All releases of Squid
Release Notes: This release brings a long list of bug fixes and some further HTTP/1.1 improvements. Some small but cumulative memory leaks were found and fixed in Digest authentication and adaptation ACL processing. New limits are placed on memory consumption when uploading files and when using delay pools. Users of Squid-3 experiencing memory or large cache problems are urged to upgrade as soon as possible.
Release Notes: Several small memory leaks have been found and fixed in the Netdb, DNS, ICAP, ICY, and HTTPS protocol handling. The leaks are very small but accumulate per request. Production sites with a lot of traffic and/or long proxy uptimes may find an upgrade to this release helps with long-term memory usage. Several crashes during helper failure recovery, ICAP failure recovery, and the old DNS server have been resolved. Several Solaris problems are resolved, with the most notable being /dev/poll support ported from 2.7.
Release Notes: A new version numbering system was added. Minimal squid.conf improvements were made. Native IPv6 support was added. Error pages have been localized. Connection pinning was implemented (for NTLM auth passthrough). Quality of service (QoS) flow support was added. SSL bump was added (for HTTPS filtering and adaptation). eCAP adaptation module support was added. ICAP bypass and retry enhancements were made. ICY streaming protocol support was added.
Release Notes: This release only has portability fixes. No change in functionality was made. An OpenSSL related compilation issue introduced in 2.7.STABLE8 was fixed. A problem was fixed in which configure failed to detect certain system libraries on some systems, resulting in compilation failures either in Squid or helpers.
Release Notes: A hang with 100% CPU usage would occur if using external_acl_type or access_log format. wbinfo_group.pl produced false positives under certain conditions. The documentation was corrected. And many other minor bugs were fixed.
Release Notes: Squid-3 is the next generation Squid HTTP proxy largely rewritten in C++. This release features, along with many other small things, an ICAP client that can be used to integrate virus scanners and other content inspection or modification tasks.
Release Notes: Basic HTTP/1.1 support. Many other small additions.
Release Notes:
Release Notes: A wccp2_weight directive was added. Numeros COSS fixes and improvements were done. WCCP2 hash based assignment and weighted assignments are supported. Many small fixes were made to better detect invalid configurations. An FTP related memory leak was fixed. SNMP mib updates were done for some minor missing details. Those harmless ETag loop warnings have been silenced. Squid no longer crashes on certain malformed HTTP responses. A number of other minor and cosmetic bugfixes were made.
Release Notes: Performance was increased with kqueue/epoll support. The reverse proxy setup was simplified and improved. Transparent interception setup was simplified. WCCPv2 support was added. Vary/ETag based caching was added to improve caching of negotiatiated content. Access logs are customizable. "Negotiate" authentication scheme support has been added. Linux TPROXY is supported. Support for proxying of Microsoft Integrated Login sessions was added. X-Forwarded-For headers are optionally followed for flexible access controls in cache hierarchies. A lot more was done.
