Therefore the The Document Foundation decided to provide the latest stable version also as Flatpak. We have Flatpak enabled by default, but not activated in Pamac. So go to settings, activate it and do a reboot of your system. As an alternative you may use the terminal console and issue flatpak install flathub org.libreoffice.LibreOffice to install LibreOffice.
flatpak install flathub org.libreoffice.LibreOffice

If having Flatpaks is not your cup of tea and you want a lower footprint, there are also AppImage solutions. Simply download the AppImage file you need and make it executable. Having AppImageLauncher installed will do that automatically for you and even adds it to your Start-Menu.
The Manjaro Official Repositories have libreoffice-fresh at 6.4.5 and libreoffice-still at 6.3.6.
As far as what the Document Foundation is considering “Still” and “Fresh”, They just released 7.0.0 on August 8th, so at that time the old “fresh” was now considered stable enough to become the new “Still” and the development of new features will continue in the fresh version.
So if you had visited their website 2 weeks ago there wouldn’t be anything confusing about it. In a few weeks when the packages have gone through the testing process and are part of stable it will once again be in sync with what the document foundation is publishing as the latest versions. That is going to be the case with EVERY piece of software developed by any developer. Just because a developer releases their “new shiny new version of XYZ Plus Ultimate edition” doesn’t mean it is instantly in the manjaro stable branch 30 seconds later.
The new versions just take some time to test before they can be rolled into the various distributions “Stable” release. Especially when you are talking about what is some people’s main productivity suite for getting work done it isn’t something you want to blindly jump into. But for those that want to live on the bleeding edge or they just can’t live another second without “Implemented support for semi-transparent text in Writer.” or one of the other new features those people have the options now since the manjaro team has integrated all of these other package choices for you so you can install the latest version from the developer as a flatpak or appimage as discussed above. The snap version isn’t on the new version yet either.
Personally there isn’t a single feature in the new 7.0 that I need or care about to move me from the reliable still branch that I’m currently on but everyone has their own level of stability or features that they need when it comes to an office suite.
