The Document Foundation released a new version of the LibreOffice suite, bringing ready-to use packages for Linux, Windows, and macOS. One of the interesting changes in this release is the built-in QR code generator.
LibreOffice needs no introduction. This open source office suite is the de-facto standard on Linux as well as a good alternative for Windows users who can do with basic editing without the complicated formatting and feature bloat of Microsoft Office. The price being free is yet another killer feature of LibreOffice.
