If 3.9.2-50 is not showing up as available it could be that your stable updates subscription has expired. You can always check on it’s status via our new ‘self service’ Appman Web facility:
The Changelog for current Stable channel is available in the following forum thread:
It’s not been properly announced here on the forum just yet and was created to address some inconveniences that we had outstanding. Contact me via PM here on the forum if their is an issue with your subscription as their have been some known issues with our move to Appman. In a Private Message we can freely discuss you Appliance ID and activation code if required and so more easily get things sorted.
Take a look at Appman and check your subscription is still running and that for each subscription the associated ‘computer’ has the correct Appliance ID (you can change it yourself in Appman if not). We can continue the Appman / subscription discussion in a PM if you end up not being able to get that update for whatever reason.
Hope that helps and lets carry on the update issue in a PM if you find your subscription and Appliance ID all look to be OK in Appman.
