nginx 0.5.13
*) Feature: the COPY and MOVE methods.
*) Bugfix: the ngx_http_realip_module set garbage for requests passed
via keep-alive connection.
*) Bugfix: nginx did not work on big-endian 64-bit Linux.
Thanks to Andrei Nigmatulin.
*) Bugfix: now when IMAP/POP3 proxy receives too long command it closes
the connection right away, but not after timeout.
*) Bugfix: if the "epoll" method was used and a client closed a
connection prematurely, then nginx closed the connection after a
send timeout only.
*) Bugfix: nginx could not be built on platforms different from i386,
amd64, sparc and ppc; bug appeared in 0.5.8.
