 ## **[Unreleased]**
 
+- [#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`
 - [#790](https://github.com/wasmerio/wasmer/pull/790) Fix flaky test failure with LLVM, switch to large code model.
