Hello, I just noticed a urgency discrepancy for Stunnel 5.12 on the website (both of these links are under the Downloads section):
https://www.stunnel.org/versions.html - shows 5.12 urgency as HIGH https://www.stunnel.org/sdf_ChangeLog.html - shows 5.12 urgency as LOW
I don't know if it makes a difference with 5.13 available (assuming urgency = LOW) but I think 5.12 should have urgency=HIGH.
Thanks, -Rob
