nginx-0.2.0-RELEASE import
*) 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.
*) Bugfix: in IMAP/POP3 command argument parsing.
Thanks to Rob Mueller.
*) Bugfix: errors while using SSL in IMAP/POP3 proxy.
*) Bugfix: errors while using SSI and gzipping.
*) Bugfix: the "Expires" and "Cache-Control" header lines were omitted
from the 304 responses.
Thanks to Alexandr Kukushkin.
