Wanted to see what differences are. Not sure how long it will be until update in dnf.
Just got email that stunnel 5.63 was released.
Downloaded and ran ./configure and make with default settings.
Compared output of -version for the 5.63 and 5.62. Most items same.
Note sure what differences are or why. Change in defaults or changes redhat makes?
