There are several ways to upgrade LibreOffice, including the Online Update option available in the LibreOffice application. Any method should be acceptable, but a method has been suggested here as the most reliable way of creating a clean installation at the targeted version for upgrade. This is especially important when using LibreOffice in a carefully controlled environment, e.g. on a production system.

Uninstall the current version of LibreOffice using Windows Add or remove programs
Install the new version of LibreOffice using the standard installation instructions: Install LibreOffice | Windows
Remember to check whether configuration of the integration of PhixFlow with LibreOffice needs to be updated: Configuring PDF Conversion

Linux

If installed from the repository as recommended (see Install LibreOffice | Linux), LibreOffice should be upgraded as part of a dist-upgrade process, not individually.

Check which version you will get from upgrading:

sudo apt update
sudo apt-cache policy libreoffice

If this is not the latest version, you may need to re-add the LibreOffice PPA (this is added for installation, but some operations on linux servers will remove PPAs):

sudo add-apt-repository ppa:libreoffice/ppa
sudo apt update
sudo apt-cache policy libreoffice

Then proceed with the upgrade:

sudo apt update
sudo apt dist-upgrade
