Alright, I think this is a neat change.
kdesvn-build has supported an automatically generated symlink in the log directory called latest for awhile now, which puts you in the log directory for the last build run.

Now, instead of symlinking latest to the last build run, latest holds a directory of symlinks.
Each symlink is named after the module concerned and links back to the last build run for that module.
That way you always have easy access to the logs for the last build run of a module without having to run find or anything crazy.

You should find that using it is effectively the same unless you have tools of your own that depend on $logdir/latest being a symlink.
