Release Notes of ufdbGuard v1.33

Version 1.33 of ufdbGuard was released to introduce various new features and fixes.

ufdbGenTable and ufdbguardd support URLs with UTF8 characters in the domain, path and parameters
new keywords ipv6 and ipv6list can be used in source definitions,
new keywords ipv4 and ipv4list replace the existing keywords ip and iplist but for backward compatibility the keywords ip and iplist remain functional,
the certificate of sites used by the ucweb browser (which circumvents URL filters) are detected,
ufdbgclient has a new -m parameter to use multithreading and improve performance considerably,
the file ufdbguardd.pid is made world-readable,
the new keyword ufdb-log-url-details controls if URLs in the log file have parameters or not.

for URL tables with over 2000 URLs and more than one URL with the same (sub)domain, ufdbGenTable may produce an incorrect URL table,

sometimes ufdbguardd had false positives with Tor proxy detection on port 443,
failed probes for :443 were not properly cached and resulted in too many probes for IP,

implicitly allowed URLs were logged with category "any" instead of the correct category ID,
ufdbGenTable uses less memory,
the feature "block-bumped-connect on" never blocked a CONNECT request.
