Hello HU76,
Stay tuned with Ebox in general. I have been following Ebox for the past two years. I started using it for the past one year when I felt that is stable and feature-rich enough for my use. Calvo has said that there is going to a release immediately. I dont know whether he mans 1.5.9 or higher. Anyway we have to wait.
After all, we do not pay them for the dev, right? If you can opt for the supported versions, you have every right to complain.
As of now, they are doing REALLY wonderful work.
Yes, as you have pointed out, you can stick with LTS10 and proceed. In fact, that is what I tried when I saw that 1.5 is not stable enough. But I am not a Linux Geek and integration becomes a HELL of a job as the features go up.
Regards
