+This prerelease introduces support for Proxy-Wasm metrics and fixes a number of
+issues related to the execution of Proxy-Wasm dispatches and Lua bridge threads
+(`proxy_wasm_lua_resolver` directive).
+
+#### Changes
+
+> [0.3.0...0.4.0](https://github.com/Kong/ngx_wasm_module/compare/prerelease-0.3.0...prerelease-0.4.0)
+
+- Proxy-Wasm
+    - Feature: implement support for Proxy-Wasm ABI v0.2.1 metrics.
+    - Feature: allow setting the `:status` pseudo-header on response for status
+      manipulation.
+    - Bugfix: cancel dispatches when immediately producing a response before a
+      scheduled dispatch starts.
+    - Misc: consistent context checks for all request/response header setters.
+    - Misc: dispatch errors do not interrupt filter chains anymore.
+- Wasmtime
+    - Feature: new `cache_config` directive to enable compilation cache.
+- V8
+    - Bugfix: prevent a segfault loading an empty `.wat` module with V8.
+- LuaJIT FFI
+    - Bugfix: allow `proxy_wasm.load()` to fail and be invoked again.
+- Lua bridge
+    - Bugfix: properly support multiple parallel yielding Lua threads (e.g.
+      `proxy_wasm_lua_resolver` directive).
+- Misc
+    - Feature: new `postpone_rewrite` and `postpone_access` directives.
+    - Bugfix: resume content phase when reading request body produced EAGAIN.
+    - Bugfix: fix memory reallocation when a key/value pair has its value replaced
+      by a larger one.
+
