nginx 0.7.52
*) Feature: the first native Windows binary release.
*) Bugfix: in processing HEAD method while caching.
*) Bugfix: in processing the "If-Modified-Since", "If-Range", etc.
client request header lines while caching.
*) Bugfix: now the "Set-Cookie" and "P3P" header lines are hidden in
cacheable responses.
*) Bugfix: if nginx was built with the ngx_http_perl_module and with a
perl which supports threads, then during a master process exit the
message "panic: MUTEX_LOCK" might be issued.
*) Bugfix: nginx could not be built --without-http-cache; the bug had
appeared in 0.7.48.
*) Bugfix: nginx could not be built on platforms different from i386,
amd64, sparc, and ppc; the bug had appeared in 0.7.42.
