<br>
*) Change: cache header format has been changed, previously cached<br>
responses will be invalidated.<br>
<br>
*) Feature: support of "stale-while-revalidate" and "stale-if-error"<br>
extensions in the "Cache-Control" backend response header line.<br>
<br>
*) Feature: the "proxy_cache_background_<wbr>update",<br>
"fastcgi_cache_background_<wbr>update", "scgi_cache_background_update"<wbr>,<br>
and "uwsgi_cache_background_<wbr>update" directives.<br>
<br>
*) Feature: nginx is now able to cache responses with the "Vary" header<br>

versions).<br>
<br>
*) Feature: the "build" parameter of the "server_tokens" directive.<br>
Thanks to Tom Thorogood.<br>
<br>

when handling requests with the "Expect: 100-continue" request header<br>
line.<br>
<br>

<br>
*) Bugfix: a segmentation fault might occur in a worker process when<br>
using AIO after an "X-Accel-Redirect" redirection.<br>
