 * cosocket: implement LuaSocket's unconnected UDP API.
-* port this module to the "datagram" subsystem of NGINX for implementing general UDP servers instead of HTTP
-servers in Lua. For example,
-```lua
-
- datagram {
-     server {
-         listen 1953;
-         handler_by_lua_block {
-             -- custom Lua code implementing the special UDP server...
-         }
-     }
- }
-```
-* shm: implement a "shared queue API" to complement the existing [shared dict](#lua_shared_dict) API.
 * cosocket: add support in the context of [init_by_lua*](#init_by_lua).
 * cosocket: implement the `bind()` method for stream-typed cosockets.
-* cosocket: pool-based backend concurrency level control: implement automatic `connect` queueing when the backend concurrency exceeds its connection pool limit.
 * cosocket: review and merge aviramc's [patch](https://github.com/openresty/lua-nginx-module/pull/290) for adding the `bsdrecv` method.
-* add new API function `ngx.resp.add_header` to emulate the standard `add_header` config directive.
+* cosocket: add configure options for different strategies of handling the cosocket connection exceeding in the pools.
 * review and apply vadim-pavlov's patch for [ngx.location.capture](#ngxlocationcapture)'s `extra_headers` option
 * use `ngx_hash_t` to optimize the built-in header look-up process for [ngx.req.set_header](#ngxreqset_header), [ngx.header.HEADER](#ngxheaderheader), and etc.
-* add configure options for different strategies of handling the cosocket connection exceeding in the pools.
 * add directives to run Lua codes when nginx stops.
 * add `ignore_resp_headers`, `ignore_resp_body`, and `ignore_resp` options to [ngx.location.capture](#ngxlocationcapture) and [ngx.location.capture_multi](#ngxlocationcapture_multi) methods, to allow micro performance tuning on the user side.
 * add automatic Lua code time slicing support by yielding and resuming the Lua VM actively via Lua's debug hooks.
