"Allows you to rename the materials or objects in your scene in various ways (prefix - total rename - append number - etc). Originally called MaterialRenamer - now the name has changed and functionality includes the ability to rename selections of objects as well.
version 1.50 Changed the UI pretty dramatically. Added all uppercase all lowercase option. You can now rename point cache's and materials in current matlib."
The only major differences between script packages are slight version compatibility issues - there are no new scripts added between the 3 packages.
