Today LibreOffice 3.3 Final has been released. This is the first stable version of LibreOffice. It underwent a three-month beta and release-candidate phase, and is considered safe for production use.
The following notes apply:
This release is bit-for-bit identical to the Release Candidate 4, so you don’t need to download or reinstall if you have that version already.
The distribution for Windows is an international build, so you can choose the user interface language that you prefer. Help content is available via an online service, or alternatively as a separate install.
For Windows users that have OpenOffice.org installed, we advise to uninstall that beforehand, because it registers the same file type associations.
If you run Windows 2000, you may require this update before being able to install LibreOffice.
If you run Linux, the GCJ Java variant has known issues with LibreOffice, we advise to e.g. use OpenJDK instead.
There are a few non-critical issues still contained in this release, which will be addressed soon with upcoming bugfix versions:
If you install third-party extensions that bring their own help, you may only be able to view that after installing the separate helppacks on Windows.
On Windows, Python-based extensions cannot be registered with LibreOffice.
To install LibreOffice 3.3 Final on Ubuntu follow this method.
