meterN0.8 is out, it's featuring the comparison section and correct some bugs. Read carefully bellow to update :
This release break up previous yearly csv but don't worry there is a converter. The new format is a clearer YYYYMMDD in data/meters/*csv.
You are also requested to move the comapps folder from meterN. It will ease further updates and it make it clear, once again, that meterN is not about com apps

Don't forget to recreate links : rm /usr/bin/mycomapp then ln -s /srv/http/comapps/mycomapp.py /usr/bin/mycomapp
You may also may need to chmod +x /srv/http/comapps/mycomapp.py
If you use previous 0.7.8: You can use the updater and follow the procedure.
If you use a previous version : backup your old directory, extract the new version into and import data/ and config/ files.
Then go into http://yoururl/metern/admin/convert.php
Bye
