LibreOffice 3.3.0, announced on Tuesday, is the first milestone release of the open-source productivity suite from The Document Foundation since it split from the Oracle-led OpenOffice consortium in September. The release brings new features as well as popular options found in OpenOffice 3.3, according to the foundation.
Among the new features in LibreOffice 3.3 are the ability to import and work with SVG graphics files, and easier formatting and navigation tools when using Writer, the word-processing component of the package. There are also bundled extensions for importing PDFs, making slide-show presentations and other tasks.
