 stunnel has been updated to version 5.23:
 ** New features
 * Client-side support for the SOCKS protocol. See
 https://www.stunnel.org/socksvpn.html for details.
 * Reject SOCKS requests to connect loopback addresses.
 * New service-level option "OCSPnonce". The default value is "OCSPnonce =
 no".
 * stunnel.cnf was renamed to openssl.cnf in order to to prevent users from
 mixing it up with stunnel.conf.
 * The ca-certs.pem file is now updated on stunnel upgrade.
 * Inactive ports were removed from the PORTS file.
 * Added IPv6 support to the transparent proxy code.
 * Bugfixes
 * Compilation fix for OpenSSL version older than 1.0.0.
