Well, I'am actually in progress of figuring things out on my side.
However, I experience slowness at times. Also: even if regressions are
extra-ordinary events, it still does not feel right that they take so
long. At least I want to try to understand what is going on there.

Silly me. You are right. Maybe I should volunteer as maintainer and as
first act copy v1.3.3 tp v1.4.0 and declare it stable ;)

For my "slowness" experience this may very well be the problem, at the
moment I'm running btrfs. However, as I'm right now replacing the backup
hardware this would be the time to change something. We will see.

Many thanks for your feed-back,
