When downloading from your site today I discovered that the latest version is 1.3.8. Joomla Updater gives no indication of this, probably because your file nordmograph.com/extensions/updateserver/mod_vmsynthdashboard-update.xml still says
<version>1.3.5</version>. Could you please fix this?
Also it would be very nice if you could put up a changelog, so we can see what's new since the former version (in our case 1.3.5).
You promised me last March that you would do this... (nag, nag).
