<subsystem>
<name>varnishd</name>
<change type="bug">
<para>Only look for sendfile on platforms where we know how to
use it, which is FreeBSD for now.</para>
</change>
<change type="bug">
<para>Make it possible to adjust the shared memory log size and
bump the size from 8MB to 80MB.</para>
</change>
<change type="enh">
<para>Fix up the handling of request bodies to better match
what RFC2616 mandates. This makes PUT, DELETE, OPTIONS and
TRACE work in addition to POST. </para>
</change>
<change type="enh">
<para>Change how backends are defined, to a constant structural
defintion style. See
http://varnish.projects.linpro.no/wiki/VclSyntaxChanges for the
details.</para>
</change>
<change type="enh">
<para>Add directors, which wrap backends. Currently, there's a
random director and a round-robin director.</para>
</change>
<change type="enh">
<para>Add "grace", which is for how long and object will be
served, even after it has expired. To use this, both the
object's and the request's <code>grace</code> parameter need
to be set.</para>
</change>
<change type="enh">
<para>Manual pages have been updated for new VCL syntax and
varnishd options.</para>
</change>
<change type="enh">
<para>Man pages and other docs have been updated.</para>
</change>
<change type="enh">
<para>The shared memory log file is now locked in memory, so it
should not be paged out to disk.</para>
</change>
<change type="enh">
<para>We now handle Vary correctly, as well as Expect.</para>
</change>
<change type="enh">
<para>ESI include support is implemented.</para>
</change>
<change type="enh">
<para>Make it possible to limit how much memory the malloc uses.</para>
</change>
<change type="enh">
<para>Solaris is now supported.</para>
</change>
<change type="enh">
<para>There is now a <code>regsuball</code> function, which
works like <code>regsub</code> except it replaces all
occurences of the regex, not just the first.</para>
</change>
<change type="enh">
<para>Backend and director declarations can have
a <code>.connect_timeout</code> parameter, which tells us how
long to wait for a successful connection.</para>
</change>
<change type="enh">
<para>It is now possible to select the acceptor to use by
changing the <code>acceptor</code> parameter.</para>
</change>
<change type="enh">
<para>Backends can have probes associated with them, which can
be checked with <code>req.backend.health</code> in VCL as well as
being handled by directors which do load-balancing.</para>
</change>
<change type="enh">
<para>Support larger-than-2GB files also on 32 bit hosts.
Please note that this does not mean we can support caches
bigger than 2GB, it just means logfiles and similar can be
bigger.</para>
</change>
<change type="bug">
<para>In some cases, we would remove the wrong header when we
were stripping Content-Transfer-Encoding headers from a
request. This has been fixed.</para>
</change>
<change type="enh">
<para>Backends can have a <code>.max_connections</code>
associated with them.</para>
</change>
<change type="bug">
<para>On Linux, we need to set the dumpable bit on the child if
we want core dumps. Make sure it's set.</para>
</change>
<change type="bug">
<para>Doing <code>purge.hash()</code> with an empty string
would cause us to dump core. Fixed so we don't do that any
more.</para>
</change>
<change type="bug">
<para>We ran into a problem with glibc's malloc on Linux where
it seemed like it failed to ever give memory back to the OS,
causing the system to swap. We have now switched to jemalloc
which appears not to have this problem.</para>
</change>
<change type="bug">
<para><code>max_restarts</code> was never checked, so we always
ended up running out of workspace. Now, <code>vcl_error</code>
is called when we reach <code>max_restarts</code>.</para>
</change>
</subsystem>
<subsystem>
<name>varnishtest</name>
<change type="enh">
<para><code>varnishtest</code> is a tool to do correctness tests
of varnishd. The test suite is run by using <code>make
check</code>.</para>

write. This makes <code>tail -f</code> work correctly, as well
as avoiding broken lines in the log file.</para>
</change>
<change type="enh">
<para>It is possible to get <code>varnishncsa</code> to output
the <code>X-Forwarded-For</code> instead of the client IP by
passing <code>-f</code> to it.</para>

</subsystem>
<subsystem>
<name>Build system</name>
<change type="bug">
<para>Various sanity checks have been added
to <code>configure</code>, it now complains about no ncurses or

aborts if there's no working acceptor mechanism </para>

when running configure.</para>
