The Squid HTTP Proxy team is very pleased to announce the availability of the Squid-4.0.16 release! This release is a bug fix and stability release resolving several issues found in the prior Squid releases. The major changes to be aware of: * Regex ACL performance improvement The code loading regex ACL data has been refactored. The result has been a surprisingly large improvement in speed when loading configuration files containing regex ACLs with many values. * HTTP: initial support for Cache-Control:immutable The 'immutable' Cache-Control value is a new experimental caching control which allows servers to indicate certain responses are not going to change during their freshness lifetime. It is an improved version the refresh_pattern 'ignore-reload' option. NP: the 'ignore-reload' option remains until this control is fully standardised. It is expected to become increasingly useless as wider use of 'immutable' grows amongst servers. Some changes shared with the future 3.5.23 release are noteworthy: * Bug #4627: fix generate-host-certificates default The squid.conf documentation has for some time said that this feature was enabled by default. That was incorrect for Squid-3 and previous Squid-4 releases. This release actually enables the certificate generator by default in Squid-4. * HTTP: support Vary:* caching Under RFC 2616 responses containing "Vary: *" header were not cachable. That requirement has been loosened by RFC 7231 and Squid is now able to cache these responses. * ssl::server_name ACL badly broken since inception The original server_name code mishandled all SNI checks and some rare host checks. This was most visible with the reports that the ssl::server_name ACL tests would fail where the equivalent regex ACL test would behave differently, usually by matching. Or in situations where neither would match despite the value appearing to be available. All users of Squid-4.0.x with ACL type ssl::server_name or ssl::server_name_regex should upgrade to this release and re-test for desired SSL-Bump feature behaviour. All users of Squid-4.0.x are encouraged to upgrade to this release as soon as possible. All users of Squid-3 are encouraged to test this release out and plan for upgrades where possible. See the ChangeLog for the full list of changes in this and earlier releases.
