Looks like a lot of effort has been put into this release, especially under the hood. I switched from OpenOffice to LibreOffice recently due to much improved docx import in LibreOffice, and I see that the 4.2 release adds further bugfixes to docx import. It looks like OpenOffice have really dropped the ball on this...docx (and other MS Office import) is really important to anyone who sends and receives documents from the outside world.
