Squid 5.8 (2023-03-01)

This release is a bug fix release resolving several issues
found in the prior Squid-5 releases.

The major changes to be aware of:

* Bug 5162: mgr:index URL do not produce MGR_INDEX template

This bug shows up as Squid producing just the text "mgr_index" instead
of the intended template contents when the cache manager API is
requested. Breaking the use of third-party cache management tools and
also cachemgr.cgi auto-detection of support for those tools.

* Bug 5241: Block all non-localhost requests by default

This release changes the default squid.conf to disable the rule:

	http_access allow localnet

This change affects new Squid installs only.

* Bug 5241: Block to-localhost, to-link-local requests by default

This release adds a predefined ACL named "to_linklocal" which matches
traffic attempting to access link-local network services. Such traffic
can be a problem for proxy operating within Cloud services or
container hosting.

Squid installations which have enabled:

	http_access deny to_localhost

May wish to also enable:

	http_access deny to_linklocal
