The largest changes that exist in version 0.0.0.4 of CryptoCollaboration is the support for Microsoft word documents as opposed to just simple text files, as was the case in version 0.0.0.3. If you want to view the changes that were made to the code outside of the support for Microsoft Word documents, view the 0.0.0.3 release.
For a screen shot diary regarding the support of Microsoft Word documents, see the home page of the project site, which details the operations.

The initial documentation for installation and operations will be updated accordingly, however for the time being is not my focus. However, it is coming.
