annotate src/core/ngx_crc32.h @ 496:116d5de7cbb6 NGINX_0_7_60
nginx 0.7.60
*) Feature: the "updating" parameter in "proxy_cache_use_stale" and
"fastcgi_cache_use_stale" directives.
*) Feature: the "keepalive_requests" directive.
*) Bugfix: in open_file_cache and proxy/fastcgi cache interaction on
start up.
*) Bugfix: open_file_cache might cache open file descriptors too long.
*) Bugfix: the "If-Modified-Since", "If-Range", etc. client request
header lines were passed to backend while caching if no
"proxy_set_header" directive was used with any parameters.
*) Bugfix: the "Set-Cookie" and "P3P" response header lines were not
hidden while caching if no "proxy_hide_header/fastcgi_hide_header"
directives were used with any parameters.
*) Bugfix: the ngx_http_image_filter_module did not support GIF87a
format.
Thanks to Denis Ilyinyh.
*) Bugfix: nginx could not be built modules on Solaris 10 and early;
the bug had appeared in 0.7.56.
*) Bugfix: XLST filter did not work in subrequests.
*) Bugfix: in relative paths handling in nginx/Windows.
*) Bugfix: in proxy_store, fastcgi_store, proxy_cache, and
fastcgi_cache in nginx/Windows.
