No, I think that is sufficient.
You realize that 0.7.22 was end of life years ago?
So whatever bugs are in there, they remain.
We fixed few bugs over the past seven years ...
some of those fixes should be relevant for your issue.
We are currently at 8.4.4
(or 8.3.16, if you insist on being conservative),
with all new and improved bugs now ;-)
