Hi, guys!

I am happy to announce the new development version of ngx_openresty, 1.2.3.1:

http://openresty.org/#Download

Special thanks go to all our contributors and users for making this happen!

Below is the complete change log for this release, as compared to the
last (stable) release, 1.2.1.14:

* upgraded the Nginx core to 1.2.3.

* see http://nginx.org/en/CHANGES-1.2 for changes.

* upgraded LuaNginxModule to 0.6.2.

* feature: (re)implemented the standard Lua coroutine API,
which means that the user is now free to create and run
their own coroutines within the boilerplate coroutine
created automatically by LuaNginxModule. thanks chaoslawful
and jinglong for the design and implementation.

* feature: added new dtrace static probes for the user
coroutine mechanism: "http-lua-coroutine-create" and
"http-lua-coroutine-resume".

* feature: added new dtrace static probes for the cosocket
mechanism: "http-lua-socket-tcp-send-start",
"http-lua-socket-tcp-receive-done", and
"http-lua-socket-tcp-keepalive-buf-unread".

* bugfix: the send timeout timer for downstream output was not
deleted in time in our write event handler, which might
result in request abortion for long running requests. thanks
Demiao Lin (ldmiao) for reporting this issue.

* bugfix: tcpsock:send() might send garbage if it was not the
first call: we did not properly initialize the chain writer
ctx for every "send()" call. thanks Zhu Dejiang for
reporting this issue.

* bugfix: the "ngx_http_lua_probe.h" header file was not
listed in the "NGX_ADDON_DEPS" list in the "config" file.

* optimize: removed unnecessary code that was for the old
coroutine abortion mechanism based on Lua exceptions. we no
longer need that at all because we have switched to using
coroutine yield to abort the current coroutine for
"ngx.exec", "ngx.exit", "ngx.redirect", and
"ngx.req.set_uri(uri, true)".

* upgraded LuaRestyDNSLibrary to 0.06.

* feature: added support for MX type resource records.

* feature: unrecognized types of resource records will return
their raw resource data (RDATA) as the "rdata" Lua table
field.

* upgraded LuaRestyRedisLibrary to 0.13.

* feature: added new method read_reply, mostly for using the
Redis Pub/Sub API.

* feature: added new class method add_commands to allow adding
support for new Redis commands on-the-fly. thanks Praveen
Saxena for requesting this feature.

* docs: added a code sample for using the Redis transactions.

* upgraded DrizzleNginxModule to 0.1.4.

* bugfix: the "open socket #N left in connection" alerts would
appear in the nginx error log file when the MySQL/Drizzle
connection pool was used and the worker process was shutting
down.

* upgraded PostgresNginxModule to 1.0rc2.

* bugfix: the "open socket #N left in connection" alerts would
appear in the nginx error log file when the PostgreSQL
connection pool was used and the worker process was shutting
down.

* bugfix: removed the useless http-cache related code from
"ngx_postgres_upstream_finalize_request" to suppress clang
warnings.

* added more dtrace static probes to the Nginx core: "timer-add",
"timer-del", and "timer-expire".

* added more systemtap tapset functions: "ngx_chain_next",
"ngx_chain_writer_ctx_out", "ngx_chain_dump", and
"ngx_iovec_dump".

OpenResty (aka. ngx_openresty) is a full-fledged web application
server by bundling the standard Nginx core, lots of 3rd-party Nginx
modules, 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!
