nginx 0.6.14
*) Change: now by default the "echo" SSI command uses entity encoding.
*) Feature: the "encoding" parameter in the "echo" SSI command.
*) Feature: the "access_log" directive may be used inside the
"limit_except" block.
*) Bugfix: if all upstream servers were failed, then all servers had
got weight the was equal one until servers became alive; bug
appeared in 0.6.6.
*) Bugfix: a segmentation fault occurred in worker process if
$date_local and $date_gmt were used outside the
ngx_http_ssi_filter_module.
*) Bugfix: a segmentation fault might occur in worker process if debug
log was enabled.
Thanks to Andrei Nigmatulin.
*) Bugfix: ngx_http_memcached_module did not set
$upstream_response_time.
Thanks to Maxim Dounin.
*) Bugfix: a worker process may got caught in an endless loop, if the
memcached was used.
*) Bugfix: nginx supported low case only "close" and "keep-alive"
values in the "Connection" request header line; bug appeared in
