nginx 1.0.7
*) Change: now if total size of all ranges is greater than source
response size, then nginx disables ranges and returns just the source
response.
*) Feature: the "max_ranges" directive.
*) Feature: the module ngx_http_mp4_module.
*) Feature: the "worker_aio_requests" directive.
*) Bugfix: if nginx was built --with-file-aio it could not be run on
Linux kernel which did not support AIO.
*) Bugfix: in Linux AIO error processing.
Thanks to Hagai Avrahami.
*) Bugfix: in Linux AIO combined with open_file_cache.
*) Bugfix: open_file_cache did not update file info on retest if file
was not atomically changed.
*) Bugfix: reduced memory consumption for long-lived requests.
*) Bugfix: in the "proxy/fastcgi/scgi/uwsgi_ignore_client_abort"
directives.
*) Bugfix: nginx could not be built on MacOSX 10.7.
*) Bugfix: in the "proxy/fastcgi/scgi/uwsgi_ignore_client_abort"
directives.
*) Bugfix: request body might be processed incorrectly if client used
pipelining.
*) Bugfix: in the "request_body_in_single_buf" directive.
*) Bugfix: in "proxy_set_body" and "proxy_pass_request_body" directives
if SSL connection to backend was used.
*) Bugfix: nginx hogged CPU if all servers in an upstream were marked as
"down".
*) Bugfix: a segmentation fault might occur during reconfiguration if
ssl_session_cache was defined but not used in previous configuration.
*) Bugfix: a segmentation fault might occur in a worker process if many
backup servers were used in an upstream.
