The Document Foundation has released LibreOffice for 3.x branch, LibreOffice 3.6.5. This brings quite a big number of bug fixes across the area and it's intended for those who are looking for a stable office suite.
Meanwhile, the development for LibreOffice keep going. They also released RC3, which should be marked as final version if there are no showstoppers in this RC. The 4.0 release is planned for this February and it will be on time. Lets just wait for some days before the final version gets published.
For enterprise users, it's recommended to stick with 3.6.x branch until LibreOffice 4.0.2 gets released to avoid some regressions which is normally found on major new releases
