The only change in the Alpha_28.4 release is that disc logging can now deal with subdirectories on the disc. Prior to this all files had to be in root directory of the disc and there could not be any subdirectories.
Please note: I am in the process of moving Objectify (which is an implementation of some of my OS ideas which runs on top of another OS) to it's own project: http://sourceforge.net/projects/objectify. The CVS and release files are still under the New World OS project. There are a few old bugs also still under the NWOS tracker. The new bugs and Feature Requests are under the Objectify tracker.
Currently Objectify can store files encrypted and log the files on backup discs.
