NeoOffice 3.3 Patch 6 New Features
In late April 2013, the NeoOffice engineers released NeoOffice 3.3 Patch 6 with the following new feature. The latest patch can be downloaded from the NeoOffice patch download page:
 Ability to open LibreOffice password protected files
The NeoOffice engineers recently found that in LibreOffice 3.5 and higher, LibreOffice saves password protected files using a different encryption algorithm. NeoOffice's underlying OpenOffice.org 3.1.1 code does not support the encryption algorithm that LibreOffice now uses so any password protected files saved in LibreOffice 3.5 or higher could not be opened in NeoOffice.
The NeoOffice engineers have implemented custom code that can read the encryption algorithm that LibreOffice now uses. With this custom code, NeoOffice users can now open password protected files that were created or edited using LibreOffice. Saving password protected files in NeoOffice still uses the same encryption algorigthm as before so NeoOffice password protected files can be opened in OpenOffice, LibreOffice, and older versions of NeoOffice.
