 ## **[Unreleased]**
 
+- [#1147](https://github.com/wasmerio/wasmer/pull/1147) Remove `log` and `trace` macros from `wasmer-runtime-core`, remove `debug` and `trace` features from `wasmer-*` crates, use the `log` crate for logging and use `fern` in the Wasmer CLI binary to output log messages.  To disable colorized output, set the `WASMER_DISABLE_COLOR` environment variable.
 - [#1128](https://github.com/wasmerio/wasmer/pull/1128) Fix a crash when a host function is missing and the `allow_missing_functions` flag is enabled
 - [#1099](https://github.com/wasmerio/wasmer/pull/1099) Remove `backend::Backend` from `wasmer_runtime_core`
 - [#1097](https://github.com/wasmerio/wasmer/pull/1097) Move inline breakpoint outside of runtime backend
