does.
Anyways I thought it should be pointed out since it is not in the release notes. I'm not going to report it as a bug, because I don't think it makes much difference what directory GetTempDirectory() returns as long as its a temp dir.
