nginx 0.4.10
*) Feature: the POP3 proxy supports the APOP command.
*) Bugfix: if the select, poll or /dev/poll methods were used, then
while waiting authentication server response the IMAP/POP3 proxy
hogged CPU.
*) Bugfix: a segmentation fault might occur if the $server_addr
variable was used in the "map" directive.
*) Bugfix: the ngx_http_flv_module did not support the byte ranges for
full responses; bug appeared in 0.4.7.
*) Bugfix: nginx could not be built on Debian amd64; bug appeared in
0.4.9.
