This release includes a breaking change in the API (changing the trait `enumset::EnumsetType` to `wasmer_enumset::EnumSetType` and changing `enumset::EnumSet` in signatures to `wasmer_enumset::EnumSet` to work around a breaking change introduced by `syn`) but is being released as a minor version because `1.0.0` is also in a broken state due to a breaking change introduced by `syn` which affects `enumset` and thus `wasmer`.

This change is unlikely to affect any users of `wasmer`, but if it does please change uses of the `enumset` crate to the `wasmer_enumset` crate where possible.

Added
- [2010](https://github.com/wasmerio/wasmer/pull/2010) A new, experimental, minified build of `wasmer` called `wasmer-headless` will now be included with releases. `wasmer-headless` is the `wasmer` VM without any compilers attached, so it can only run precompiled Wasm modules.
- [2005](https://github.com/wasmerio/wasmer/pull/2005) Added the arguments `alias` and `optional` to `WasmerEnv` derive's `export` attribute.

Changed
- [2006](https://github.com/wasmerio/wasmer/pull/2006) Use `wasmer_enumset`, a fork of the `enumset` crate to work around a breaking change in `syn`
- [1985](https://github.com/wasmerio/wasmer/pull/1985) Bump minimum supported Rust version to 1.48

Fixed
- [2007](https://github.com/wasmerio/wasmer/pull/2007) Fix packaging of wapm on Windows

Changed
- [1979](https://github.com/wasmerio/wasmer/pull/1979) `WasmPtr::get_utf8_string` was renamed to `WasmPtr::get_utf8_str` and made `unsafe`.

Fixed
- [1979](https://github.com/wasmerio/wasmer/pull/1979) `WasmPtr::get_utf8_string` now returns a `String`, fixing a soundness issue in certain circumstances. The old functionality is available under a new `unsafe` function, `WasmPtr::get_utf8_str`.

Added

* [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

Changed

* [1941](https://github.com/wasmerio/wasmer/pull/1941) Turn `get_remaining_points`/`set_remaining_points` of the `Metering` middleware into free functions to allow using them in an ahead-of-time compilation setup

- [1949](https://github.com/wasmerio/wasmer/pull/1949) The `wasm_frame_vec_t`, `wasm_functype_vec_t`, `wasm_globaltype_vec_t`, `wasm_memorytype_vec_t`, and `wasm_tabletype_vec_t` are now boxed vectors in the Wasmer C API

* [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.

Changed

- [1865](https://github.com/wasmerio/wasmer/pull/1865) Require that implementors of `WasmerEnv` also implement `Send`, `Sync`, and `Clone`.
