Features
LibreOffice Portable is a full-featured office suite that's compatible with Microsoft Office, Word Perfect, Lotus and other office applications. It's easy-to-use and feature-rich, performing nearly all of the functions you'd expect in an office suite, but at no cost. Additional functionality including the Base database and document creation wizards is enabled by installing the jPortable portable Java runtime environment. The portable version comes with its own MSVCRT runtime in order to work on systems without local installed rumtime too

Version Note:
3.4.1 should be safe for most users, but will install to a separate LibreOfficePortableTest directory for now. LibreOffice 3.4.2, available at the end of July, will target enterprise deployments and will then be the main LibreOffice Portable version going forward.

Which languages?
- The standard includes support for Chinese (Simplifed and Traditional), Dutch, English, French, German (Homepage), Hungarian, Italian, Japanese, Korean, Polish, Portuguese (Portugal and Brazil), Russian and Spanish.
- The All Languages includes all 57 languages supported by LibreOffice.
An experimental option during installation allows you to remove extra language templates, dictionaries, etc but may require launching LibreOffice twice on first run to complete the process.

- The second version of the newer 3.4 family, targeting both private individuals and enterprises. LibreOffice 3.4.1 fixes several bugs that affected the previous version, and can be safely deployed for production needs by most users.
- Large enterprises deploying LibreOffice on desktop PCs, are still recommended to deploy LibreOffice 3.3.3, which has been tested over several months by thousands of people worldwide, and are encouraged to call on professional support services. LibreOffice 3.4.2, available at the end of July, will target enterprise deployments.
- Recognizing that large enterprises and conservative users have special needs, The Document Foundation has decided to provide two different versions of the software, so as to garner to the needs of power users looking for the latest enhancements while still catering to the priorities of more-prudent users who prefer stability over availability of new features.
- Versions announced as stable can be safely deployed in work environments, as bugs might hamper individual features but won’t have an impact on the overall quality and security of document production.
