- Remote Command Execution Vulnerability allowed_comapps.php
- Uniform memory report over distros (Set Linux as default)
- Some GUI tweaks
- Updater import user style(s)


meterN 1.2		20-07-2019

- New : Add json dataset
- Change : IEC62056 dataset rewrited
- Change : Removed state & value mode for live values
- Some usual byte cleanup

	In order to always simplify, removed "state & value" mode option. The live command can return anything, like the previously value mode does.
	If you want to disable, just leave empty the command field.

	If you previously used 'state' mode, it won't show 'On/Off', you need to change your com app to return 'On' or 'Off' rather than 1 and 0.
	You can also trick your com app to return HTML tag to show colors like this :
	meterid(<font color='#228B22'>On</font>*)
	meterid(<font color='#8B0000>Off</font>*)

	You will have to save indicators + meters & sensors configurations.

In other words, if you have a meter that need an index correction, let's say you read 100 liters and mN return 110 liters :
You correct via 'Redefine' then, change your daily values and remove 10 liters

You can also use "Change daily value(s)" to fill your missing data.
