I'm running Hades 018. I have everything I want working perfectly (CrossEPG, ABM, DreamPlex, Setting, Custom Skin, RefreshEPG, CAM, PowerTimers, Samba Client/Server ... etc).
The receiver is bullet proof, no crashes, hangs or anything unexpected.
It's been like this for 1.5 years.
I have 2 GigaBlue Quad+ receivers at home. I've recommended the same receiver to others also and I've given them my EXACT image in the knowledge that it will be 100% reliable.
Every now and then I'll do an image backup and take a look at the latest OpenVix build but I normally do see anything extra I want/need over what I have in Hades 018.
How long can I expect Hades 018 to stay working? I don't use the feeds anymore to download plugins since I don't want to change the box.
From what I can tell, the only risk is ABM changes server side that require a client side update. Maybe there's more I'm missing (IMDB possibly too but I don't use that at all ... in fact it's disabled in my custom skin).
