1.0.0 candidate of our extension with storage engines (stevedores) and
storage routers (loadmasters).</p>
<p>Over the past year, we have received a lot of helpful input from our
users and have implemented substantial improvements. THANK YOU to
everyone who has contributed by reporting issues, providing feedback
and, just recently, adding documentation. SLASH/fellow has also helped
improve Varnish-Cache itself.</p>
<p>After rigorous testing in particular over the past weeks, we now
boldly claim that SLASH/ deserves a 1.0 version tag.</p>
<p>HAPPY BIRTHDAY Varnish-Cache!</p>

<h3>2020-09-25 - Varnish 6.5.1 is released<a class="headerlink" href="#varnish-6-5-1-is-released" title="Permalink to this heading">¶</a></h3>
<p>When preparing the 6.5.0 release, it was forgotten to bump the
VRT_MAJOR_VERSION number defined in the <cite>vrt.h</cite> include file. This major
version bump is needed due to the API and ABI changes as part of the
release, to make sure that VMODs are not allowed used if they were
compiled for the wrong Varnish version.</p>
<p>This has been fixed in the <a class="reference internal" href="releases/rel6.5.1.html#rel6-5-1"><span class="std std-ref">Varnish Cache 6.5.1</span></a> release.</p>
