The LibreOffice team is testing the first release candidate of version 6.4, which is set for release at the end of January.

What's new in version 6.4? There are numerous fresh features; most are small, but they do include the ability to insert QR codes into any document. The Generate QR Code feature lets you enter a hyperlink (or any text) and generate a QR code with four options for complexity. A low complexity is better for long URLs while high has better error correction if there are errors in reading.
