Release notes:
* This release is bit-for-bit identical to the 4.0.0 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.
* Our Windows binaries are digitally signed by The Document Foundation.
* For Windows users that have OpenOffice.org installed, we advise uninstalling that beforehand, because it registers the same file type associations.
* If you run Linux, the GCJ Java variant has known issues with LibreOffice, we advise to e.g. use OpenJDK instead.
* LibreOffice 4.0 drops a few long-deprecated features, including support for legacy binary StarOffice files, export to legacy Word and Excel (version 6.0/95), and legacy ODMA document management.
* Some menu entries have changed or added. If you miss something, that may be due to the use of customised menu settings from your previous LibreOffice installation.
* This version still contains a few annoying bugs, as listed here. Specifically, the German Duden Korrektor extension needs a manual fix.
