nginx 0.7.63
*) Security: now "/../" are disabled in "Destination" request header
line.
*) Change: minimum supported OpenSSL version is 0.9.7.
*) Change: the "ask" parameter of the "ssl_verify_client" directive was
changed to the "optional" parameter and now it checks a client
certificate if it was offered.
Thanks to Brice Figureau.
*) Feature: now the "-V" switch shows TLS SNI support.
*) Feature: the $ssl_client_verify variable.
Thanks to Brice Figureau.
*) Feature: the "ssl_crl" directive.
Thanks to Brice Figureau.
*) Bugfix: the $ssl_client_cert variable usage corrupted memory; the
bug had appeared in 0.7.7.
Thanks to Sergey Zhuravlev.
*) Feature: now the start cache loader runs in a separate process; this
should improve large caches handling.
*) Feature: now temporary files and permanent storage area may reside
at different file systems.
*) Bugfix: nginx counted incorrectly disk cache size.
*) Change: now directive "gzip_disable msie6" does not disable gzipping
for MSIE 6.0 SV1.
*) Bugfix: nginx always added "Vary: Accept-Encoding" response header
line, if both "gzip_static" and "gzip_vary" were on.
*) Feature: the "proxy" parameter of the "geo" directive.
*) Feature: the ngx_http_geoip_module.
*) Feature: the "limit_rate_after" directive.
Thanks to Ivan Debnar.
*) Feature: the "limit_req_log_level" and "limit_conn_log_level"
directives.
*) Bugfix: now "limit_req" directive conforms to the leaky bucket
algorithm.
Thanks to Maxim Dounin.
*) Bugfix: in ngx_http_limit_req_module.
Thanks to Maxim Dounin.
*) Bugfix: now nginx allows underscores in a request method.
*) Bugfix: "proxy_pass_header" and "fastcgi_pass_header" directives did
not pass to a client the "X-Accel-Redirect", "X-Accel-Limit-Rate",
"X-Accel-Buffering", and "X-Accel-Charset" lines from backend
response header.
Thanks to Maxim Dounin.
*) Bugfix: in handling "Last-Modified" and "Accept-Ranges" backend
response header lines; the bug had appeared in 0.7.44.
Thanks to Maxim Dounin.
*) Feature: the "image_filter_transparency" directive.
*) Feature: the "image_filter" directive supports variables for setting
size.
*) Bugfix: in PNG alpha-channel support in the
ngx_http_image_filter_module.
*) Bugfix: in transparency support in the ngx_http_image_filter_module.
*) Feature: now several "perl_modules" directives may be used.
*) Bugfix: ngx_http_perl_module responses did not work in subrequests.
*) Bugfix: nginx sent '\0' in a "Location" response header line on
MKCOL request.
Thanks to Xie Zhenye.
*) Bugfix: an "error_page" directive did not redirect a 413 error; the
bug had appeared in 0.6.10.
*) Bugfix: in memory allocation error handling.
Thanks to Maxim Dounin and Kirill A. Korinskiy.
