StackRegent 0.17.17
SSL/TLS: mail (SMTP, IMAP, POP3) and FTPS present one certificate for the whole server. On a website's SSL/TLS page, Certificates of mail and FTP now lists only server pool certificates and explains this; choosing a website's own certificate gave an unclear error. Also includes 0.17.16: on Windows Server 2016 the installer installs .NET Framework 4.8.
How to update: in the administrator panel, open Tools & Settings → Updates, click Check now, then Install. Websites, mail and DNS keep running while the panel updates. SHA-256 of the package: bc8edd0f7aa8ac37942f4c12e1e11a891d485b6af882c39bf0498d001305b1c7
