nginx 1.3.10
*) Change: domain names specified in configuration file are now resolved
to IPv6 addresses as well as IPv4 ones.
*) Change: now if the "include" directive with mask is used on Unix
systems, included files are sorted in alphabetical order.
*) Change: the "add_header" directive adds headers to 201 responses.
*) Feature: the "geo" directive now supports IPv6 addresses in CIDR
notation.
*) Feature: the "flush" and "gzip" parameters of the "access_log"
directive.
*) Feature: variables support in the "auth_basic" directive.
*) Bugfix: nginx could not be built with the ngx_http_perl_module in
some cases.
*) Bugfix: a segmentation fault might occur in a worker process if the
ngx_http_xslt_module was used.
*) Bugfix: nginx could not be built on MacOSX in some cases.
Thanks to Piotr Sikora.
*) Bugfix: the "limit_rate" directive with high rates might result in
truncated responses on 32-bit platforms.
Thanks to Alexey Antropov.
*) Bugfix: a segmentation fault might occur in a worker process if the
"if" directive was used.
Thanks to Piotr Sikora.
*) Bugfix: a "100 Continue" response was issued with "413 Request Entity
Too Large" responses.
*) Bugfix: the "image_filter", "image_filter_jpeg_quality" and
"image_filter_sharpen" directives might be inherited incorrectly.
Thanks to Ian Babrou.
*) Bugfix: "crypt_r() failed" errors might appear if the "auth_basic"
directive was used on Linux.
*) Bugfix: in backup servers handling.
Thanks to Thomas Chen.
*) Bugfix: proxied HEAD requests might return incorrect response if the
"gzip" directive was used.
