We've just released a minor update to Rubber Band Audio, our friendly and useful little program for messing with the tempo and pitch of audio recordings.
This v2.0.1 release contains two changes: it fixes an incompatibility with certain audio file metadata (affecting macOS and Linux builds), and it improves compatibility with audio playback devices (affecting the Linux build).
Neither fix is relevant to users on Windows. We've nudged the version number of the current Windows release to 2.0.1 as well, for consistency, but there's no real need to update if you're using Windows.
