Domoticz

For Domoticz it is shown in the upper left corner of the Dashboard which release is applicable.

If you have one or more configurations a long time in operation, after so many upgrades one of the aspects you tend to forget is which version of O.S. is applicable.
Through a command at Putty's CLI ist is easy to find but is not the first aspect to mind if an upgrade is due.
Recent experience triggers to ease the way to check.

In category 'nice-to-have', would it be possible to add in that upper left corner a similar line indicating which O.S. is 'under the hood'?
If in the alert-for-upgrade a mandatory relation with an O.S. would be mentioned, then it is quite easy to compare.
Leaves initiative/responsibility at the User, not requiring an underground check in the upgrade whether the O.S. is compatible:
obviously that latter function would be next level of nice-to-have ....

I think that should not be on the dashboard, but on the About screen.
A unexpected change from Stretch to Buster should be catched in the installation/upgrade file.
An upgrade should be prevented if it would knowingly fail.
A warning from the installation/upgrade would be nice. So people can choose.
The installation file already checks for dependencies.
How simple could a check for OS be added?
The same applies for the upgrade files.

In hindsight coming to same conclusion:
the Dashboard should not be cluttered by this kind of info.
One 'layer down' is also good place for such indications.
Python, dzVents already there.

Based on recent experience as reported in this forum, possibly another candidate to be mentioned for compatibility:
LuA 5.3

Yes I agree about lua, and possible other stuff.
It is easily added. I asked for that before, but until now nothing.
Hopefully due to the Buster disaster soon.
