Hi Oleksii,

sorry this review has been a bit delayed, I tested V3 in my setup and found no
practical issue. I'll post a few comments/remarks along the series.

Beside addressing pending comments, I suppose that the next step will be anyway
to address the upcoming changes in the new v3.2 BETA regarding support for
multiple type/value set/get operations as requested by Peng.

Thanks,
Cristian
