* 2022-06-21: Version 0.0.4
    * Fixed soundness issue regarding argument iterators (`LuaFunction::call`
      and `LuaMachine::callback` relied on `ExactSizeIterator::len` returning
      the correct length, which has been fixed)
    * Removed unnecessary `vec![]` in example and tests (as
      `sandkiste::Function::call` is generic in regard to how a list of
      arguments is provided)
* 2022-05-03: Version 0.0.3
    * Fixed build error on nightly Rust by importing
      `core::ffi::{c_int, c_size_t}` for now instead of using
      `std::ffi` (see
      [commit `07ea143f96` in Rust](https://github.com/rust-lang/rust/commit/07ea143f96929ac7f0b7af0f025be48a472273e5)
      for explanation)
* 2022-04-17: Version 0.0.2
    * Fixed wrong calculation of used memory in custom allocator
    * Fixed error handling when pushing closures to the Lua machine
      (when invoking `lua_pcall` in `cmach_lua_pushclosure`, a wrong stack
      index was provided for the error handler)
    * Added documentation
    * Allow usage of deprecated `bit32` module when using Lua 5.3 (was
      previously stripped when sealing the standard library)
    * Export previously private module `cmach` to allow unsafe access to Lua
    * Avoid an unnecessary reallocation in C function `cmach_lua_errmsgh`
    * Fixed wrong comments in `cmach_lua_getglobal`
* 2022-04-14: Version 0.0.1
