LibreOffice 3.5.5 (2012-07-11)
The Document Foundation today announces the immediate availability of LibreOffice 3.5.5, the current version of the free office suite.
This release fixes a number of bugs and further improves the stability of the software, making it the best version available for corporate and enterprise adoption. Among the changes are improvements in Calc, Impress, in the handling of fonts as well as enhancements with regards to importing and exporting third-party formats.
* For Windows users that have LibreOffice prior to version 3.4.5 installed, either uninstall that beforehand, or upgrade to 3.4.5. Otherwise, the upgrade to 3.5.4 may fail.
* For Windows users that have OpenOffice.org installed, we advise uninstalling that beforehand, because it registers the same file type associations.
* If you run Windows 2000, you may require this update before being able to install LibreOffice.
* If you run Linux, the GCJ Java variant has known issues with LibreOffice, we advise to e.g. use OpenJDK instead.
* LibreOffice contains all the security fixes from OpenOffice.org in 3.3.0, and perhaps more as a side-effect of the code clean-ups.
* Microsoft Office 2010 will complain that ODF 1.2 and extended documents written by LibreOffice 3.5 are invalid (but opens them still). This is a shortcoming in MSO2010 only supporting ODF 1.1, please see here for further details.
