An anonymous reader writes "Still the most popular open source office suite, Apache OpenOffice 4 has been released, with many new enhancements and a new sidebar, based on IBM Symphony's implementation but with many improvements. The code still has comments in German but as long as real new features keep coming and can be shared with other office suites no one is complaining." The sidebar mentioned brings frequently used controls down and beside the actual area of a word-processing doc, say, which makes some sense given how wide many displays have become. This release comes with some major improvements to graphics handling, too; anti-aliasing makes for smoother bitmaps. In conjunction with this release, SourceForge (also under the Slashdot Media umbrella) has announced the launch of an extensions collection for OO. Extensions mean that Open Office can gain capabilities from outside contributors, rather than being wrapped up in large, all-or-nothing updates. You can download the latest version of Apache OpenOffice here.
