| - **BREAKING CHANGE** The `wasmer_sys` feature has been renamed to `wasmer_sys_dev` | ||
|
|
||
| ### Added | ||
| - A new feature flag, `wasmer_sys_prod` which enables the Wasmer LLVM compiler. The default, with the `wasmer_sys_dev` feature | ||
| is the Cranelift compiler. The Cranelift compiler is fast, and recommended for development, but the LLVM compiler is supposed | ||
| to be faster and more optimized for production. In testing so far, the compile step is slower with LLVM but the runtime is | ||
| faster. More testing is needed yet to confirm the difference. | ||
| - A new public function `build_module`, which builds a wasmer Module directly, bypassing the `ModuleCache`. It is only implemented for the feature flag `wasmer_wamr`. On the feature flags `wasmer_sys_dev` and `wasmer_sys_prod` it will panic as unimplemented. This enforces the use of the `ModuleCache` when wasmer is used in a compiled mode, but allow bypassing the cache when wasmer is used in interpreter mode as caching is not relevant. | ||

Caching is not relevant because modules are always built JIT? No caching possible?

I know this is just the changelog ;-)

Not relevant because in wasmer_wamr, the wasms are never compiled, they are interpreted. So constructing a wasmer Module is not an expensive process that produces a result we can cache to avoid duplicating that expense.
(in wamr mode, calling serialize() on a Module just gives you back the original wasm bytes)
