Version 1.33.7 is a bugfix release and has the following fixes:

• Implement a workaround for a fatal bug in gcc 4.x when -O3 is used, that causes ufdbguardd to dump core. Users who use the RPM packages do not suffer from this gcc bug since -O3 is not used.
• The pidfile parameter was not used and the pid was written to the default pidfile.
• On blocking https sites, the final block page was not shown without ssl_bump.

ufdbGuard v1.33.6 fixes a bug that was introduced in version 1.33.5.
The fix is for ufdbGuard blocking all HTTPS-based URLs when HTTPS probing is used, i.e. the parameter check-proxy-tunnels has a value other than off.

ufdbGuard v1.33.5 is a bugfix release with an important fix for a crash during database reload.
This release has the following fixes:
* ufdbguardd may crash during a database refresh,
* empty pass statements in acls may cause a crash,
* SSH tunnels were detected but access was not blocked,
* sometimes the SSL/TLS certificate was not checked to be signed by a CA,
* skip acls with "pass any" if the source has the continue flag set.... read more

ufdbGuard version 1.33.3 is a bugfix release and has the following fixes:
1. ufdbgclient truncates Squid request lines to 8K which means that very long URLs cannot be filtered,
2. ufdbGenTable erroneously warned about URLs inside a comment,
3. when 'evaluate-and' and IPv4/6 is used in a source definition, the source may not matched,
4. ufdbguardd did not accept the IPv6 address '::'.

A lot of sites still use version 1.32.x which has a bug on systems that have a high load or are slowish and prevents ufdbguardd to load a fresh URL database. If on your system there are crash reports in /tmp like (see output of ls -l /tmp/*crashreport*), it is highly recommended to upgrade to 1.33.3.

New Functionality

• 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.... read more
