v0.19.0 - 2022-10-20

Fixed

• Fixed a potential undefined behavior as reported by the miri tool
  with respect to its experimental stacked borrows. (#524)

Changed

• Optimized Wasm to wasmi translation phase by removing unnecessary Wasm
  validation type checks. (#527)
  • Speedups were in the range of 15%.
• Linker::instantiate now takes &self instead of &mut self. (#512)
  • This allows users to easily predefine a linker and reused its definitions
    as shared resource.
• Fixed a bug were Caller::new was public. (#514)
  • It is now a private method as it was meant to be.
• Optimized TypedFunc::call at slight cost of Func::call. (#522)
  • For many parameters and return values the measured improvements are in the range of 25%.
    Note that this is only significant for a large amount of host to Wasm calls of small functions.

Internal
