Added the function :ref:`vmod_directors.lookup`, only for use in
``vcl_init`` or ``vcl_fini``.
varnishlog(1) and vsl(7)
========================
Timing information is now uniformly reported with microsecond
precision. This affects the tags ``ExpKill`` and ``ExpRearm``
(previously with nanosecond precision).
varnishlog(1), varnishncsa(1) and vsl(7)
========================================
The performance of bundled log readers, including ``varnishlog`` and
``varnishncsa`` (and any tool using the internal VUT interface for
Varnish utilities) has been improved. They continue reading log
contents in bulk as long as more contents are known to be available,
not stopping as frequently (and unnecessarily) to check the status of
the shared memory mapping.
``varnishlog`` and ``varnishncsa`` now have the ``-R`` command-line
option for rate-limiting, to limit the number of log transactions read
per unit time. This can make it less likely for log reads to fall
behind and fail with overrun errors under heavy loads. See
:ref:`varnishlog(1)` and :ref:`varnishncsa(1)` for details.
Timing information is now uniformly reported in the log with
microsecond precision. This affects the tags ``ExpKill`` and
``ExpRearm`` (previously with nanosecond precision).
