nginx 0.7.66
*) Security: now nginx/Windows ignores default file stream name.
Thanks to Jose Antonio Vazquez Gonzalez.
*) Change: now the charset filter runs before the SSI filter.
*) Change: now no message is written in an error log if a variable is
not found by $r->variable() method.
*) Change: now keepalive connections after POST requests are not
disabled for MSIE 7.0+.
Thanks to Adam Lounds.
*) Feature: the "proxy_no_cache" and "fastcgi_no_cache" directives.
*) Feature: now the "rewrite" directive does a redirect automatically
if the $scheme variable is used.
Thanks to Piotr Sikora.
*) Feature: the "chunked_transfer_encoding" directive.
*) Feature: the $geoip_city_continent_code, $geoip_latitude, and
$geoip_longitude variables.
Thanks to Arvind Sundararajan.
*) Feature: now the ngx_http_image_filter_module deletes always EXIF
and other application specific data if the data consume more than 5%
of a JPEG file.
*) Feature: now the "msie_padding" directive works for Chrome too.
*) Workaround: now keepalive connections are disabled for Safari.
Thanks to Joshua Sierles.
*) Bugfix: nginx ignored the "private" and "no-store" values in the
"Cache-Control" backend response header line.
*) Bugfix: an "&" character was not escaped when it was copied in
arguments part in a rewrite rule.
*) Bugfix: nginx might be terminated abnormally while a signal
processing or if the directive "timer_resolution" was used on
platforms which do not support kqueue or eventport notification
methods.
Thanks to George Xie and Maxim Dounin.
*) Bugfix: if temporary files and permanent storage area resided at
different file systems, then permanent file modification times were
incorrect.
Thanks to Maxim Dounin.
*) Bugfix: ngx_http_memcached_module might issue the error message
"memcached sent invalid trailer".
Thanks to Maxim Dounin.
*) Bugfix: nginx could not built zlib-1.2.4 library using the library
sources.
Thanks to Maxim Dounin.
*) Bugfix: values of the $query_string, $arg_..., etc. variables cached
in main request were used by the SSI module in subrequests.
*) Bugfix: nginx did not support HTTPS referrers.
*) Bugfix: nginx/Windows might not find file if path in configuration
was given in other character case; the bug had appeared in 0.7.65.
*) Bugfix: the $date_local variable has an incorrect value, if the "%s"
format was used.
Thanks to Maxim Dounin.
*) Bugfix: nginx did not support all ciphers and digests used in client
certificates.
Thanks to Innocenty Enikeew.
*) Bugfix: if ssl_session_cache was not set or was set to "none", then
during client certificate verify the error "session id context
uninitialized" might occur; the bug had appeared in 0.7.1.
*) Bugfix: OpenSSL-1.0.0 compatibility on 64-bit Linux.
Thanks to Maxim Dounin.
*) Bugfix: a geo range returned default value if the range included two
or more /16 networks and did not begin at /16 network boundary.
*) Bugfix: the $uid_got variable might not be used in the SSI and perl
modules.
*) Bugfix: a worker process hung if a FIFO file was requested.
Thanks to Vicente Aguilar and Maxim Dounin.
*) Bugfix: a variable value was repeatedly encoded after each an "echo"
SSI-command output; the bug had appeared in 0.6.14.
*) Bugfix: a "stub" parameter of an "include" SSI directive was not
used, if empty response has 200 status code.
*) Bugfix: a block used in a "stub" parameter of an "include" SSI
directive was output with "text/plain" MIME type.
*) Bugfix: if a proxied or FastCGI request was internally redirected to
another proxied or FastCGI location, then a segmentation fault might
occur in a worker process; the bug had appeared in 0.7.65.
Thanks to Yichun Zhang.
*) Bugfix: IMAP connections may hang until they timed out while talking
to Zimbra server.
Thanks to Alan Batie.
*) Bugfix: nginx did not support chunked transfer encoding for 201
