This release is focused on upgrading the ecosystem to standardize on the windows-link crate for universal raw-dylib support on Windows. This avoids all kinds of build complexity and undesirable complexity in dealing with the linker directly via import libs.

To date, the only major Windows crate that still uses the older windows-targets crate for linking is the windows-sys crate. This release updates windows-sys to depend on windows-link and thus raw-dylib unconditionally. This is required for some internal OS and Azure scenarios. It should also meaningfully reduce build time in general since the large windows-targets import lib crates no longer need to be downloaded at all.

I am also using this release as an opportunity to update all of the remaining crates to use the latest version of windows-link which itself receives a major update to finally stop overwriting the ABI (#3689), fixing a cross-target compatibility issue.

With this update, Rust for Windows no longer offers any crates that depend on the windows-targets crate. Although very stable, it will remain supported by this repo for the foreseeable future should there ever be a reason to service it. I do not however plan to provide any non-essential updates to the windows-targets crate. You should instead use the windows-link crate.

Major version updates to existing crates

The windows-bindgen crate (0.63.0) includes updated Windows metadata (#3729) and targets the latest version of the core Windows crates.

The windows-link crate (0.2.0) no longer overwrites the ABI (#3689) avoiding cross-arch incompatibility but is unfortunately a subtle breaking change.

The windows-sys crate (0.61.0) is updated to target the latest windows-link crate and thus raw-dylib (#3724).

The windows crate (0.62.0) is updated to target the latest windows-core crate and provides an API refresh for Windows metadata (#3729).

The windows-core crate (0.62.0) provides a number of improvements for compatibility and target support.

The windows-collections crate (0.3.0) is updated to target the latest windows-core crate.

The windows-future crate (0.3.0) is updated to target the latest windows-core crate and provides new join and when functions for simplifying async continuation (#3708).

The windows-numerics crate (0.3.0) is updated to target the latest windows-core crate.

The windows-registry crate (0.6.0) is updated to target the latest windows-link crate.

The windows-result crate (0.4.0) is updated to target the latest windows-link crate.

The windows-services crate (0.26.0) is updated to target the latest windows-link crate.

The windows-strings crate (0.5.0) is updated to target the latest windows-link crate.

The windows-threading crate (0.2.0) is updated to target the latest windows-link crate and sports a new pool scope for lifetime management (#3696).

Minor version updates to existing crates

The cppwinrt crate (0.3.3) is updated to target the new version of the windows-link crate.

The windows-version crate (0.1.5) is updated to target the new version of the windows-link crate.

This release is primarily to publish #3622, the fix for rust-lang/rust#142330, and make it available to dependent crates and afford them a path forward.

Major version updates to existing crates

The window-sys crate (0.60.1) receives its first update in 11 months to address this issue and update its dependency on the windows-targets crate. This is a major update since metadata changes have caused breaking changes in the generated code.

The windows-bindgen crate (0.62.1) receives an update to correctly generate the link macros using the appropriate calling convention as per #3622. This is a major update since generated code may change.

The cppwinrt crate (0.3.1) is updated to provide access to the recently published version of the cppwinrt compiler. This is a major update since the compiler and base library has some breaking changes.

Minor version updates to existing crates

The windows crate (0.61.2) has been updated to address the calling convention future incomparability warnings. This is a minor update since this is the only change since the last release and is itself not considered a breaking change.

The windows-link crate (0.1.2) and the windows-targets crate (0.53.1) have been updated to address the calling convention future incomparability warnings. This is a minor update since this is the only change since the last release and is itself not considered a breaking change.

What's Changed

• Apply must_use to the bindgen function by @kennykerr in #3605

This is a quick workaround for what appears to be a cargo vendor issue that fails to include some files that are otherwise included by cargo package (#3607).

There are no new crates or major updates in this release.

Minor version updates to existing crates

• The windows-core crate has been update with a workaround for cargo vendor support (#3607).
• The windows-result crate has been update with a workaround for cargo vendor support (#3607).
• The windows-strings crate has been update with a workaround for cargo vendor support (#3607).

What's Changed

• .natvis workaround for cargo vendor by @kennykerr in #3607
• Release 65 by @kennykerr in #3608

Full Changelog: 64...65

New crates in this release

• The windows-services crate provides a simple and safe way to implement Windows services in Rust (#3599).
• The windows-threading crate provides simple, safe, and efficient access to the Windows threading support (#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 (#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).

• Fix circular dependency by @kennykerr in #3549
• Fix semver compatibility issue by @kennykerr in #3554

New crates in this release

• The windows-collections crate defines the Windows collection types like IIterable<T>, IVector<T>, IMap<K, V>, and so on (#3483). It also includes all of the stock implementations for creating such collections (#2346, #2350, #2353). This allows these collections to be used without requiring a dependency on the larger windows crate. This crate also provides an optimized implementation of the standard Iterator trait for the Windows IIterator<T> interface (#3476).

• The windows-future crate defines the Windows async types like IAsyncAction, IAsyncOperation<T>, and so on (#3490). It also includes all of the stock implementations for creating such async types (#3221, #3235). This allows these async types to be used without requiring a dependency on the larger windows crate.

• The windows-link crate provides linker support for Windows (#3450). This is the evolution of the older windows-targets crate but is substantially simpler and more versatile thanks to advances in the Rust compiler since the windows-targets crate was unveiled. Notably, it does not depend on or insert any import libs and can be used with custom libraries, not only those provided by the Windows operating system. All of the crates, with the exception of windows-sys, now depend on the new windows-link crate instead of the older windows-targets crate. This greatly simplifies compilation and also greatly reduces the size of dependencies as the windows-link crate is tiny. The windows-bindgen crate defaults to windows-link but also adds the --link option to override this as needed. You may for example want to use --link windows_targets if you need to stick with the windows-targets crate if you cannot change your MSRV to Rust 1.71 or later as that was the first version to stabilize raw-dylib for all Windows targets. This then lets you continue to use windows-bindgen until you are ready to move to a newer version of Rust.

• The windows-numerics crate defines the Windows numeric types to support graphics-oriented math APIs and calculations (#3488). It also also includes all of the stock implementations for overloaded operators and other transformations. This allows these numeric types to be used without requiring a dependency on the larger windows crate.

Major updates to existing crates

• The windows-bindgen crate provides a number of improvements including new diagnostics (#3498), streamlined and more capable reference support (#3497, #3492), hardened method overloading (#3477), far fewer transmute calls, as well as many other critical fixes and improvements.

• The windows-core crate is largely unchanged but required some breaking changes to support windows-bindgen type system improvements.

• The windows-registry crate continues to improve with generalized support for access rights (#3482), open options (#3461), and other minor improvements.

• The windows crate now delegates to the windows-numerics, windows-future, and windows-collections crates for those types, as well as a number of critical fixes and improvements to features and cfg guards (#3431), and many other small improvements.

Minor updates to existing crates

• The windows-result now includes the BOOL type (#3441) as a core type. This allows this ubiquitous type to be used without requiring a dependency on the larger windows crate.

• The windows-strings crate now depends on the new windows-link crate instead of the older windows-targets crate.

• The windows-version crate now depends on the new windows-link crate instead of the older windows-targets crate.

• The cppwinrt crate includes minor improvements to improve build reliability.
