 ### Added
 
+* Cranelift's has initial support for inlining between functions. Wasmtime
+  additionally now has support for inlining as well, for example between modules
+  in a component.
+  [#11210](https://github.com/bytecodealliance/wasmtime/pull/11210)
+  [#11239](https://github.com/bytecodealliance/wasmtime/pull/11239)
+  [#11228](https://github.com/bytecodealliance/wasmtime/pull/11228)
+  [#11269](https://github.com/bytecodealliance/wasmtime/pull/11269)
+  [#11283](https://github.com/bytecodealliance/wasmtime/pull/11283)
+
+* The async proposal for the Component Model is now fully implemented in
+  Wasmtime with a number of WASIp3 interfaces implemented. The implementation
+  is still off-by-default and the implementation of WASIp3 is not fully
+  complete, but is remains suitable for testing.

 ### Changed
 
-Users who implemented `WasiHttpView::is_forbidden_header` from `wasmtime-wasi-http` now need to include `DEFAULT_FORBIDDEN_HEADERS`, e.g. `DEFAULT_FORBIDDEN_HEADERS.contains(name) || name.as_str() == "custom-forbidden-header"` #11292

+  [#11186](https://github.com/bytecodealliance/wasmtime/pull/11186)

+* Wasmtime's internal implementations of WebAssembly primitives has been
+  refactored to be modeled with safer internal primitives.
