The REQUEST_SCHEME parameter was introduced in Apache 2.3.11 and seems
to be used by some scripts now. It looks more logical than previously
used HTTPS.
a) ssl as listen parameter is preferable.
b) ssl_protocols defaults are better because they do not forbid TLS versions
1.1 and 1.2.
c) ssl_session_timeout has sense only with SSL cache.
Though there are several MIME types commonly used for JavaScript nowadays,
the most common being "text/javascript", "application/javascript", and
currently used by nginx "application/x-javascript", RFC 4329 prefers
"application/javascript".
The "charset_types" directive's default value was adjusted accordingly.
*) Feature: the "stub" parameter in the "include" SSI command.
*) Feature: the "block" SSI command.
*) Feature: the unicode2nginx script was added to contrib.
*) Bugfix: if a "root" was specified by variable only, then the root
was relative to a server prefix.
*) Bugfix: if the request contained "//" or "/./" and escaped symbols
after them, then the proxied request was sent unescaped.
*) Bugfix: the $r->headers_in("Cookie") of the ngx_http_perl_module now
returns all "Cookie" header lines.
*) Bugfix: a segmentation fault occurred if
"client_body_in_file_only on" was used and nginx switched to a next
upstream.
*) Bugfix: on some condition while reconfiguration character codes
inside the "charset_map" may be treated invalid; the bug had
appeared in 0.3.50.
*) Change: the "proxy_redirect_errors" and "fastcgi_redirect_errors"
directives was renamed to the "proxy_intercept_errors" and
"fastcgi_intercept_errors" directives.
*) Feature: the ngx_http_charset_module supports the recoding from the
single byte encodings to the UTF-8 encoding and back.
*) Feature: the "X-Accel-Charset" response header line is supported in
proxy and FastCGI mode.
*) Bugfix: the "\" escape symbol in the "\"" and "\'" pairs in the SSI
command was removed only if the command also has the "$" symbol.
*) Bugfix: the "<!--" string might be added on some conditions in the
SSI after inclusion.
*) Bugfix: if the "Content-Length: 0" header line was in response, then
in nonbuffered proxying mode the client connection was not closed.
*) Feature: the "proxy_hide_header", "proxy_pass_header",
"fastcgi_hide_header", and "fastcgi_pass_header" directives.
*) Change: the "proxy_pass_x_powered_by", "fastcgi_x_powered_by", and
"proxy_pass_server" directives were canceled.
*) Feature: the "X-Accel-Buffering" response header line is supported
in proxy mode.
*) Bugfix: the reconfiguration bug and memory leaks in the
ngx_http_perl_module.
*) Feature: the "ssl_verify_client", "ssl_verify_depth", and
"ssl_client_certificate" directives.
*) Change: the $request_method variable now returns the main request
method.
*) Change: the ° symbol codes were changed in koi-win conversion
table.
*) Feature: the euro and N symbols were added to koi-win conversion
table.
*) Bugfix: if nginx distributed the requests among several backends and
some backend failed, then requests intended for this backend was
directed to one live backend only instead of being distributed among
the rest.
*) Feature: the "wait" parameter in the "include" SSI command.
*) Feature: the Ukrainian and Byelorussian characters were added to
koi-win conversion table.
*) Bugfix: in the SSI.

"log_format" directive.
*) Feature: the $ssl_protocol and $ssl_cipher variables.
*) Feature: the cache line size detection for widespread CPUs at start
time.

fcntl(2) on platforms different from i386, amd64, sparc64, and ppc.
*) Feature: the "lock_file" directive and the --with-lock-path=PATH
autoconfiguration directive.
*) Bugfix: if the HTTPS protocol was used in the "proxy_pass" directive
then the requests with the body was not transferred.
*) Feature: the "server_names" directive supports the ".domain.tld"
names.
*) Feature: the "server_names" directive uses the hash for the
"*.domain.tld" names and more effective hash for usual names.
*) Change: the "server_names_hash_max_size" and
"server_names_hash_bucket_size" directives.
*) Change: the "server_names_hash" and "server_names_hash_threshold"
directives were canceled.
*) Feature: the "valid_referers" directive uses the hash site names.
*) Change: now the "valid_referers" directive checks the site names
only without the URI part.
*) Bugfix: some ".domain.tld" names incorrectly processed by the
ngx_http_map_module.
*) Bugfix: segmentation fault was occurred if configuration file did
not exist; the bug had appeared in 0.3.12.
*) Bugfix: on 64-bit platforms segmentation fault may occurred on
start; the bug had appeared in 0.3.16.
*) Feature: the ngx_http_map_module.
*) Feature: the "types_hash_max_size" and "types_hash_bucket_size"
directives.
*) Feature: the "ssi_value_length" directive.
*) Feature: the "worker_rlimit_core" directive.
*) Workaround: the connection number in logs was always 1 if nginx was
built by the icc 8.1 or 9.0 compilers with optimization for
Pentium 4.
*) Bugfix: the "config timefmt" SSI command set incorrect time format.
*) Bugfix: nginx did not close connection to IMAP/POP3 backend for the
SSL connections; the bug had appeared in 0.3.13.
Thanks to Rob Mueller.
*) Bugfix: segmentation fault may occurred in at SSL shutdown; the bug
had appeared in 0.3.13.
*) Change: the "valid_referers" directive and the "$invalid_referer"
variable were moved to the new ngx_http_referer_module from the
ngx_http_rewrite_module.
