I installed Xubuntu 16 and have the latest version of xfce 14.12. However, some of the applications of xfce4 are not the latest version. For example, my version of Thunar is 1.6.11, whereas the latest is 1.7. Software centre does not propose any upgrades.
As far as I understand, the developer could either upload the latest version to the software centre or create ppa. It seems that the developer didn't choose these options (by the way, I wonder what is the reason. It seems that many applications in software centre are outdated).
Do I correctly assume that the only way to install the latest version of xfce4 applications is to download them and install manually one by one?
