The version currently in Manjaro Stable is 24.2.5.
No, this is not how it’s handled in Arch-based distributions. If you keep your system up to date, then you will be on the latest version of everything.
That said, there was another major Stable Update today, as you can read here… 
Subscribe to notifications for the Stable Updates category, and be sure to always read both the first and second post of the thread. The first post details the changes, and the second post gives you a heads-up on the potential issues and how to work around them.
I would advise you to update your system now…
sudo pacman-mirrors -f && sudo pacman -Syu
Do this from a tty while completely logged out of the graphical environment.
After that you can update your AUR packages with pamac.
pamac update --aur --devel
Note: Do not forget to merge your .pacnew files after rebooting. See System Maintenance - Manjaro.
