v1.18 2015 Sept 12th p0
Notable changes from previous version:
WDT can now resume interrupted transfer based solely on file size based an examining the directory tree (as opposed to previously using it's own transfer log)
If you are using wdt on single disk systems use that mode and disable blocks mode, if you are using flash continue to use the transfer log and the block mode which are most effectives when doing simultaneous IOs is not expensive (like flash, unlike single disk systems)
