While releasing the 7.0 major version update, the Document Foundation also provides LibreOffice 6.4.6 version for all platforms, which is the sixth maintenance version of the LibreOffice 6.4 series. It contains several bug fixes and improves documentation compatibility and interoperability with other productivity suites.
The Document Foundation says LibreOffice 6.4.5 is optimized for production environments and can be used by even more conservative users, as the release includes months of bug fixes. Users of LibreOffice 6.3.6 and previous versions should update to LibreOffice 6.4.6, as version 6.4.6 is currently more suitable for their productivity needs and stability.
