Unfortunately there are 2 version numbers for the apps in the truenas app catalog. The "version" which is what you see in hexos, this is just the iteration of the truenas docker app which has nothing to do with the overall application which is also called "app version"
you can see both of these numbers in the truenas interface if you would like but here is a screen shot
My "version" is 1.10.12 but that is the same thing as "app version" 2.2.3
so we are not actually behind.
i totally get the confusion though and ill be sure to bring it up with the team.
Just to clarify a few things
Truecharts is a third party app store that afaik shut down and was never compatible with hexos
All the apps you see come from the Truenas apps market which i believe is first party to truenas
HexOS unfortunately does not have any control over app versions (as much as i wish we did for troubleshooting), this is all truenas
