When several "error_log" directives are specified in the same configuration
block, logs are written to all files with a matching log level.
All logs are stored in the singly-linked list that is sorted by log level in
the descending order.
Specific debug levels (NGX_LOG_DEBUG_HTTP,EVENT, etc.) are not supported
if several "error_log" directives are specified. In this case all logs
will use debug level that has largest absolute value.
*) Feature: the "wait" parameter in the "include" SSI command.
*) Feature: the Ukrainian and Byelorussian characters were added to
koi-win conversion table.
*) Bugfix: in the SSI.
*) 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.
*) Bugfix: the arguments were omitted in the redirects, issued by the
"rewrite" directive; the bug had appeared in 0.1.29.
*) Feature: the "if" directive supports the captures in regular
expressions.
*) Feature: the "set" directive supports the variables and the captures
of regular expressions.
*) Feature: the "X-Accel-Redirect" response header line is supported in
proxy and FastCGI mode.
*) Change: the invalid client header lines are now ignored and logged
at the info level.
*) Change: the server name is also logged in error log.
*) Feature: the ngx_http_auth_basic_module module and the auth_basic
and auth_basic_user_file directives.
*) Feature: the ngx_http_ssi_filter_module supports the QUERY_STRING
and DOCUMENT_URI variables.
*) Bugfix: the ngx_http_autoindex_module may some times return the 404
response for existent directory, if this directory was used in
"alias" directive.
*) Bugfix: the ngx_http_ssi_filter_module ran incorrectly for large
responses.
*) Bugfix: the lack of the "Referer" header line was always accounted
as valid referrer.
*) Bugfix: the ngx_http_stub_status_module showed incorrect handled
connections statistics if the proxying or FastCGI server were used.
*) Bugfix: the installation paths were incorrectly quoted on Linux and
Solaris; the bug had appeared in 0.1.21.
*) Bugfix: the ngx_http_stub_status_module showed incorrect statistics
if "rtsig" method was used or if several worker process ran on SMP.
*) Bugfix: nginx could not be built by the icc compiler on Linux or if
the zlib-1.2.x library was building from sources.
*) Bugfix: nginx could not be built on NetBSD 2.0.
*) Bugfix: if the response were transferred by chunks, then on the HEAD
request the final chunk was issued.
*) Bugfix: the "Connection: keep-alive" header were issued, even if the
keepalive_timeout directive forbade the keep-alive use.
*) Bugfix: the errors in the ngx_http_fastcgi_module caused the
segmentation faults.
*) Bugfix: the compressed response encrypted by SSL may not transferred
complete.
*) Bugfix: the TCP-specific TCP_NODELAY, TCP_NOPSUH, and TCP_CORK
options, are not used for the unix domain sockets.
*) Feature: the rewrite directive supports the arguments rewriting.
*) Bugfix: the response code 400 was returned for the POST request with
the "Content-Length: 0" header; the bug had appeared in 0.1.14.
*) 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.
*) Bugfix: the ngx_http_autoindex_module module did not escape the
spaces, the quotes, and the percent signs in the directory listing.
*) Change: the decrease of the copy operations.
*) Feature: the userid_p3p directive.
*) Feature: the --user=USER, --group=GROUP, and --with-ld-opt=OPTIONS
options in configure.
*) Feature: the server_name directive supports *.domain.tld.
*) Bugfix: the portability improvements.
*) Bugfix: if configuration file was set in command line, the
reconfiguration was impossible; the bug had appeared in 0.1.1.
*) Bugfix: proxy module may get caught in an endless loop when sendfile
is not used.
*) Bugfix: with sendfile the response was not recoded according to the
charset module directives; the bug had appeared in 0.1.1.
*) Bugfix: very seldom bug in the kqueue processing.
*) Bugfix: the gzip module compressed the proxied responses that was
already compressed.
