As the changelog says, one more unurgent fix (patch 5 of this sereis) has added
on top of the v1.

Maybe my versioning scheme is confusing you.  I increase minor version when it
is purely for findings from Sashiko and if the change seems not really big.  I
do so because I realized it is easy to get version number large in short term
when I respect Sashiko, and it may look confusing for some people.  Maybe a
better approach is running Sashiko in my local, but I don't have AI setup in my
development environment...  Let me know if this only confuses and bothers you
and you have a suggestion.
