+
+ <change type="bug" ref="386">
+ <para>Handle If-Modified-Since and ESI sub-objects better,
+ fixing a problem where we sometimes neglected to insert
+ included objects.</para>
+ </change>
+
+ <change type="enh" ref="365">
+ <para><code>restart</code> in <code>vcl_hit</code> is now supported.</para>
+ </change>
+
+ <change type="bug">
+ <para>Setting the TTL of an object to 0 seconds would sometimes
+ cause it to be delivered for up to one second - epsilon. This
+ has been corrected and we should now never deliver those
+ objects to other clients.</para>
+ </change>
+
+ <change type="enh">
+ <para>The malloc storage backend now prints the maximum storage
+ size, just like the file backend.</para>
+ </change>
+
+ <change type="bug" ref="362">
+ <para>Various small documentation bugs have been fixed.</para>
+ </change>
+
+ <change type="bug" >
+ <para>Varnish did not set a default interval for backend
+ probes, causing it to poll the backend continuously. This has
+ been corrected.</para>
+ </change>
+
+ <change type="enh">
+ <para>Allow "true" and "false" when setting boolean parameters,
+ in addition to on/off, enable/disable and yes/no.</para>
+ </change>
+
+ <change type="enh">
+ <para>Default to always talking HTTP 1.1 with the backend.</para>
+ </change>
+
+ <change type="bug" ref="368">
+ <para>Varnish did not make sure the file it was loading was a
+ regular file. This could cause Varnish to crash if it was
+ asked to load a directory or other non-regular file. We now
+ check that the file is a regular file before loading it.</para>
+ </change>
+
+ <change type="enh" ref="210">
+ <para>The binary heap used for expiry processing had
+ scalability problems. Work around this by using stripes of a
+ fixed size, which should make this scale better, particularly
+ when starting up and having lots of objects.</para>
+ </change>
+
+ <change type="bug">
+ <para>When we imported the <code>jemalloc</code> library into
+ the Varnish tree, it did not compile without warnings. This
+ has now been fixed.</para>
+ </change>
+
+ <change type="bug" ref="278">
+ <para>Varnish took a very long time to detect that the backend
+ did not respond. To remedy this, we now have read timeouts in
+ addition to the connect timeout. Both
+ the <code>first_byte_timeout</code> and
+ the <code>between_bytes_timeout</code> defaults to 60 seconds.
+ The connect timeout is no longer in milliseconds, but rather in
+ seconds.</para>
+ </change>
+
+ <change type="enh">
+ <para>Previously, the VCL to C conversion as well as the
+ invocation of the C compiler was done in the management
+ process. This is now done in a separate sub-process. This
+ prevents any bugs in the VCL compiler from affecting the
+ management process.</para>
+ </change>
+
+ <change type="bug">
+ <para>Chunked encoding headers were counted in the statistics
+ for header bytes. They no longer are.</para>
+ </change>
+
+ <change type="bug">
+ <para>ESI processed objects were not counted in the statistics
+ for body bytes. They now are.</para>
+ </change>
+
+ <change type="enh">
+ <para>It is now possible to adjust the maximum record length of
+ log entries in the shmlog by tuning the <code>shm_reclen</code>
+ parameter.</para>
+ </change>
+
+ <change type="enh">
+ <para>The management parameters listed in the CLI were not
+ sorted, which made it hard to find the parameter you were
+ looking for. They are now sorted, which should make this
+ easier.</para>
+ </change>
+
+ <change type="enh">
+ <para>Add a new hashing type, "critbit", which uses a lock-less
+ tree based lookup algorithm. This is experimental and should
+ not be enabled in production environments without proper
+ testing.</para>
+ </change>
+
+ <change type="enh">
+ <para>The session workspace had a default size of 8k. It is
+ now 16k, which should make VCLs where many headers are
+ processed less prone to panics.</para>
+ </change>
+
+ <change type="enh">
+ <para>We have seen that people seem to be confused as to which
+ actions in the different VCL functions return and which ones
+ don't. Add a new syntax <code>return(action)</code> to make
+ this more explicit. The old syntax is still supported.</para>
+ </change>
+
+ <change type="bug" ref="97">
+ <para>Varnish would return an error if any of the management
+ IPs listed in the <code>-T</code> parameter could not be
+ listened to. We now only return an error if none of them can
+ be listened to.</para>
+ </change>
+
+ <change type="bug" ref="416">
+ <para>In the case of the backend or client giving us too many
+ parameters, we used to just ignore the overflowing headers.
+ This is problematic if you end up ignoreing Content-Length,
+ Transfer-Encoding and similar headers. We now give out a 400
+ error to the client if it sends us too many and 503 if we get
+ too many from the backend.</para>
+ </change>
+
+ <change type="bug" ref="387">
+ <para>We used panic if we got a too large chunked header.
+ This behaviour has been changed into just failing the
+ transaction.</para>
+ </change>
+
+ <change type="enh">
+ <para>Varnish now supports an extended purge method where it is
+ possible to do <code>purge req.http.host ~ "web1.com" &amp;&amp; req.url ~ "\.png"
+ </code> and similar. See the documentation for details.</para>
+ </change>
+
+ <change type="bug" ref="418">
+ <para>Under heavy load, Varnish would sometimes crash when
+ trying to update the per-request statistics. This has now been
+ fixed.</para>
+ </change>
+
+ <change type="enh">
+ <para>It is now possible to not save the hash string in the
+ session and object workspace. This will save a lot of memory
+ on sites with many small objects. Disabling
+ the <code>purge_hash</code> parameter also disables
+ the <code>purge.hash</code> facility.</para>
+ </change>
+
+ <change type="enh">
+ <para>Varnish now supports <code>!~</code> as a "no match"
+ regular expression matcher.</para>
+ </change>
+
+ <change type="bug" ref="425">
+ <para>In some cases, you could get serialised access to "pass"
+ objects. We now make it default to the default_ttl value; this
+ can be overridden in vcl_fetch.</para>
+ </change>
+
+ <change type="bug" ref="417">
+ <para>Varnish did not check the syntax of <code>regsub</code>
+ calls properly. More checking has been added.</para>
+ </change>
+
+ <change type="bug" ref="427">
+ <para>If the client closed the connection while Varnish was
+ processing ESI elements, Varnish would crash while trying to
+ write the object to the client. We now check if the client has
+ closed the connection.</para>
+ </change>
+
+ <change type="bug" ref="433">
+ <para>The ESI parser had a bug where it would crash if an XML
+ comment would span storage segments. This has been
+ fixed.</para>
+ </change>
+ </subsystem>
+
+ <subsystem>
+ <name>VCL Manual page</name>
+
+ <change type="bug">
+ <para>The documentation on how capturing parentheses work was
+ wrong. This has been corrected.</para>
+ </change>
+
+ <change type="enh">
+ <para>Grace has now been documented.</para>
+ </change>
+ </subsystem>
+
+ <subsystem>
+ <name>varnishreplay</name>
+
+ <change type="bug">
+ <para><code>varnishreplay</code> did not work correctly on
+ Linux, due to a too small stack. This has now been fixed.</para>
