Release notes:
* This release is bit-for-bit identical to the 3.6.4 Release Candidate 3, so you don't need to download or reinstall if you have that version already.
* The distribution for Windows is an international build, so you can choose the user interface language that you prefer. Help content is available via an online service, or alternatively as a separate install.
* For Windows users that have LibreOffice prior to version 3.4.5 installed, uninstall that beforehand. Otherwise, the upgrade to 3.6.4 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.
* A full list of annoying bugs is available from the wiki.
