*) Bugfix: the first "proxy_redirect" directive was working inside one
location.
*) Bugfix: on 64-bit platforms segmentation fault may occurred on start
if the many names were used in the "server_name" directives; the bug
had appeared in 0.3.18.

*) Feature: the "types_hash_max_size" and "types_hash_bucket_size"
directives.
*) Feature: the "ssi_value_length" directive.
*) Feature: the "worker_rlimit_core" directive.

built by the icc 8.1 or 9.0 compilers with optimization for
Pentium 4.

*) Bugfix: nginx did not close connection to IMAP/POP3 backend for the
SSL connections; the bug had appeared in 0.3.13.

variable were moved to the new ngx_http_referer_module from the
ngx_http_rewrite_module.

characters.
*) Bugfix: nginx could not be built by the icc 9.0 compiler.
*) Bugfix: if the SSI was enabled for zero size static file, then the
chunked response was encoded incorrectly.

renamed to the "backlog" and "accept_filter".
*) Feature: the "rcvbuf" and "sndbuf" parameters of the "listen"
directive.
*) Change: the "$msec" log parameter does not require now the
additional the gettimeofday() system call.
*) Feature: the -t switch now tests the "listen" directives.
*) Bugfix: if the invalid address was specified in the "listen"
directive, then after the -HUP signal nginx left an open socket in
the CLOSED state.
*) Bugfix: the mime type may be incorrectly set to default value for
index file with variable in the name; the bug had appeared in 0.3.0.
*) Feature: the "timer_resolution" directive.

*) Bugfix: a temporary file with client request body now is removed
just after the response header was transferred to a client.

*) 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"

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.
*) Feature: the "working_directory" directive.
*) 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.
*) Bugfix: if more than 10 servers were configured or some server did
not use the "listen" directive, then the segmentation fault was
occurred on the start.
*) Bugfix: the segmentation fault might occur if the response was
bigger than the temporary file.
*) Bugfix: nginx returned the 400 response on requests like
"GET http://www.domain.com/uri HTTP/1.0"; the bug had appeared in
0.1.28.
*) Feature: the worker_priority directive.
*) Change: both tcp_nopush and tcp_nodelay directives affect the
transferred response.
*) Bugfix: nginx did not call initgroups().
Thanks to Andrew Sitnikov and Andrei Nigmatulin.

bytes.

broken symlink was in a directory.
*) Bugfix: the files bigger than 4G could not be transferred using
sendfile.
*) Bugfix: if the backend was resolved to several backends and there
was an error while the response waiting then process may got caught
in an endless loop.
*) Bugfix: the worker process may exit with the "unknown cycle" message
when the /dev/poll method was used.
*) Bugfix: "close() channel failed" errors.
*) Bugfix: the autodetection of the "nobody" and "nogroup" groups.
*) Bugfix: the send_lowat directive did not work on Linux.
*) Bugfix: the segmentation fault occurred if there was no events
section in configuration.
*) Bugfix: nginx could not be built on OpenBSD.
*) Bugfix: the double slashes in "://" in the URI were converted to
":/".
*) Bugfix: on Solaris and Linux there may be too many "recvmsg()
returned not enough data" alerts.
*) Bugfix: there were the "writev() failed (22: Invalid argument)"
errors on Solaris in proxy mode without sendfile. On other platforms
that do not support sendfile at all the process got caught in an
endless loop.
*) Bugfix: segmentation fault on Solaris in proxy mode and using
sendfile.
*) Bugfix: segmentation fault on Solaris.
*) Bugfix: on-line upgrade did not work on Linux.
