MSRV history

The minimum Rust version windows-sys declares (rust-version), and the release that changed it:

0.35.0 (2022-04-05): Rust 1.56
0.36.0 (2022-04-26): Rust 1.46
0.42.0 (2022-09-27): Rust 1.49
0.45.0 (2023-01-21): Rust 1.48
0.52.0 (2023-11-15): Rust 1.56
0.59.0 (2024-07-30): Rust 1.60
0.61.0 (2025-09-04): Rust 1.71

Stuck on an older compiler? Pin the last version that supports it, for example cargo update -p windows-sys --precise <version>, or use resolver 3, which picks compatible versions for you.
