nginx 1.0.12
*) Feature: the "TLSv1.1" and "TLSv1.2" parameters of the
"ssl_protocols" directive.
*) Feature: the "if" SSI command supports captures in regular
expressions.
*) Bugfix: the "if" SSI command did not work inside the "block" command.
*) Bugfix: in AIO error handling on FreeBSD.
*) Bugfix: in the OpenSSL library initialization.
*) Bugfix: the "worker_cpu_affinity" directive might not work.
*) Bugfix: the "limit_conn_log_level" and "limit_req_log_level"
directives might not work.
*) Bugfix: the "read_ahead" directive might not work combined with
"try_files" and "open_file_cache".
*) Bugfix: the "proxy_cache_use_stale" directive with "error" parameter
did not return answer from cache if there were no live upstreams.
*) Bugfix: a segmentation fault might occur in a worker process if small
time was used in the "inactive" parameter of the "proxy_cache_path"
directive.
*) Bugfix: responses from cache might hang.
*) Bugfix: in error handling while connecting to a backend.
Thanks to Piotr Sikora.
*) Bugfix: in the "epoll" event method.
Thanks to Yichun Zhang.
*) Bugfix: the $sent_http_cache_control variable might contain a wrong
value if the "expires" directive was used.
Thanks to Yichun Zhang.
*) Bugfix: the "limit_rate" directive did not allow to use full
throughput, even if limit value was very high.
*) Bugfix: the "sendfile_max_chunk" directive did not work, if the
"limit_rate" directive was used.
*) Bugfix: nginx could not be built on Solaris; the bug had appeared in
1.0.11.
*) Bugfix: in the ngx_http_scgi_module.
*) Bugfix: in the ngx_http_mp4_module.
