On https://crates.io/crates/bindgen, the newest version is 0.49.3, while GitHub master (dbe5bab) shows 0.49.2. HEAD (ad0bf8e) points to a distinct commit with a version bump.
I noticed, because #1575 is a breaking change and is included in 0.49.3. Because this version is semver-compatibel, it is automatically upgraded to.
