 ### Changed
 
+* The WASI Preview 2 `WasiCtxBuilder` type has been refactored, and `WasiCtx` now has private
+  fields.
+  [#6652](https://github.com/bytecodealliance/wasmtime/pull/6652)
+
+* Component `bindgen!` now generates owned types by default instead of based on
+  how they're used
+  [#6648](https://github.com/bytecodealliance/wasmtime/pull/6648)
+
+* Wasmtime/Cranelift on x86-64 can now execute Wasm-SIMD on baseline SSE2, which
+  all x86-64 processors support (as part of the base x86-64 spec). Previously,
+  SSE4.2 extensions were required. This new work allows Wasm with SIMD
+  extensions to execute on processors produced back to 2003.
+  [#6625](https://github.com/bytecodealliance/wasmtime/pull/6625)
+
+
 ### Fixed
 
 * Only export the top-level preview2 module from wasmtime-wasi when the
   `preview2` feature is enabled.
   [#6615](https://github.com/bytecodealliance/wasmtime/pull/6615)

+
+* Fix `AuthenticatedRet` when stack bytes are popped in the aarch64 backend
+  [#6634](https://github.com/bytecodealliance/wasmtime/pull/6634)
+
+* The `fcvt_low_from_sint` instruction has been removed, as it its current
+  behavior can be recovered through a combination of `swiden_low` and
+  `fcvt_from_sint`
