[Yichun Zhang (agentzh)]

Hello folks!

I am happy to announce that the new development version of
ngx_openresty, 1.4.1.3, is now released:

    http://openresty.org/#Download

Special thanks go to all our contributors and users for helping make
this release happen!

Below is the complete change log for this release, as compared to the
last (devel) release, 1.4.1.1:

 *   upgraded LuaNginxModule to 0.8.6.

     *   feature: added new method get_stale to shared dict objects,
         which returns the value (if not freed yet) even if the key
         has already expired. thanks Matthieu Tourne for the patch.

     *   bugfix: segfaults would happen in ngx.req.set_header() and
         ngx.req.clear_header() for HTTP 0.9 requests. thanks Bin
         Wang for the report.

     *   bugfix: segfault might happen when reading or writing to a
         response header via the ngx.header.HEADER API in the case
         that the nginx core initiated a 301 (auto) redirect. this
         issue was caused by an optimization in the Nginx core where
         "ngx_http_core_find_config_phase", for example, does not
         fully initialize the "Location" response header after
         creating the header. thanks Vladimir Protasov for the
         report.

     *   bugfix: memory leak would happen when using the ngx.ctx API
         before another Nginx module (other than LuaNginxModule)
         initiates an internal redirect.

     *   bugfix: use of the ngx.ctx table in the context of ngx.timer
         callbacks would leak memory.

     *   bugfix: the "connect() failed" error message was still
         logged even when lua_socket_log_errors was off. thanks Dong
         Fang Fan for the report.

     *   bugfix: we incorrectly returned the 500 error code in our
         output header filter, body filter, and log-phase handlers
         upon Lua code loading errors.

     *   bugfix: Lua stack overflow might happen when we failed to
         load Lua code from the code cache.

     *   bugfix: the error message was misleading when the
         *_by_lua_file config directives failed to load the Lua file
         specified.

     *   bugfix: give the argument of 'void' to function definitions
         which has no arguments. thanks Tatsuhiko Kubo for the patch.

     *   bugfix: when our "at-panic" handler for Lua VM gets called,
         the Lua VM is not recoverable for future use. so now we try
         to quit the current Nginx worker gracefully so that the
         Nginx master can spawn a new one.

 *   upgraded HeadersMoreNginxModule to 0.22.

     *   bugfix: segfaults would happen in more_set_input_headers and
         more_clear_input_headers when processing HTTP 0.9 requests.
         thanks Bin Wang for the patch.

     *   bugfix: segfault might happen when using more_set_headers or
         more_clear_headers in the case that the Nginx core initiated
         a 301 (auto) redirect. this issue was caused by an
         optimization in the Nginx core where
         "ngx_http_core_find_config_phase", for example, does not
         fully initialize the "Location" response header after
         creating the header. thanks Brian Akins for the report.

 *   upgraded SrcacheNginxModule to 0.22.

     *   bugfix: we did not always read the client request body
         before initiating srcache_fetch subrequests at the "access
         phase", which could lead to bad consequences.

 *   upgraded EchoNginxModule to 0.46.

     *   bugfix: the request body was not discarded properly in the
         content handler when the request body was not read yet.
         thanks Peter Sabaini for the report.

     *   bugfix: we did not ensure that the main request body is
         always read before subrequests are initiated, which could
         lead to bad consequences.

     *   bugfix: $echo_client_request_headers may evaluate to an
         empty value when the default header buffer ("c->buffer") can
         hold the request line but not the whole header. thanks KDr2
         for reporting this issue.

     *   docs: fixed a typo in Synopsis reported by saighost.

     *   docs: use https for github links. thanks Olivier Mengué for
         the patch.

 *   upgraded PostgresNginxModule to 1.0rc3.

     *   bugfix: compilation error happened with nginx 1.5.3+ because
         the Nginx core changes the "ngx_sock_ntop" API. thanks
         an0ma1ia for the report.

OpenResty (aka. ngx_openresty) is a full-fledged web application
server by bundling the standard Nginx core, lots of 3rd-party Nginx
modules and Lua libraries, as well as most of their external
dependencies. See OpenResty's homepage for details:

    http://openresty.org/

We have been running extensive testing on our Amazon EC2 test cluster
and ensure that all the components (including the Nginx core) play
well together. The latest test report can always be found here:

Enjoy!
