Please note the Alpha_30.1 version was released under the Objectify project: https://sourceforge.net/projects/objectify/
Currently Objectify is a secure file archive system. It can be used to store files in a disk partition, memory card, or into an encrypted file. It can also be used to hide files on a computer. I am planning to write some new documents, in the next few weeks, describing each of these in more detail.
The Alpha_30.1 release was to fix some problems in the Alpha_30 release. The Alpha_30 release made some major changes to how the data was stored on disk.
Please note that I am in the process of moving the project from the SourceForge New World OS project to the SourceForge Objectify project: https://sourceforge.net/projects/objectify. I am planning on moving the CVS to Subversion on the Objectify project after this release.
