This release includes a rollup of fixes and improvements to the Win32 metadata and many small fixes to the Rust bindings themselves. Notably, fixed-size array parameters, APIs with non-system calling conventions such as cdecl, reproducible builds, and far more accurate import libs.

This release does not include an update to the windows-sys crate, which remains stable and unchanged.
