Release 64

[kennykerr]

New crates in this release

• The windows-services crate provides a simple and safe way to implement Windows services in Rust (Introduce the dedicated windows-services crate #3599).

• The windows-threading crate provides simple, safe, and efficient access to the Windows threading support (Introduce the dedicated windows-threading crate #3595).

Major version updates to existing crates

• The windows-metadata crate is a low-level metadata library for ECMA-335, providing both a reader and writer for the ECMA-335 metadata format (Low-level metadata library for ECMA-335 #3560) used by .NET, WinRT, and more recently the Win32 metadata. It is technically a brand new implementation but reuses the older crate name from my first attempt at a metadata parser in Rust. The emphasis is on low-level. While it is easy to use, the metadata format is intended for tools to use internally. This implementation is very fast and scalable.

Minor version updates to existing crates

The windows-bindgen crate has been updated to use the new windows-threading crate for parallelism to improve reliability and reduce dependencies (#3588, #3595).

The windows-future crate now uses the new windows-threading crate for parallelism (#3595).

The windows-registry crate adds support for key rename (#3567).

The windows-core, windows-result, and windows-strings crates no longer require the windows_debugger_visualizer option to enable natvis support (#3586).
