 - [#2056](https://github.com/wasmerio/wasmer/pull/2056) Change back to depend on the `enumset` crate instead of `wasmer_enumset`
 
 ### Fixed
+- [#2090](https://github.com/wasmerio/wasmer/pull/2090) `wasi_env_t` needs to be freed with `wasi_env_delete` in the C API.
 - [#2084](https://github.com/wasmerio/wasmer/pull/2084) Avoid calling the function environment finalizer more than once when the environment has been cloned in the C API.
 - [#2069](https://github.com/wasmerio/wasmer/pull/2069) Use the new documentation for `include/README.md` in the Wasmer package.
 - [#2042](https://github.com/wasmerio/wasmer/pull/2042) Parse more exotic environment variables in `wasmer run`.
