The Document Foundation has released LibreOffice 3.4.2 and marks it as "Enterprise Ready". Even though it's just a monthly update from the 3.4.x branch, it's a considered important milestone as the developer fix some annoying bugs that prevent it to be marked as rock solid release. Those bugs were mostly incompatibility with Microsoft Office products which is still considered de facto for Office Suite around the world.
As Italo Vignoli said in the announcement, LibreOffice 3.4.2 is the result of the combined activity of 300 contributors having made more than 23,000 commits, with the addition, deletion or modification of around five million lines of code. It's really a community and enterprise effort to bring LibreOffice become much closer to reach Enterprise level. You can take a look on the chart below.
Next LibreOffice release will be ready on August and that will be LibreOffice 3.4.3. For now, let's just enjoy LibreOffice 3.4.2
