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.
