*) The pid-file names used during online upgrade was changed and now is
not required a manual rename operation. The old master process adds
the ".oldbin" suffix to its pid-file and executes a new binary file.
The new master process creates usual pid-file without the ".newbin"
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.
*) Change: the "worker_connections" directive, new name of the
"connections" directive; now the directive specifies maximum number
of connections, but not maximum socket descriptor number.
*) Feature: SSL supports the session cache inside one worker process.
*) Feature: the "satisfy_any" directive.
*) Change: the ngx_http_access_module and ngx_http_auth_basic_module do
not run for subrequests.
*) Feature: the "worker_rlimit_nofile" and "worker_rlimit_sigpending"
directives.
*) Bugfix: if all backend using in load-balancing failed after one
error, then nginx did not try do connect to them during 60 seconds.

from the 304 responses.
Thanks to Alexandr Kukushkin.

request contains "//", "/./", "/../" or "%XX".
*) Bugfix: the large compressed responses may be transferred not
completely.
*) Bugfix: the files bigger than 2G was not transferred on Linux that
does not support sendfile64().
*) Bugfix: while the build configuration on Linux the
--with-poll_module parameter was required; the bug had appeared in
0.1.8.
*) Feature: the --user=USER, --group=GROUP, and --with-ld-opt=OPTIONS
options in configure.
*) Feature: the server_name directive supports *.domain.tld.

*) Bugfix: the gzip module compressed the proxied responses that was
already compressed.
*) Feature: the gzip_types directive.
*) Feature: the tcp_nodelay directive.
