0.62.0

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.
