 ## **[Unreleased]**
 
 - [#822](https://github.com/wasmerio/wasmer/pull/822) Update Cranelift fork version to `0.43.1`
+- [#829](https://github.com/wasmerio/wasmer/pull/829) Fix deps on `make bench-*` commands; benchmarks don't compile other backends now
+- [#807](https://github.com/wasmerio/wasmer/pull/807) Implement Send for `Instance`, breaking change on `ImportObject`, remove method `get_namespace` replaced with `with_namespace` and `maybe_with_namespace`
+- [#817](https://github.com/wasmerio/wasmer/pull/817) Add document for tracking features across backends and language integrations, [docs/feature_matrix.md]
+- [#823](https://github.com/wasmerio/wasmer/issues/823) Improved Emscripten / WASI integration
 - [#821](https://github.com/wasmerio/wasmer/issues/821) Remove patch version on most deps Cargo manifests.  This gives Wasmer library users more control over which versions of the deps they use.
 - [#820](https://github.com/wasmerio/wasmer/issues/820) Remove null-pointer checks in `WasmPtr` from runtime-core, re-add them in Emscripten
 - [#803](https://github.com/wasmerio/wasmer/issues/803) Add method to `Ctx` to invoke functions by their `TableIndex`
