The Squid HTTP Proxy team is very pleased to announce the availability of the Squid-3.4.6 release! This release is a bug fix release resolving memory leaks and portability issues found in the prior Squid releases. The major changes to be aware of: * Regression logging custom time formats The previous version contained a regression in log output when log format codes for time display were used. The native unis timestamp being displayed instead of the configured time format. This is now fully resolved. * Various memory leaks Previous Squid have all suffered from small memory leaks during reconfigure. Durign normal operation they are not a problem, but for installations reconfiguring frequently they can add up to a lot of memory. The bulk of this releases change is patches resolving several of these leaks. Not all leaks have yet been fixed and some have been held back to the next Squid series due to dependencies. The largest of these leaks have been noted in SSL builds. * Bug #4065: round-robin neighbor selection with unequal weights This fix changes the behaviour of Squid when re-balancing or reconfiguring weighted-round-robin on peer connections. Previously each peer would be used once before the weighting would take effect. Now weight is applied immediately. This results in much more strict balancing in accordance with the weights, and less unnecessary connections to low weighted peers. There remains one un-resolvable issue when greatly differing weights are used: the lowest weighted peers may never be used at all now, depending on the traffci load and frequency of re-balancing. * Portability improvements As always we seek to support as many popular operating systems as possible. This release contains several updates to fix build issues and increase the supported operating systems and CPU architectures. All users of Squid-3.4 are encouraged to upgrade to this release as time permits. All users of older Squid versions are encouraged to upgrade as time permits. See the ChangeLog for the full list of changes in this and earlier releases.
