Release Notes: Support for OpenLDAP based authentication was fixed. Support for NTLM authentication was further optimized for speed and performance. The maximum number of idle connections to the LDAP server is now ensured to never exceed 5% of MAXTHREADS. Failure to close connections opened to the LDAP server, because of a logical flaw in accounting, has been fixed.
Release Notes: Improved mechanisms for addressing CLOSE_WAIT related problems. This release can reclaim both half-open and half-closed sockets (CLOSE_WAIT state connections) and reuse them for both inbound and outbound connections. A logical flaw that caused a memory leak on application of profiles under certain conditions is fixed. The cProfiles feature has been enhanced for speed. Depending upon user configuration, resolution speed will be about 30 to 70% faster. The init script has been improved, and a few more parameters have been made tunable via startup.conf.
Release Notes: A new parameter, OVERLOAD_FACTOR, has been introduced. A logical flaw in cache cleaning operation has been traced and fixed. A logical flaw in logged cache object size has been traced and fixed. The design of cProfiles has been modified to allow it to query for an almost unlimited number of Web sites simultaneously. Failure of the MD5 integrity check for cached objects has been corrected. A logical bug while updating or modifying the entries in cache has been corrected. Dynamically generated objects are not cached now. Memory requirements have been tremendously slimmed down.
Release Notes: This release fixed bugs where SafeSquid failed to discard cached objects from memory for indefinite periods when the memory usage exceeds 100% and connections were not established when the network latency was more than 100ms.
Release Notes: New command-line options were added. "-t (MAXTHREADS)" allows you to control the maximum number of concurrent threads that may be started within any instance. "-z (STACKSIZE)" defines the thread_stacksize of each of these stacks. Improved compatibility with NPTL has led to sacrificing of compatibility for kernels older than 2.6. This practically eliminates segfaults (crashes), and provides very high system integrity in the face of DDOS attacks. The installation system was improved. The init script was improved.
Release Notes: This release adds many small bugfixes and feature improvements.
