Returns MD5 hash of the new file.

A String value.  

object.NewMD5

The NewMD5 Property syntax has these parts:

This property returns MD5 hash of the new file that will be downloaded. It represents (almost!) unique 16-byte information about the file. No two files can have the same hash - so you can use it to see if old file is, by any chance, same as new one, by checking at MD5 property too.

This information is received from your configuration file on the server.
