amd64, sparc, and ppc; the bug had appeared in 0.3.2.

not required a manual rename operation. The old master process adds
the ".oldbin" suffix to its pid-file and executes a new binary file.

suffix. If the master process exits, then old master process renames
back its pid-file with the ".oldbin" suffix to the pid-file without
suffix.

"http_404" parameter of the "proxy_next_upstream" or
"fastcgi_next_upstream" directives was used, then nginx started to
request all backends again.

*) Feature: the "port_in_redirect" directive.
*) Bugfix: the segmentation fault was occurred if the backend response
header was in several packets; the bug had appeared in 0.1.29.
