.. PLEASE keep this roughly in commit order as shown by git-log / tig
(new to old)

+* The ``fold`` flag has been added to Access Control Lists (ACLs)
+ in VCL. When it is activated with ``acl ... +fold {}``, ACL entries
+ get optimized in that subnets contained in other entries are skipped
+ (e.g. if 1.2.3.0/24 is part of the ACL, an entry for 1.2.3.128/25
+ will not be added) and adjacent entries get folded (e.g. if both
+ 1.2.3.0/25 and 1.2.3.128/25 are added, they will be folded to
+ 1.2.3.0/24) (3563_).
+
+ Logging under the ``VCL_acl`` tag can change with this flag.
+
+ Negated ACL entries are never folded.
+
+* Fixed handling of failing sub-requests: A VCL failure on the client
+ side or the ``vcl_req_reset`` feature could trigger a panic, because
+ it is not allowed to generate a minimal response. For sub-requests,
+ we now masquerade the fail transition as a deliver and trade the
+ illegal minimal response for the synthetic response (4022_).
+
+* The ``param.reset [-j]`` CLI command has been added to reset flags
+ to their default. Consequently, the ``param.set ... default``
+ special value is now deprecated.
+
+* The ``param.set`` CLI command now supports the ``none`` and ``all``
+ values to achieve setting "absolute" values atomically as in
+ ``param.set foo none,+bar,+baz`` or ``param.set foo all,-bar,-baz``.
+
+* A glitch in CLI command parsing has been fixed where individually
+ quoted arguments like ``"help"`` were rejected.
+
* The ``vcl_req_reset`` feature (controllable through the ``feature``
parameter, see `varnishd(1)`) has been added and enabled by default
to terminate client side VCL processing early when the client is
