 ## **[Unreleased]**
-- [#579](https://github.com/wasmerio/wasmer/pull/579) Fix bug in caching with LLVM and Singlepass backends.  Add `default-backend-singlepass`, `default-backend-llvm`, and `default-backend-cranelift` features to `wasmer-runtime` to control the `default_compiler()` function (this is a breaking change).  Add `compiler_for_backend` function in `wasmer-runtime`
