Released for production use.
The features have been set and large code changes are reserved for later versions.

The intention with this series is to improve performance and HTTP support. Some remaining Squid-2.7 missing features are listed as regressions in http://www.squid-cache.org/Versions/v3/3.5/RELEASENOTES.html#ss5.1
Packages of what will become squid 3.5 source code are available at http://www.squid-cache.org/Versions/v3/3.5/
See our Advisories list.
- Bugs against any older version can be closed if found fixed in 3.5.
- Bugs inherited from older versions are not necessarily blockers on 3.5 stable.
Squid-3.5 default config
From 3.5 a few performance improvements have been done. The manager regex ACLs have been moved after the DoS and protocol smuggling attack protections.
This minimal configuration does not work with versions earlier than 3.2 which are missing special cleanup done to the code.
