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.
