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 0.6.11. *) Bugfix: sub_filter did not work with empty substitution. *) Bugfix: in sub_filter parsing.
