nginx 0.8.7 *) 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: the $ssl_client_verify variable. Thanks to Brice Figureau. *) Feature: the "ssl_crl" directive. Thanks to Brice Figureau. *) Feature: the "proxy" parameter of the "geo" directive. *) Feature: the "image_filter" directive supports variables for setting size. *) Bugfix: the $ssl_client_cert variable usage corrupted memory; the bug had appeared in 0.7.7. Thanks to Sergey Zhuravlev. *) 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. *) Bugfix: the "[alert] zero size buf" error if subrequest returns an empty response; the bug had appeared in 0.8.5.
