The Squid HTTP Proxy team is very pleased to announce the availability of the Squid-4.0.15 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: This release there are no major changes. Despite the size of code commited most of the change has been small polishing and stability changes. Some incidental and minor memory leaks have been resolved, and some crashes introduced by the new Squid-4 features have been resolved. One change shared with 3.5.22 is noteworthy as it affects cache storage formats: * Bug #4471: revalidation doesn't work when expired cached object lacks Last-Modified header. Historically Squid used only Last-Modified header value for evaluating entry's last modification time while making an internal revalidation requests. So, without Last-Modified it was not possible to correctly fill the If-Modified-Since header value. Which would result in many unnecessary MISS. This release now uses Date header to synthesize a Last-Modified value if none is provided. IMPORTANT: This change affects a binary difference in all cache objects stored by Squid-4.0.15 or later, and by Squid-3.5.22 or later. * When upgrading, older cache content is handled automatically. * When downgrading for any reason to an older version the cache will need to be erased and rebuilt from empty to remove those new objects. 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.
