 This crate contains low level bindings to FFmpeg. You're probably interested in the high level bindings instead: [ffmpeg-next](https://github.com/shssoichiro/ffmpeg-the-third).
 
-A word on versioning: major and minor versions track major and minor versions of FFmpeg, e.g. 4.2.x of this crate has been updated to support the 4.2.x series of FFmpeg. Patch level is reserved for bug fixes of this crate and does not track FFmpeg patch versions.
+A word on versioning: The crate version includes the **maximum supported** FFmpeg version for each release. E.g. `ffmpeg-sys-the-third@2.0.0+ffmpeg-7.0` supports *up to* FFmpeg 7.0. The minimum supported FFmpeg version at the moment is 4.2.
 
 ## Feature flags
 
 In addition to feature flags declared in `Cargo.toml`, this crate performs various compile-time version and feature detections and exposes the results in additional flags. These flags are briefly documented below; run `cargo build -vv` to view more details.
 
-- `ffmpeg_<x>_<y>` flags (new in v4.3.2), e.g. `ffmpeg_4_4`, indicating the FFmpeg installation being compiled against is at least version `<x>.<y>`. Currently available:
