The ngx_thread_write_chain_to_file() function introduced, which
uses ngx_file_t thread_handler, thread_ctx and thread_task fields.
The task context structure (ngx_thread_file_ctx_t) is the same for
both reading and writing, and can be safely shared as long as
operations are serialized.
The task->handler field is now always set (and not only when task is
allocated), as the same task can be used with different handlers.
The thread_write flag is introduced in the ngx_temp_file_t structure
to explicitly enable use of ngx_thread_write_chain_to_file() in
ngx_write_chain_to_temp_file() when supported by caller.
In collaboration with Valentin Bartenev.
This simplifies the interface of the ngx_thread_read() function.
Additionally, most of the thread operations now explicitly set
file->thread_task, file->thread_handler and file->thread_ctx,
to facilitate use of thread operations in other places.
(Potential problems remain with sendfile in threads though - it uses
file->thread_handler as set in ngx_output_chain(), and it should not
be overwritten to an incompatible one.)
In collaboration with Valentin Bartenev.
The use_temp_path http cache feature is now implemented using a separate temp
hierarchy in cache directory. Prefix-based temp files are no longer needed.
If a relative path is set by variables, then the ngx_conf_full_name()
function was called while processing requests, which causes allocations
from the cycle pool.
A new function that takes pool as an argument was introduced.
and introduce "client_body_in_file_only clean"
introduce ngx_pool_delete_file() to not break a possible third-party
ngx_pool_cleanup_file() usage that may lead to an removal of the useful files
delete unnecessary ngx_http_finalize_request_body()
*) Feature: the "dav_access" directive.
*) Feature: the "if" directive supports the "-d", "!-d", "-e", "!-e",
"-x", and "!-x" operators.
*) Bugfix: a segmentation fault occurred if a request returned a
redirect and some sent to client header lines were logged in the
access log.
*) Feature: the ngx_http_dav_module supports the MKCOL method.
*) Feature: the "create_full_put_path" directive.
*) Feature: the "$limit_rate" variable.

Thanks to Sergey Skvortsov.
*) Feature: the ngx_http_perl_module supports the $r->request_body_file
method.
*) Feature: the "client_body_in_file_only" directive.
*) Workaround: now on disk overflow nginx tries to write access logs
once a second only.
Thanks to Anton Yuzhaninov and Maxim Dounin.
*) Bugfix: now the "limit_rate" directive more precisely limits rate if
rate is more than 100 Kbyte/s.
Thanks to ForJest.
*) Bugfix: now the IMAP/POP3 proxy escapes the "\r" and "\n" symbols in
login and password to pass authorization server.
Thanks to Maxim Dounin.
*) Feature: the Sun Studio 10 C compiler support.
*) Feature: the "proxy_upstream_max_fails",
"proxy_upstream_fail_timeout", "fastcgi_upstream_max_fails", and
"fastcgi_upstream_fail_timeout" directives.
*) Bugfix: nginx could not be built with the --without-pcre parameter;
the bug had appeared in 0.1.29.
*) Bugfix: 3, 4, 7, and 8 the "proxy_set_header" directives in one
level cause the bus fault on start up.
*) Bugfix: the HTTP protocol was specified in the HTTPS redirects.
*) Bugfix: if the "rewrite" directive used the captures inside the "if"
directive, then the 500 error code was returned.
*) Bugfix: nginx did run on Linux parisc.
*) Feature: nginx now does not start under FreeBSD if the sysctl
kern.ipc.somaxconn value is too big.
*) Bugfix: if a request was internally redirected by the
ngx_http_index_module module to the ngx_http_proxy_module or
ngx_http_fastcgi_module modules, then the index file was not closed
after request completion.
*) Feature: the "proxy_pass" can be used in location with regular
expression.
*) Feature: the ngx_http_rewrite_filter_module module supports the
condition like "if ($HTTP_USER_AGENT ~ MSIE)".
*) Bugfix: nginx started too slow if the large number of addresses and
text values were used in the "geo" directive.

will be removed soon.

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.
*) Feature: the autoconfiguration directives:
--http-client-body-temp-path=PATH, --http-proxy-temp-path=PATH, and
--http-fastcgi-temp-path=PATH
*) Change: the directory name for the temporary files with the client
request body is specified by directive client_body_temp_path, by
default it is <prefix>/client_body_temp.
*) Feature: the ngx_http_fastcgi_module and the directives:
fastcgi_pass, fastcgi_root, fastcgi_index, fastcgi_params,
fastcgi_connect_timeout, fastcgi_send_timeout, fastcgi_read_timeout,
fastcgi_send_lowat, fastcgi_header_buffer_size, fastcgi_buffers,
