This release includes a host of small improvements and fixes to the windows crate. Notably, the windows-bindgen and windows-metadata crates have been rewritten to avoid the static winmd cache in favor of a stateful metadata reader that allows multiple instances to be used independently (#1777).

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