The Squid HTTP Proxy team is very pleased to announce the availability of the Squid-4.3 release! This release is a bug fix release resolving several issues found in the prior Squid releases. The major changes to be aware of: * Bug 4885: Excessive memory usage when running out of descriptors When using some I/O select loops Squid can continue to allocate memory for client connections after it has reached maximum available FD limits. This release drops the memory to a fixed amount for each *_port regardless of how many client connections arrive. * Bug 4877: Add missing text about external_acl_type %DATA changes The external_acl_type directive changes to encompass logformat codes has a side effect on implicit %DATA parameters sent to the helpers. Previous Squid versions would elide this field sometimes if no data was contained - but only when implicit. Squid-4 will always send a value, using '-' when no data exists. This was omitted in earlier release documentation and caused some surprises to admin with custom helpers not fully supporting the current helper protocol. Any users of this directive with custom helpers written for older versions of Squid are advised to review what their helper is doing and ensure that it can cope with the helper protocol fields documented as 'optional'. * Bug 4716: Blank lines in cachemgr.conf are not skipped This bug appears as empty entries in the cachemgr.cgi web interface. The Squid CGI tool will now elide such entries from display. * Update systemd dependencies in squid.service The squid.service file published with earlier releases lacked a dependency on networking being fully operational. This resulted in a mix of odd behaviours on machine startup when other networking tools were slow to initialize NIC, DNS, or resolve.conf settings. The squid.service file shipped with this release is expected to wait until all networking resources are operational before Squid is started. All users of Squid-4 are encouraged to upgrade as time permits. All users of Squid-3 are encouraged to upgrade where possible. See the ChangeLog for the full list of changes in this and earlier releases.
