 * [#1908](https://github.com/wasmerio/wasmer/pull/1908) Implemented `TryFrom<Value<T>>` for `i32`/`u32`/`i64`/`u64`/`f32`/`f64`
 * [#1927](https://github.com/wasmerio/wasmer/pull/1927) Added mmap support in `Engine::deserialize_from_file` to speed up artifact loading
 * [#1911](https://github.com/wasmerio/wasmer/pull/1911) Generalized signature type in `Function::new` and `Function::new_with_env` to accept owned and reference `FunctionType` as well as array pairs. This allows users to define signatures as constants. Implemented `From<([Type; $N], [Type; $M])>` for `FunctionType` to support this.
+* [#1894](https://github.com/wasmerio/wasmer/pull/1894) Added exports `wasmer::{CraneliftOptLevel, LLVMOptLevel}` to allow using `Cranelift::opt_level` and `LLVM::opt_level` directly via the `wasmer` crate
