Hi Victor,
thanks for the response. Unfortunately, this holds true only for distros
where we have complete control over the stack (only Win, I believe). On
Debian, as in my case, packages get updated all the time, so we really
have no choice. I acknowledge the issues with saga changes; on the other
hand, supporting newer versions on more context will help us spotting
issues and fixing them earlier.
Of course, the alternative is to fork saga and keep and internal stable
version. I noticed, however, that currently there seems to be more
activity than in the past, so forking will be bad:

All the best.
