🔗 Squid-2.7

today Squid-2.x is CONSIDERED DANGEROUS as the security people say. Due to unfixed vulnerabilities CVE-2014-7141, CVE-2014-7142, CVE-2014-6270, CVE-2012-5643, CVE-2013-0189, CVE-2009-0801 and any other recently discovered issues.
Aug 2012 the Squid-2.7 series became OBSOLETE with the release of Squid-3.2 features
Aug 2011 Henrik announced end of Squid-2.x support and DEPRECATED Squid-2.7

This is the last Squid-2 “stable” release. No new features are planned at this time for inclusion into Squid-2.7.

During 2006 and 2007 AdrianChadd continued to develop the Squid-2 branch post- Squid-2.6 to meet performance, scalability and functionality demands in high-performance environments. Additional patches and features continued to be provided by interested users as well.

Unfortunately most of them were not ported to Squid-3.0 which compounded the problem begun with Squid-2.6. These features developed specifically for high-performance needs were found to be large enough to gather for an additional Squid-2.7 release in parallel with the maturing Squid-3.0.

🔗 The Future

With two Squid releases now provided and supported. The core developers gathered to discuss what alternatives could be taken other than further splitting the code between two branches.

However AdrianChadd had further plans for Squid-2 and Squid-3.0 was clearly not meeting the needs of some major users. The goalposts had shifted, as the saying goes. With a 5:1 split of developers working on Squid-3 over Squid-2 the feature parity gap was closing, but not fast enough to prevent confusion amongst the users.

The future aims of the project developers is to provide a single release with all the features needed by each user group. The RoadMap/Squid3 page describes our future plans in more detail than are relevant here.

🔗 Split Choice

As it stands, users will still need to make a choice between Squid-3.0 and Squid-2.7 when moving away from Squid-2.5 and Squid-2.6. This decision needs to be made on the basis of their feature needs.

The only help we can provide for this is to point out that:
