 - Hide nix from the public api such that it can be updated without resulting in a breaking change.
-- Updated nix to version `0.25`.
-- Updated nix to version `0.24`; only use the `ioctl` feature.
+- Updated nix to version `0.26`; only use the `ioctl` feature.
+- Updated `bitflags` to version `2.3`.
 - Use `File.read_exact` instead of `File.read` in `LinuxI2CDevice.read` so that the buffer is filled.
 - Fix the lifetime parameter on `LinuxI2CMessage` to ensure that it does not outlive the buffer it points to.
 - Updated MSRV to 1.60.0.
