nginx 1.1.8 *) Change: the ngx_http_limit_zone_module was renamed to the ngx_http_limit_conn_module. *) Change: the "limit_zone" directive was superseded by the "limit_conn_zone" directive with a new syntax. *) Feature: support for multiple "limit_conn" limits on the same level. *) Feature: the "image_filter_sharpen" directive. *) Bugfix: a segmentation fault might occur in a worker process if resolver got a big DNS response. Thanks to Ben Hawkes. *) Bugfix: in cache key calculation if internal MD5 implementation was used; the bug had appeared in 1.0.4. *) Bugfix: the "If-Modified-Since", "If-Range", etc. client request header lines might be passed to backend while caching; or not passed without caching if caching was enabled in another part of the configuration. *) Bugfix: the module ngx_http_mp4_module sent incorrect "Content-Length" response header line if the "start" argument was used. Thanks to Piotr Sikora.
